Technical area

The present invention relates to absorbent articles such as diapers, training pants, adult continence devices, sanitary napkins, elastic underwear parts. More particularly, the invention relates to a topsheet skin care composition which is applied to the topsheet by normal contact and/or movement of the wearer and/or body heat. The skin care compositions of the present invention are selected so that, when transferred during wear, they maintain and/or improve the condition of the wearer's skin;

Prior Art ⁷ The primary function ^of absorbent articles such as disposable diapers and incontinence briefs or undergarments is to absorb and contain body exudates. These articles are therefore intended to prevent body exudates from soiling, wetting or otherwise marking clothing or other articles such as bed linen that come into contact with the wearer. The most common cause of failure of these articles occurs when body exudates leak from gaps between the article and the legs or waist into the adjacent clothing because they are not immediately absorbed within the article and the absorbent article is unable to maintain its proper fit on the wearer, creating gaps that allow the exudates to leak out. For example, urine tends to be placed on the top layer in the pores, so it moves into the gaps between the l. írnt.o viorotrion ti nnsdoiem, íao mlž'.:· oido.áoc o- ot v0o lSOi.O-0! . :í tokut ý not očιί ím and robo '1 i nym : produ 1: top výrobkom:, has a tendency to porno and naeteží si byt imi. .-jbsorlovuria .

Current disposable diapers have a topsheet, a backsheet, an absorbent core, and one or more cuffs, typically elastic cuffs, positioned in contact with the wearer's waist and/or waistband. These elastic cuffs are capable of preventing leakage and overflow from the fluid-laden diaper onto clothing by contacting the edges of the diaper. These elastic cuffs provide a barrier between the ^diaper and the clothing.

Contact ^- clothing and generally, in addition, they provide a sealing action around the legs or waist of the wearer to maintain the waist and minimize slippage generated by elastic components around the legs or waist. However, because the forces are concentrated along a narrow area, resulting in high localized pressures, these elastic cuffs have an increased tendency to create indentations and bruises or reddened areas on the wearer's skin. These skin effects are particularly acute for products worn by children and incontinent elderly people due to the delicacy of their skin and its. sensitivity to even slight pressures or abrasions. These skin effects remain, and continue to be acute occlusion (closure) of the skin caused by these products. y.

The confinement of the skin by a diaper can potentially lead to excessive hydration of the skin and, as a result, it is more susceptible to damage than normal. The wearer's body is more susceptible to wounds due to friction and its contact with elastic cuffs. It is also known that excessively hydrated skin is more susceptible to adverse skin conditions such as diaper rash, cuts, abrasions, bruises and loss of skin tissue.

mechanical or chemical irritation). To address concerns about adverse skin impacts associated with wearing diapers and

• · · · • · » * « · · » · « · • · · · · other absorbent products, the caregiver or wearer often applies skin protective and/or therapeutic (treatment) agents to the buttocks, genitals, anal and/or other areas before the absorbent product is applied to the wearer. This procedure typically involves applying a skin protective product to the skin of their hand and then rubbing it onto the skin of the diaper wearer. In order to eliminate this uneconomical, inconvenient, time-consuming and easily damaged procedure, attempts have been made to produce such absorbent products that include a skin care agent on the top layer of the product.

One substance that has been (or is) used in diaper products to provide a soothing and protective coating is mineral oil. Mineral oil (also known as liquid petrolatum) is a mixture of various liquid hydrocarbons obtained by distilling high-purity petroleum fractions (i.e.

For example, applied mineral oil may transfer onto, into, and through the packaging or wrapping material of a particular diaper product with a skin surface treatment agent. This may create a need for barrier-type packaging or wrapping film to prevent smearing or other leakage of mineral oil from the diaper product.

U.S. Patent 3,489,148 to Duncan et al. discloses a baby diaper comprising a hydrophobic and oleophobic topsheet in which a portion of the topsheet is coated with a discontinuous layer of oleaginous material. The major disadvantage of the diapers disclosed in the Duncan et al. reference is that the hydrophobic and oleophobic topsheets are slow to promote urine transfer to the underlying absorbent cores.

In addition to the fluid movement problems encountered by applying liquid compositions to the topsheet, the prior art has failed to consider the detrimental skin care effects of using cuffs, nor how to treat cuffs so that the skin care compositions disposed thereon remain on the cuff, are transferred to the wearer's skin in an effective amount, and provide skin care benefits. The prior art has also failed to recognize that treating the topsheet of the product alone does not necessarily transfer a particular composition to all critical areas of the wearer's skin.

Therefore, it is desirable to provide an absorbent article having cuffs in which, to provide skin care benefits, a skin care agent is disposed on the cuffs, particularly in areas where the sock contacts the wearer's calf during wear. In order to provide skin care benefits,

It is therefore desirable to provide diapers or other absorbent articles having one or more cuffs with a skin care composition arranged thereon that: (1) have desirable therapeutic and protective coating effects, (2) do not require relatively high levels of skin care compositions, coatings, which are (e.g., mineral oil), and do not necessarily require packaging materials.

It is therefore an object of the present invention to provide a diaper or absorbent article having one or more cuffs with a skin care composition disposed thereon, wherein at least a portion of the composition is transferred to the skin of the wearer to provide a desired benefit to the wearer, including reduced skin irritation, reduced redness, therapeutic effects including reduced erythema and/or diaper rash, and/or reduced adherence of fecal materials to the skin, thereby improving the cleansing of fecal material. When hydroscopic skin care compositions are used, it is another object of the present invention to provide a containment/barrier function.

These and other objects are achieved by the use of the present invention, which will become readily apparent from a reading of the following description.

As used herein, the term "cuff" includes leg cuffs including barrier cuffs, seal cuffs, combinations and variations thereof; transverse barriers and baffles and pockets/spacers; side panels; as well as waist cuffs including waist flaps, waist bands, waist closures and unitary waist closures/bands and combinations of all or any of these.

Importantly, the compositions of the present invention provide protective and therapeutic benefits when applied to the skin of the wearer, including reducing erythema and/or diaper rash. The skin care composition may also act to reduce the amount of skin irritation in the area where the cuff contacts the wearer's skin, resulting in less irritation of the skin. In addition _, the protective coating on the wearer's skin may reduce the adhesion of fecal materials to the skin, thereby improving ease of cleaning.

In addition, special barrier or packaging materials are not required in the packaging of these treated products of the present invention.

In one preferred embodiment, the absorbent article of the present invention includes a skin care composition disposed on (or movable to) the cuffs and the topsheet. Applicants have found that these preferred articles enhance the delivery of the composition to the wearer's skin, resulting in increased therapeutic and/or protective benefits as discussed herein. In this regard, the increased delivery will be realized as increased skin coverage (i.e., skin area) and/or the amount of composition delivered to a given skin area.

A) Absorbent product

As used herein, the term absorbent article refers to those devices that absorb and contain body exudates and, more specifically, refers to devices that are placed against the skin of a wearer for the purpose of absorbing and containing various exudates secreted by his body. The term “disposable” is used herein to describe absorbent articles that are not intended to be washed or otherwise returned to their original condition or reused as an absorbent article after a single use. Examples of disposable absorbent articles include feminine hygiene products such as sanitary napkins, sanitary pads and panty liners, diapers, incontinence products such as panties or underwear, diaper liners, diaper holders, pull-on diapers, training pants, and the like. Disposable absorbent articles typically include a chassis (or containment assembly) comprising an outer cover layer comprising a liquid pervious top layer and a liquid impervious back layer, with an absorbent core encapsulated within the outer cover layer, preferably located between the backing layer and the backing layer.

¹ o .ό [ io τ a ' ou ¹ u bs ui pc π : v /rou ky aiei i. chsou ca sti, oosahujioi on individual layers of these components have two main surfaces (the body-facing surface and the garment-facing surface). As used herein, the body-facing surface (also referred to as the body-contacting surface or skin-contacting surface) means that surface of a given product or component that is intended to be worn toward or in proximity to the wearer's body, while the garment-facing surface is on the opposite side and is intended to be worn facing the wearer's undergarment components.

generally discusses absorbent core, topsheet, and backsheet materials useful in disposable absorbent articles. It is understood that this general description applies to those components of the specific absorbent articles illustrated in Fig. 1-1 and further described below, in addition to those of other disposable absorbent articles generally described herein.

Generally, the absorbent core is capable of absorbing or retaining fluids (e.g., menses, urine, and/or other body exudates). The absorbent core is preferably compressible, conformable, and non-irritating to the skin of the wearer. The absorbent core can be manufactured in a wide variety of sizes and shapes (e.g., rectangular, sheepskin, hourglass, T-shaped, dogbone, etc.) according to the invention. The absorbent core can comprise any of a wide variety of fluid absorbing materials, particularly those used in absorbent articles, such as comminuted wood pulp, which is generally referred to as airfelt.

The arrangement and construction of the absorbent core may also vary (for example, the absorbent core may have different weight zones, and/or a profile such that it is thicker in the center; hydrophilic gradients; gradients of the absorbent component (composite), for example, superabsorbent gradients; zones of lower average density and lower average basis weight of the base, for example, acquisition zones, or may contain one or more layers or structures). The total absorbent capacity of the absorbent core, however, should be compatible with the intended absorbent load determined by the product. Furthermore, the size and absorbent capacity to accommodate the cores can vary, with different uses such as diapers, incontinence pads, training pants, panty liners, normal sanitary napkins and night sanitary napkins, and abv has adapted to its wearers ranging from infants to adults.

The absorbent core may also include other absorbent components that are often used in absorbent products, for example, a dust layer, a leakage or acquisition layer (fluid shock wave control layer), or a secondary topsheet to enhance wearer comfort.

The top layer is preferably conformable, soft-feeling, and non-irritating to the wearer's skin. Furthermore, the top layer

Suitable woven and nonwoven materials may be composed of natural fibers (e.g., wood or cotton fibers), synthetic fibers (e.g., polymer fibers such as polyester, polypropylene, or polyethylene fibers), bicomponent fibers, natural and man-made fibers. When the heat layer comprises a nonwoven structure, the structure may be manufactured by a wide variety of known techniques. For example, the structure may be nonwoven, carded, wet-laid, melt-blown, hydroentangled, a combination of the foregoing, or the like.

The backsheet is preferably liquid-impermeable (e.g., menses and/or urine), at least to the crotch region of the absorbent article, and is preferably made of a thin plastic film, although other flexible, liquid-impermeable materials may also be used. As used herein, the term flexible refers to those materials that are pliable and readily conform to the contours of the human body so that the exudates, the absorbent core, and the article are permeable to the overall shape of the body. The backsheet prevents the absorbed and retained fluids from contacting the absorbent article.

Exemplary polyethylene films are manufactured by Oiopay Corporation of Oi ricinnat i , under the designation 1018 — 1.401, and Tredeqar Film Products of Hautc, India, under the designation XP-39385. The backsheet is preferably embossed and/or matte-finished to provide a more cloth-like appearance. Further, the backsheet may permit vapors to escape from the absorbent core (i.e., the backsheet is breathable) while still preventing the passage of exudates through the backsheet. (An example of a breathable backsheet suitable for use herein is described in US Patent No. 5,571,096, entitled "Absorbent Article with Breathable Side Panels", issued to Dobran, Davis and Weirich on November 5, 1996, which is incorporated herein by reference.) The size of a particular backsheet is dictated by the size of the absorbent core and the precise pattern chosen for the absorbent article.

The backsheet and the topsheet are positioned adjacent the garment surface and the body surface, respectively, of the absorbent core. The absorbent core is preferably joined to the topsheet, the backsheet, or both, in any manner known in the art, by means of attachment means such as those well known in the art. However, embodiments of the present invention are contemplated in which portions of the entire absorbent core are unattached to either the topsheet, the backsheet, or both.

As used herein, the term "diaper" refers to an absorbent article generally worn by infants or incontinent individuals and which is worn around the lower torso. In other words, the term diaper includes training pants, adult incontinence devices, and the like. The present invention is also applicable to other types of disposable products such as sanitary napkins and panty liners that include cuffs.

Fig. 1 is a plan view of a diaper 20 of the present invention in its flat, unrolled condition (i.e., with all of the contraction-inducing material pulled out), with the portions of the diaper that are attached to the body of the wearer, e.g., an infant diaper, the diaper 20 being assembled in a manner that is convenient for the viewer to see.

The diaper 20 includes an assembly (Chassis) including (i) an outer cover layer including a liquid pervious topsheet 36 and a liquid impervious backsheet 42, and (ii) an absorbent core 44 having side edges 46; a fastening system including a belt attachment portion 46; a fastening pS; sealing cuffs 56, each including a side flap 56 and a flap elastic portion 60; barrier cuffs 62 including a barrier cuff portion 63 having a proximal (closer to the body) edge 64, a distal (more distant) edge 66 and a terminal 74; and a spacer means such as a spacer elastic portion 76 for spacing the distal edge 66 from the topsheet. The diaper 20 additionally includes closure portions 76 for securing to the closure ends 74 of each barrier cuff 62. While the components of this diaper may be assembled in a variety of well-known assemblies, a preferred diaper assembly is generally described in U.S. Patent 4,695,278, issued June 1987, and which patent is incorporated herein by reference.

As shown in Fig. 1, a skin care composition 72 is disposed on each barrier cuff 62, the composition preferably being disposed on the body surface of the barrier cuff so that the skin care composition can be readily transferred to the wearer's skin during wear. In the illustrated embodiment, the skin care composition 72 is disposed adjacent the distal edge 66, preferably at least in the crotch region 26. More preferably, the skin care composition 72 is disposed on the distal edge 66. The barrier cuffs 62 most preferably include one or more strips of skin care composition 72 disposed thereon. In the illustrated embodiment, the skin care composition 72 is disposed only on a portion of the barrier cuff 62. For certain skin care compositions, it is preferred to avoid applying the skin care composition to the portions of the barrier cuff adjacent the ends of the large elastic portions to ensure that there is no elastic creep due to the interaction of the skin care composition and the adhesive. As shown in FIG. 1, in the preferred embodiment, the skin care agent 72 is not adjacent the ends of the elasticized waist region portion 76 (although it may also be arranged adjacent the ends in the rear waist region.) Alternatively, an adhesive compatible with the skin care agent may be used such that the placement of the skin care agent on the cuff is limited relative to the portion.) The pressure has been discussed. The agent is applied to the garment surface of the barrier cuff and allowed to "pass through" to the body surface so as to increase the hydro!ability of the barrier cuffs, as well as being arranged on the body-facing surface to provide skin care benefits.

The barrier cuff 62 is shown as comprising a separate element, the barrier cuff portion 63 attached to the topsheet 38; the proximal (nearer) edge 64 is formed by attaching the barrier cuff portion 63 to the topsheet 36 via a proximal attachment portion 92. The garment surface 68 of the barrier cuff 62 (also referred to as the center surface or inner surface of the barrier cuff) is attached to the body surface 40 by the closure portion 78. Thus, the distal (more distant) edge 66 is closed (i.e., not spaced outwardly from the body surface 40.) It should be noted that the expansion elastic portion is not provided in this region because the distal edge 66 is not designed to be spaced from the body surface 40 in the waist region. Therefore, the barrier cuff 62 is not open or prepared to restrict the flow of body exudates in this area. In this particular embodiment, the skin care product is also preferably not disposed on the barrier cuff in the rear waist area.

Fig. 3 is a partial cross-sectional view taken along line 33 of Fig. 1 and illustrates the assembly of the crotch region 26 as it is shaped prior to application to the wearer (i.e., the diaper 20 is similar to an elastic waistband). The absorbent core 44 includes an absorbent layer 44, which is shown as being completely encapsulated by layers of fabric 50 and 52. The absorbent core 44 is disposed between a topsheet 38 and a backsheet 42; both the topsheet 38 and the backsheet 42 extend beyond a side edge 46 of the absorbent core 44 and define a side flap. The side panels of the layers 38 and 42 are preferably bonded together by means of a non-adhesive flap. The top layer 38 and the bottom layer 42 also enclose flap elastic portions 60 adjacent the longitudinal edge 30. These flap elastic portions 60 are secured in the top and bottom layers of the formed side flap 58, preferably by elastic attachment portions 90.

The diaper assembly is shown in the drawings as comprising the main body portion (retention assembly) of the diaper. This assembly comprises at least an absorbent core and preferably an outer cover layer comprising a topsheet and a backsheet. When the absorbent article comprises a separate holder and cover, the assembly generally comprises a holder and cover (i.e. the assembly comprises one or more layers of material to define the holder, while the cover comprises an absorbent composite such as a topsheet, a backsheet and an absorbent core.) For unitary absorbent articles, this assembly comprises the main diaper structure with other modifications added to form the composite diaper structure, thus a diaper assembly comprises a topsheet, a backsheet and an absorbent core.

The topsheet 38, which is particularly suitable for use in the diaper 20, is carded and thermally bonded (bonded) by means well known to those skilled in the art of fabric technology. A satisfactory topsheet for the present invention comprises staple length polypropylene fibers having a yarn unit weight of about 2.2. As used herein, the term staple length fibers refers to those fibers having a length of at least 15.9 mm (0.625 inches). Preferably, the topsheet has a basis weight of from about 14 to about 25 grams per square meter. A suitable topsheet is manufactured by Veratec, Inc., under the designation Pnei.zaná Vnikonu s area· ¹ .! vrno, >2 arama on čsverctni f Ua.Ípoie, Massachusetts, 000 preferred upper layer (o tumor oomoany, Alternative as is available from lirmy Fiberwcb North America, Tne. of 2 ; mošen vi 11 e, under the designation 9694.

The topsheet 38 of the diaper 20 is preferably made of a hydrophilic material to promote rapid transfer of fluids (e.g., urine) through the topsheet. If the topsheet is made of a hydrophobic material, preferably » * a a · · aiespon p

It reduces the likelihood that body exudates will flow off the topsheet rather than being drawn through the topsheet and absorbed by the absorbent core. The topsheet may be rendered hydrophilic by treating it with a surface-active agent. Suitable methods of treating the topsheet with this agent include spraying the material with the agent and immersing the material in it. This treatment and hydrophilicity are discussed in more detail in U.S. Patent No. 4,988,344, entitled

As discussed above, a skin care composition disposed on both the cuffs and the topsheet will facilitate the transfer of a given composition to a greater portion of the skin, in terms of surface area, relative to the cuff treatment alone. In addition, application to both components may allow for the delivery of a greater amount of skin care composition to a given area of the wearer and/or the delivery of a skin treatment composition with a different composition for different effects (benefits) on the skin.

In a preferred embodiment of the diaper as described herein, the backsheet 42 has a modified hourglass shape extending beyond the absorbent core around the entire circumference of the diaper. The backsheet is preferably a soft, fabric-structured laminate comprising an optionally apertured, polymeric film.

Each leg cuff may include several different features to limit the escape of body exudates in the leg regions. (These leg cuffs may and sometimes are also referred to as leg bands, side flaps, barrier cuffs, elastic leg cuffs, seal cuffs, or elastic cuffs.) U.S. Patent No. 3,860,003, incorporated herein by reference, describes a disposable diaper 20 that provides a leg opening with a side flap and one or more elastic portions to secure an elasticized leg cuff (seal cuff). U.S. Patent No. 4,909,803, entitled Disposable Absorbent Article with Elasticized Flaps, issued to Aziz et al. on 20

et.

March, 1990 and incorporated herein by reference, describes a disposable diaper 20 having stand-up elasticized flaps (barrier cuffs) to improve containment in the leg region. U.S. Patent 4,695,278, entitled Absorbent Product with Double Cuffs, issued to Lawson on September 22, 1987 and incorporated herein by reference, describes a disposable diaper 20 having double cuffs comprising a sealing cuff and a barrier cuff. Although each elasticized cuff may be similarly configured to be similar to any of the leg bands, side flaps, barrier cuffs, or elastic cuffs described above, it is preferred that each leg cuff include barrier cuffs 62 and sealing cuffs 56, as described in detail below.

Each barrier cuff 62 is a flexible member having a proximal (closer to the body) edge 64, a distal (further from the body) edge 66, a garment surface 68 (also referred to as the inner surface) and a body surface 70 (also referred to as the outer surface). When the diaper is worn, the diaper and the body surface 70 are oriented toward the wearer's skin. The barrier cuff 62 can be made from a wide variety of materials such as polypropylene, polyester, rayon, nylon, foams, nonwovens, plastic films, formed films and elastic films or foams. A number of manufacturing methods can be used to manufacture the barrier cuff.

• *

For example, the barrier sleeve 62 may be woven, nonwoven, multi-filament nonwoven, meltblown nonwoven, carded, coated, laminated, or the like. The preferred barrier sleeve 62 comprises a polypropylene material that does not contain any coating or surfactant to render it impervious to liquids. An exemplary polypropylene fibrous nonwoven material is manufactured by Crown Zellerbach Company under the Celestra designation. A particularly preferred nonwoven material is a carded nonwoven material such as that available from PGl of Landisville, New Jersey under the designation 62100. Alternatively, the material may be a nonwoven structure supplied by Corovin GmbH, of Peine, Germany, under the designation MD300A. Additionally, due to the hydrophobic skin care compositions used in the present invention, the barrier cuff may be made of a hydrophilic material and have a hydrophobic skin care composition disposed thereon to improve its barrier properties.

As shown in Figs. 1 and 3, the barrier cuff 62 and more particularly the proximal (closer to the body) edge 64 is arranged in a direction along the length thereof, preferably inwardly of the sealing cuff 16. The term "inwardly" is defined as a direction, towards the central axis (34 or 36, respectively) of the diaper, which is parallel to the respective edge of the diaper along which the sealing cuff is arranged. The barrier cuff 62 is arranged adjacent the sealing cuff 66 of the body exudates. It is arranged in a direction d<

The barrier cuff 62 is preferably inside the seal cuff 56 so that exudates, and particularly loose fecal material, which is not readily absorbed and tends to float along the surface toward the body 40, will contact the barrier cuff 62 before it can contact the seal cuff 56. The barrier cuff 62 is more preferably disposed between the cup elastic portion 60 of the seal cuff 56 and the longitudinal center axis 36 of the diaper 20. More preferably, the barrier cuff 62 is disposed between the cup elastic portion 60 and the side edge 46 of the absorbent core 44 in the crotch region 26 of the diaper 20.

The proximal edge 64 and the distal edge 66 are spaced apart from each other and define the width of the barrier cuff 62. The proximal edge 64 and the distal edge 66 may be in parallel, non-parallel, rectilinear, or curvilinear relationship to each other. In addition, the barrier cuff 62 may have a variety of different cross-sectional areas including circular, square, rectangular, or any other shape as shown in Fig. 3. The proximal edge 64 is preferably spaced apart from the distal edge 66 in parallel and rectilinear relationship to each other to provide a barrier cuff ₆₂ having uniform widths.

The preferred embodiment of the diaper 20 shown in Figs. 2 and 3 is provided with a barrier cuff 62 connected to the topsheet 33. The term "connected" includes any means for connecting the barrier cuff 62 to the diaper 20, and includes embodiments in which

is a barrier cuff 62 separate element having proximal margin 64 straight or o .indirectly connected to dive layer 3h (i.e., integral) or the renderings in which it is barrier cuff 62nd birthday z.e of the same element of heaven matter 11 u 3 a k o i e upper, layer 38, tt if for xi has ini. okrai 6 4 is continuous and

2, the absorbent core 44, the topsheet, or any combination of these or other elements of the diaper 20. In a preferred diaper 20, the barrier cuffs 62 are integral with the topsheet 36. The integral barrier cuff 62 is preferably formed by a strip of material, the barrier cuff portion 63, which is attached to the topsheet by a proximal (closer to the body) fastening portion 92, the distal (further from the body) edge 66 being formed by folding the ends of the barrier cuff portions 63 onto themselves.

The distal edge 66 is preferably arranged inwardly of the proximal edge 64 to provide a more effective barrier to the flow of exudate. The distal edges 66 are held inwardly of the proximal edges 64 by the locking portions 76 to prevent their reversal. Although the distal edges 66 may alternatively be arranged in other positions relative to the proximal edges 64, these positions are not preferred.

The distal edge 66 is preferably not attached to any other element in at least the crotch region 26 of the diaper 20, so that it can be spaced away from the body-facing surface 40 of the topsheet 36. The distal edge 66 is preferably spaced away from the body-facing surface 40 to increase the containment of the article. As used herein, the term "spaced" includes embodiments in which the distal edges 66 can occupy one or more positions relative to the body-facing surface 40 of the topsheet 38, including sometimes occupying a position adjacent to the body-facing surface 40 of the topsheet 38.

The 9*9 * 9 sealing cuff includes a flexible side flap 5b and a flap elastic portion 60, as described in detail in U.S. Patent No. 3,860,003, issued to Bueil on January 14, 1975, and incorporated herein by reference. In addition, a method and apparatus suitable for manufacturing a disposable diaper having elastic sealing cuffs 56 are described in U.S. Patent No. 4,081,301, entitled "Method and Apparatus for Continuously Attaching Fine, Expanded Elastic Strands to Predetermined, Isolated Portions of Disposable Absorbent Articles," issued to Bueil on March 28, 1987, and incorporated herein by reference.

The side flap 56 should be highly flexible and therefore contractible so that the flap elastics 60 can gather the side flap 58 and provide a sealing flap 56 around the legs or waist of the wearer. The side flaps 58 are preferably that portion of the diaper 20 that is between the circumference and the edges of the absorbent core 44. Thus, in a preferred embodiment of the present invention, as shown in FIG.

The functional cuffs 58 may be in a contractible state in at least two ways. For example, the side _flaps 53 may be expanded and secured to the side flaps 58 while the side flaps 58 are in their unstretched state. Alternatively, the side flaps 53 may be contracted, such as by pleating, and the flap elastics 60 secured to the contracted side flaps 58 while the flap elastics 60 are in their unstretched or unstretched state. The sealing cuffs may alternatively comprise a variety of different, elastically extensible structures such as elastic nonwovens or foams; stretch laminates such as those described in U.S. Patent No. 5,151,092, issued to Bueil et al. on September 29, 1992, incorporated herein by reference; and structural elastic-like films (SELFs) such as those described in U.S. Patent No. 5,518,801, issued to Chappelcvi et al. on May 21, 1996, incorporated herein by reference.

In the embodiment shown in Fig. 1, the flap elastic portions 60 extend substantially the entire length of the side flaps 58 in the crotch region 26 of the diaper 20. Alternatively, the flap elastic portions may extend the entire length of the diaper or any other length suitable to provide a sealing cuff. The length of the cuff depends on the design of the diaper.

A more detailed description of the manner in which the flap elastics 60 may be positioned and secured to the diaper 20 can be found in U.S. Patent No. 4,253,461, issued to Strickiand and Vissoher on March 3, 1981, and in U.S. Patent No. 4,031,301, issued to Ruell on March 28, 1987, both of which are incorporated herein by reference.

One flap elastic portion 60 that has been found suitable is an elastic strand made from natural rubber such as is available from Easthampton Rubber Thread Company of Stewart, Va., under the trade name L-900 Rubber Compound. Other suitable flap elastic portions 60 may be made from natural rubber, such as the elastic band sold under the trade name Eulflex 9211 by Fulflex Company of Scotland, N.C. An exemplary elastic portion is a strand of Lycra, such as is available from DuPont Co. of Waynesboro, Virginia, under the trade name Lycra-XA T-15I. The flap elastic portion 60 may also include any heat shrinkable material well known in the art. Other suitable flap elastic portions 60 may include a wide variety of materials well known in the art, including elastomeric polyurethanes, elastomeric rubbers, and elastomeric rubbers.

A skin care composition 72 is disposed on the body surface (applied to the body surface or applied so as to be movable to the body surface) of each barrier cuff 62 to be transferred to the wearer's skin to provide the skin benefits discussed herein.

The diaper 20 is applied to its wearer by placing the rear waist region 24 under the wearer's back and pulling the remainder of the diaper 20 between the wearer's legs, such that the front waist region 22 is positioned across the front of the person. The ends of the tape fasteners 54 of the tape tabs are then preferably attached to the attachment member 55 and the diaper 20 is closed. In this manner, the barrier cuffs 62 should be arranged in the crotch region of the wearer and should provide the respective arrangement and functions described hereinabove. Once applied, the distal edges 66 of the barrier cuff 62 extend across the groin areas and diverge upwardly along both buttocks of the wearer.

What year?

The present invention, in part ^, includes a containment assembly (chassis) and a body attached thereto. The body of the invention, in part, includes (i) an outer cover layer comprising a portion of the topsheet 38 and a portion of the bottomsheet 40, and (ii) an absorbent core 44,

The cuffs each include a barrier cuff 762 and a sealing cuff 756. The barrier cuff 762 includes a separate cuff portion 763 having a flap portion 702 and a channel portion 704.

The flap portion 702 is formed by joining a portion of the barrier cuff component 763 to the backsheet 42 adjacent the longitudinal edge 30 of the diaper by means of flap attachment portions 88 such as an adhesive; A leak-resistant seal is formed by the flap attachment portions 68, the flap portion 68, and the backsheet 42 to provide protection against leakage of fluids seeping along the topsheet 38. The flap portion 702 and the backsheet 402 define a side flap 758 of the sealing cuff 756 and enclose the flap elastic portions 760. The flap elastic portions 760 are secured to the flap portion and the backsheet of the formed side flap 758 by elastic attachment portions 90. The sealing cuff 756 is thereby formed by the side, cuff 758, and flap elastic portions 760.

The channel portion 704 of the barrier cuff 762 is associated with the flap portion 702 and has a proximal edge 64 and a distal edge 66. The proximal edge 64 is preferably formed toward the inside of the sealing cuff 756, more preferably between the side edge 46 of the absorbent core and the flap elastic portion; the barrier cuff 763 has a proximal attachment portion of the connection to form the proximal edges of ^{the sealing cuff} 756 to prevent leakage of fluid.

760, by attaching a segment of the bottom layer 42 to a means 92 such as a mechanical/pressure seal, resisting leakage along the front of the diaper 20. The distal end 66 is preferably arranged in the direction of the U'1-m'aje 64 and is not attached to any part of the barrier sleeve 20. As shown in Fig. 7, it is preferably formed by folding the ends 763 back onto themselves and attaching the ends 763 to the distal end 66 of the barrier sleeve 20.

0 0 attachment portion 96 to form a tunnel. A spacer means such as a spacer elastic portion 76 is housed within this tunnel; the spacer elastic portion 76 is secured in the barrier cuff 762 by elastic attachment portions 94. (As an alternative embodiment, the pull string elastics are attached to the barrier cuff element only at the ends of the spacer elastic portion so that the central segment of the elastic "floats" within the tunnel. This pull string elastic is described in more detail in U.S. Patent 4,816,025, issued to Richardson on March 28, 1989, which is incorporated herein by reference.) The distal edge 66 is thus positioned outwardly from the body surface 40 of the topsheet .38 by the gathering action of the spacer elastic portion '? 7 .

In the illustrated embodiment, the topsheet 38 is positioned adjacent the body surface of the absorbent core 44 and extends beyond the lateral edge 66 of the absorbent core 44 but terminates inwardly of the proximal edge 64. (Alternatively, the topsheet may extend outwardly beyond the proximal edge but terminate inwardly of the flap attachment portion 88 to achieve the advantages of the structure.) A more detailed description of the cuff assembly of this embodiment is described in U.S. Patent 4,797,454, "Absorbent Article Having Leakage-Resistant, Double Cuff," issued to Dragoo on January 3, 1989, which is hereby incorporated by reference.

AA »A of the channel 704. For example, the flap portion 702 need not be hydrophobic, nor extend outwardly toward the longitudinal edge 30. Additionally, each of the barrier cuffs 762 need not have a flap portion, so that the flap portion may be omitted entirely. However, the flap portion is preferably hydrophobic, conformable, soft-feeling, and non-irritating to the wearer's skin as it contacts the wearer's legs during wear.

An effective amount of a skin care composition is disposed on the cuff to provide a skin care benefit to the wearer. In order to deliver the skin care composition to the wearer's skin during wear, it is preferred to dispose the skin care composition on those portions of the cuff that will contact the wearer's skin. Accordingly, the skin care composition may be disposed on both surfaces of the cuff, one corner of the cuff, or portions of one or both surfaces. In the embodiment shown in Fig. 7, the skin care composition may be disposed on a portion of the flap 702, a portion of the channel 704, or both. If the skin care composition is disposed on both the flap portion and the channel portion, the composition of the skin care composition disposed on each of them need not be the same. In fact, each skin care composition may have a different composition and properties to provide ^a different benefit. For example, a first skin care product, which treats acne, may be arranged in a portion of the channel, while a second skin care product, the skin, may be arranged in a portion of the channel, as shown in the embodiment.

A first skin care agent is disposed on a portion of the channel, preferably on the facing surface; a second skin care agent 72 ¹ is disposed on a portion of the flap, preferably on its body-facing surface; and a third skin care agent 72 ¹¹ is disposed on the top layer, preferably on its body-facing surface. The composition of each skin care agent need not be the same; however, in this particular embodiment, the composition of the skin care agent is the same. The skin care agent is disposed in an effective amount to transfer the skin care agent to the skin of the wearer.

As shown in Fig. 1, the skin care agent is preferably disposed on discrete portions of the flap and the channel portion. More preferably, the skin care agent is applied in one or more strips, most preferably the strip or strips are flush with those surfaces that lie on the flap elastic portion or the spacer elastic portion. The first skin care agent is disposed in a wide strip (about 1.4 inches, i.e. 35.56 mm) extending from the distal edge 66 toward the proximal edge. 64. The length of this strip extends along portions of the long, about cuff length of the cuff.

The gap between the flaps of 9.65 cm (about 1.7 cm) is such that the portion of the barrier element 763 in the front waist region does not have a diaper care device 72 arranged thereon. (See, for example, Fig. 1). A plurality of strips of a second _diaper care device are disposed on the flap portion 72 _.

The skin care product also applied to the skin will move or migrate through the surface to the body of the barrier cuff portion, transferring it to the wearer's body and providing the skin with the foam discussed herein.

A skin care composition may also be disposed on the topsheet to provide a different benefit or the same benefit as that provided on the barrier cuff. An example of a skin care composition for the topsheet is described in U.S. Patent No. 5,643,588, issued to Roe et al. on July 1, 1997, incorporated herein by reference.

Fig. 8 is another, alternative embodiment of a treated cuff, particularly a breathable, treated elastic leg cuff of the present invention. As shown in Fig. 8, a diaper 830 includes an assembly (chassis) comprising an outer cover layer comprising a topsheet 38 and a backsheet 42, and an absorbent core 44 encapsulated within the outer cover layer, preferably between the topsheet 38 and the backsheet 42. Leg cuffs 8 5 6 include a side flap 858 and an elastic portion: 860. Leg cuff

When present, the amount of emollient that may be included in a particular composition (or mixture) depends on the specific skin effects, other similar factors, and the composition. The composition will contain from about 100% by weight of the emollient, the desired components in the composition, and will contain from about 0 to about 95% by weight of the emollient. Preferably, the composition will contain from about 20 to about 80%, and more preferably, from about 40 to about 100% by weight of the emollient.

Another optional, but particularly key component of certain compositions useful in the present invention is an agent capable of immobilizing the composition (containing the preferred emollient and/or other skin protection/conditioning agents) at a desired location in or on the cuff to be treated. Because certain preferred emollients in the composition have a plastic or fluid consistency at 20 ^° C, they tend to flow or migrate even when subjected to moderate shear. When applied to the body-facing surface or other areas of the cuff, particularly in a molten or molten state, the emollient will not remain primarily in or on the treated area. Instead, the emollient will tend to migrate and flow to undesirable locations in or on the cuff. The company produces .

Immobilization (iíci) the tendency of the plasticizer to migrate or the plasticizer is primarily ^localized φ r’ Q C h r' θ ,d ]z c. t i £ Γ '', flow, by maintaining the composition on which the composition is applied. It is believed that this is due, in part, to the fact that the immobilizing agent increases the melting point and/or viscosity of the composition above that of the plasticizer. Since this immobilizing agent is preferably miscible with the plasticizer (or dissolved in it by means of a suitable emulsifier, or dispersed therein), it traps the plasticizer on the wearer-facing surface of the cuff or in the area to which it is applied.

It is also advantageous to lock the immobilizing agent to the wearer by contacting the surface or area of the cuff to which it is applied. This can be achieved by using immobilizing agents that rapidly set (i.e., solidify) upon application to the cuff. Additionally, external cooling of the treated cuff by means of blowers, fans, cold rollers, etc., can accelerate the crystallization of the immobilizing agent.

In addition to being miscible with (or soluble in) the given plasticizer, this plasticizer will preferably undergo melting, which will provide a mixture that is solid or semi-solid at ambient temperature. In this regard, preferred immobilizing agents will have a melting point of at least about

Preferred immobilizing compositions comprise ^C16 - _C16 fatty alcohols, most preferably crystalline _high melting materials selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol, and mixtures thereof (the linear structure of these materials may accelerate solidification on the treated cuff). Mixtures of cetyl alcohol and stearyl alcohol are particularly preferred. Other preferred immobilizing _C18 - _C18 fatty acids, from the group consisting of palmitic acid, stearic acid, palmitic acid, and salicylic acid are most preferred.

R ² may be selected to provide, for example, cocamides, stearamides, oleamides, lauramides, myristamides, capricamides, palmitamides, tallow amides, etc. The Z moiety may be 1-deoxyglucityl, 2-deoxyfructityl, 1-deoxymaityl, 1-deoxylactityl, 1-deoxygalactityl, 1-deoxymannityl, 1-deoxymannityl, 1-deoxymannityl totriotityl, etc.

The most preferred polyhydroxy fatty acid amides have the general formula:

R h i

R ² - C - N - CiH'

----CH-----CH-- wherein ^R1 is methyl or methoxypropyl; ^R2 is a straight chain alkyl or alkenyl group from C1 to C4. These include N-lauryl-N-methylglucarnamide, N-auryl-N-methoxypropylglucarnamide, N-cocoyl-N-methylglucarnamide, N-cocoyl-N-methylglucarnamide, N-pa-Imi-ty-N-N-methyl-propylglucarnamide, N-a-1

As previously noted, some immobilizing agents may require an emulsifier for solubility in the emollient. This is particularly the case for certain glucamides such as N-alkyl-N-methoxypropyl glucamides having HLB values of at least 7. Suitable emulsifiers are typically those having HLB values of less than about 7. In this regard, sorbitan esters have been previously described, such as sorbitan stearates,

HLB of about 4.9 or less have been found useful in dissolving these immobilizing agents. Suitable emulsifiers include steareth-2 ethers of stearyl alcohol, which are in petrolatum. Others (polyethylene glycol conforming to the formula

CH ₃ ( CH ₂ ) ₁₇ (OCH ₂ CH ₂ ) _n OH, sorbitan tristearate, where n has an average value of 2), .sosorbidiaurate, and qiyceryl monostearate.

The emulsifier may be included in an amount sufficient to dissolve the immobilizing agent in the plasticizer such that a substantially uniform mixture is achieved. For example, an approximately 1:1 mixture of N-cocoyl-N-methylglucamide and petrolatum, which does not normally melt into a single phase mixture, will melt into a single phase mixture upon the addition of a 20% mixture of a 1:1 mixture of Stearate2 and sorbitan tristearate as emulsifier.

Other types of additives that can be used as immobilizing agents, either alone or in combination with the immobilizing agents mentioned above, include waxes such as carnauba, beeswax, candolilla, paraffin, ceresin, esparto, ouricuri, red wax, isoparaffin, and other known extracted and mineral waxes. The high melting point of these materials can help immobilize the agent on the desired surface or placement on the cuff. In addition, microcrystalline waxes are effective immobilizing agents that can help "lock in" low molecular weight hydrocarbons.

C, Application of skin care product to cuffs {or other structures

In preparing the treated cuff products of the present invention, the skin care composition is preferably applied to the body-facing surface (i.e., wearer-contacting surface) of the cuff. However, since some of the skin care compositions described herein may penetrate or migrate through some of the cuff materials described herein, the skin care composition may alternatively be applied to the garment-facing surface of the cuff so that an effective amount of the skin care composition is also provided on the body-facing surface. In fact, in some cases, this may be the preferred approach to achieving the benefits of a fully treated cuff (i.e.,

The method of application of the composition to the cuffs should be such that the cuffs do not become oversaturated with the skin care composition. If the cuffs are treated with excessive amounts of the skin care composition, there is a greater possibility that the skin care composition will move to undesirable locations in the product, for example, into the interior of the product where it may have

The underlying absorbent core is not required to have a detrimental effect on the absorption of the core. Also, saturation of the cuffs with skin care compositions is not required to achieve the appropriate therapeutic and/or protective benefits.

The minimum level of skin care composition to be applied to the cuff is the smallest amount effective to reduce erythema, diaper rash, red spots, skin irritation or other adverse skin conditions (such compositions or compositions may also be effective in reducing the adhesion of stool (solid exudates) to the wearer's skin.) Of course, the effective amount of skin care composition will depend to a large extent on the particular composition used. Because the emollient is essentially immobilized (immobilized) on the surface of the cuff body, less skin care composition is required to provide the desired skin care benefits. These relatively low levels of skin care composition are adequate for the purpose of providing the desired skin care benefits.

Oldou O 1 . tropeut (u.di morning n vch /hod of desire swept care of the skin

The skin care composition may be applied flat and uniformly to one or both surfaces of the cuff or a portion thereof. The composition may also be applied in a pattern, such as stripes, blocks, dots, spirals, etc. Preferably, the skin care composition will be aligned with that area of the cuff that will be in most contact with the wearer during use. Most preferably, as hereinafter set forth, the skin care composition is applied in a discrete (inconspicuous) strip, for example, 1.4 inches (about 3.55 cm) wide, as described in the Examples, to the lateral portion of the cuff, so that it is covered and maintained;

further from the body, the edge of the cuff) and an 11.75 inch long (about 29.8 cm, in the longitudinal direction of the diaper), patch, generally arranged in the crotch portion of the body-facing surface of the cuff.

The skin care composition may also be applied to one or both surfaces of the cuff unevenly. By unevenly is meant that the amount, distribution pattern, etc., of the skin care composition may vary across the surface of the cuff. For example, certain portions of the treated surface of the cuff may have greater or lesser amounts of the composition, including portions of the composition.

which will not have icin c u on them

The skin care mixture can be applied to the cuff or any structure forming the cuff. The cuff in the barrier assembly at any point. the skin can be. applied to

For example, this composition treats the cuff of a finished product before it is packaged. The composition may also be applied to the cuff or structure before it is combined with other raw materials to form a finished product, either in place before being combined with other product components or as a pre-treated (processed) product.

In applying the skin care compositions of the present invention to the cuffs, slot extrusion, coating, and spray methods are preferred. Fig. 5 illustrates a preferred method comprising continuous or intermittent contact application of the skin care composition to the barrier cuff of the diaper during the finishing operation. Referring to Fig. 5, conveyor belt 1 moves in the direction shown by the arrows on rotating rollers 3 and 4 and becomes a return conveyor belt 2.

At the slot spray station 6, the nonwoven barrier cuff structure 1 becomes a treated barrier cuff structure, designated 3. The treated barrier cuff structure 3 is then guided around a rotating roller 4 and a rotating roller 8 onto a supply roller 10 (rotating in the direction indicated by arrow 10a). This treated structure is then applied to the diaper assembly and forms the barrier portion during the finishing operation. barrier cuff.

D, Product (mixture of care for cuffs and top layer)

As shown in Fig. 7, first, a skin care agent may be disposed on the top layer, and second, a skin care agent may be disposed on one or more cuffs. It has been found that the addition of _a skin care agent to the cuffs, the upper layer, and the treated cuffs provides a larger surface area of skin to which the skin care agent can be transferred. With a larger surface area of skin having the skin care agent transferred thereon, all parts of the wearer's skin are more likely to be maintained in a healthier condition.

As described above, the first skin care product and the second skin care product may have the same composition. However, it has been found that if the first skin care composition is different from the second skin care composition, then the diaper can be designed to provide a specific benefit to the skin at specific locations of the wearer. For example, since the topsheet is typically worn in contact with the wearer's genitals and buttocks, a first skin care composition specifically formulated to provide, for example, protection against diaper rash and/or some treatment, can be arranged on the topsheet. Since the cuffs tend to contact the wearer's waist and legs, the second skin care composition can be specifically formulated, for example, to provide the benefit of reduced chafing/red marks on the skin. Thus, a specific portion of the diaper can have a specifically formulated skin care composition intended for a specific area of the wearer's skin for skin treatment or maintenance. This allows for great flexibility in the design of diapers and the ability of the manufacturer to provide specially designed products for a variety of different consumer needs.

One variation in the compositions of the skin care product may be the result of the function of the elements on which the product is arranged. For example, cuffs are typically designed to contain and limit urine and fecal material flow within the diaper. It may be desirable for the cuffs to be permeable, more specifically, to liquids, to prevent liquids from penetrating certain materials. If the skin care product is also hydrophobic, this may require the cuffs to resist the passage of liquids through them. In contrast, the topsheet needs to be highly permeable to liquids to allow urine and menses to rapidly penetrate the topsheet into the absorbent core. Placing a hydrophobic skin care product on the topsheet may degrade the performance of a particular topsheet. It may be desirable to provide a hydrophilic skin care composition on the topsheet to maintain the performance of the topsheet. Accordingly, in some embodiments, it may be desirable for at least a portion of the skin care composition provided on the topsheet to be made of a hydrophilic material to promote rapid transfer of fluids (e.g., urine) through the topsheet. Similarly, it may be desirable for the skin care composition to also be sufficiently wettable to ensure that fluids are transferred rapidly through the topsheet. Alternatively, a hydrophobic skin care composition may be used, provided that the fluid handling properties of the topsheet are properly maintained. For example, uneven application of the composition to the topsheet is one means of achieving this goal. An example of uneven application is described in U.S. Patent Application Serial No. 08/908,852 (P & G Case 5494CR), entitled Diaper Having a Topsheet Treated with a Skin Surface Treatment Composition, Roe et al.

August 8, 1997, which is incorporated herein by reference.

Where a hydrophilic agent is desired, depending on the particular components used in the composition, there may or may not be a need for a hydrophilic surfactant (or mixture of hydrophilic surfactants) to improve wettability. For example, some immobilizing agents, such as cyclohexyl-N-methoxypropyl glucamide, have

submitted HΊΌ ŽC to be in given mixtures, : n O C . .i í í i a x ci

Hydrophilic agents with HRB values can be added to immobilize the hydrophilic surfactant. Clays such as fatty alcohols having an HRB value of less than about 7 may require the addition of a surfactant to increase wettability when the skin care composition is applied to the topsheet of the diaper. Similarly, hydrophobic emollients such as petrolatum may require additional hydrophilic surfactants for wettability when the wearer is contacting the surface under consideration is not a factor (for example,

Fig. 6 illustrates an alternative preferred method comprising contact slot application of a skin care composition to diaper barrier cuffs before the cuffs are combined with other raw materials into a finished product. Referring to Fig. 6, a nonwoven barrier cuff structure 1 is unwound from a barrier cuff supply roll 2 (by rotation in the direction indicated by arrow 2a) and brought into contact with a slot application station 6 where one side of the structure is coated with a hot, molten (e.g., skin care composition) mixture. At the slot spray station 6, the nonwoven barrier cuff structure 1 becomes a treated barrier cuff structure, designated 3. The treated barrier cuff structure 3 is then guided around a rotating roller 4 and a rotating roller 8 onto a supply roller 10 (rotating in the direction indicated by arrow 10a). This treated structure is then applied to the diaper assembly and forms the barrier portion during the finishing operation. barrier cuff. D, Product (mixture of care for cuffs and top layer) As shown in Fig. 7, first, a skin care agent may be disposed on the top layer, and second, a skin care agent may be disposed on one or more cuffs. It has been found that the addition of _a skin care agent to the cuffs, the upper layer, and the treated cuffs provides a larger surface area of skin to which the skin care agent can be transferred. With a larger surface area of skin having the skin care agent transferred thereon, all parts of the wearer's skin are more likely to be maintained in a healthier condition. • « • 0 · · ··· ·«· As described above, the first skin care product and the second skin care product may have the same composition. However, it has been found that if the first skin care composition is different from the second skin care composition, then the diaper can be designed to provide a specific benefit to the skin at specific locations of the wearer. For example, since the topsheet is typically worn in contact with the wearer's genitals and buttocks, a first skin care composition specifically formulated to provide, for example, protection against diaper rash and/or some treatment, can be arranged on the topsheet. Since the cuffs tend to contact the wearer's waist and legs, the second skin care composition can be specifically formulated, for example, to provide the benefit of reduced chafing/red marks on the skin. Thus, a specific portion of the diaper can have a specifically formulated skin care composition intended for a specific area of the wearer's skin for skin treatment or maintenance. This allows for great flexibility in the design of diapers and the ability of the manufacturer to provide specially designed products for a variety of different consumer needs. One variation in the compositions of the skin care product may be the result of the function of the elements on which the product is arranged. For example, cuffs are typically designed to contain and limit urine and fecal material flow within the diaper. It may be desirable for the cuffs to be permeable, more specifically, to liquids, to prevent liquids from penetrating certain materials. If the skin care product is also hydrophobic, this may require the cuffs to resist the passage of liquids through them. In contrast, the topsheet needs to be highly permeable to liquids to allow urine and menses to rapidly penetrate the topsheet into the absorbent core. Placing a hydrophobic skin care product on the topsheet may degrade the performance of a particular topsheet. It may be desirable to provide a hydrophilic skin care composition on the topsheet to maintain the performance of the topsheet. Accordingly, in some embodiments, it may be desirable for at least a portion of the skin care composition provided on the topsheet to be made of a hydrophilic material to promote rapid transfer of fluids (e.g., urine) through the topsheet. Similarly, it may be desirable for the skin care composition to also be sufficiently wettable to ensure that fluids are transferred rapidly through the topsheet. Alternatively, a hydrophobic skin care composition may be used, provided that the fluid handling properties of the topsheet are properly maintained. For example, uneven application of the composition to the topsheet is one means of achieving this goal. An example of uneven application is described in U.S. Patent Application Serial No. 08/908,852 (P & G Case 5494CR), entitled Diaper Having a Topsheet Treated with a Skin Surface Treatment Composition, Roe et al. August 8, 1997, which is incorporated herein by reference. Where a hydrophilic agent is desired, depending on the particular components used in the composition, there may or may not be a need for a hydrophilic surfactant (or mixture of hydrophilic surfactants) to improve wettability. For example, some immobilizing agents, such as cyclohexyl-N-methoxypropyl glucamide, have submitted HΊΌ ŽC to be in given mixtures, : n O C . .i í í i a x ci Hydrophilic agents with HRB values can be added to immobilize the hydrophilic surfactant. Clays such as fatty alcohols having an HRB value of less than about 7 may require the addition of a surfactant to increase wettability when the skin care composition is applied to the topsheet of the diaper. Similarly, hydrophobic emollients such as petrolatum may require additional hydrophilic surfactants for wettability when the wearer is contacting the surface under consideration is not a factor (for example, Suitable miscible with were created • · 4 4 4 • 4 4 4 4 4 • · · * 4 4 4 4 4 4 4 4« • 444 44 44 · ob: •44 444 when it is desired that the hydrophobic or fluid-handling properties of the material be maintained by other means (non-uniform application). Hydrophilic surfactants are preferably other components of the skin care mixture to prevent the mixed mixture. Because of the possible skin sensitivity of those using disposable diapers, these non-irritating absorbent products to which these surfactants are applied are also undesirable. Typically non-ionic _not only to prevent other effects on the skin, but also to prevent other effects on the skin, such as reducing the tensile strength of the fabric bond and the like. Suitable nonionic surfactants may be substantially immobile when the composition is applied to the diaper topsheet, and will typically have HLB values in the range of from about 4 to about 20, preferably from about 7 to about 20.

The alkyl chain of the aliphatic alcohol is typically in a straight chain configuration (linear) and contains from about 6 to about 22 carbon atoms. Especially preferred are condensation products of alcohols having an alkyl group containing from about 11 to about 22 carbon atoms, with from about 2 to about 30 moles of ethylene oxide per mole of alcohol. Examples of such ethoxylated alcohols include the condensation products of myristic alcohol with 7 moles of ethylene oxide per mole of alcohol, the condensation products of coconut alcohol (a mixture of fatty alcohols having alkyl chains of varying lengths from 10 to 14 carbon atoms) with about 6 moles of ethylene oxide. A number of suitable ethoxylated alcohols are commercially available, for example, TERGITOK 15-3-9 (a condensation product of linear C11-C15 alcohols with 9 moles of ethylene oxide), sold by Union Carbide Corporation; KYRO ROB (a condensation product of linear C13-C15 alcohols with 9 moles of ethylene oxide) sold by The Procter & Gamble Co.; the NEOHOL brand of surfactants sold by Shell Chemical Co., particularly the unandrogenated azo alcohols ty ι J 1 C(0 DOI 012-05 with 12 moles of ethylene oxide) and NEOHOL· 23-6. ST (condensation product of linear alcohols C12-C13 with 6.5 moles of 6.3 ethylene oxide, which has been distilled (atmospheric) to remove certain impurities), and especially the surfactants under the trademark RLURARAC sold by BASE Corp., especially PLURAEAC A-36 (a condensation product of a straight-chain alcohol with 27 moles of ethylene oxide). (Certain hydrophilic surfactants, especially ethoxylated alcohols such as NEOoOL 25-12, can also be tungstic ^1- alkyl ethoxylate plasticizers). Other examples of preferred ethoxylated alcohol surfactants include the Brij class of ICi surfactants and mixtures thereof, with Brij 72 (i.e., Steareth-2) and Brij 76 Which are particularly preferred. As AU ' jOO lJ i (t. Steareth-10), hydrophilic surfactants can also be mixtures of cetyl alcohol and stearyl alcohol, ethoxylated to an average degree of ethoxylation of from about 10 to about 20. Another type of suitable surfactant for use in the present invention includes Aerosol OT, dioctyl sodium sulfosuccinic acid ester, sold by American Cynamid. Company. Still another type of suitable surfactant for use in the present composition includes silicone copolymers such as General Electric 5F 11.88 (a copolymer of polydimethylsiloxane and polyoxyalkylene ether) and General Electric SF 1228 (a silicone polyether copolymer). These silicone surfactants can be used in combination with other types of hydrophilic surfactants discussed above, such as ethyloxy alcohols. These silicone surfactants have been found to be effective at concentrations as low as 0.1%, more preferably from about 0.25 to about 1.0%, by weight of the composition. Where a hydrophilic mixture is desired, the amount of surfactant required to increase the ^{hydrophilicity} of this mixture to the desired level will depend on the Hl.B value and on the level of immobilization used; dla, there are some, HLB value of the surface treatment used agents and similar factors.

Applicants have discovered that maintaining or improving the health of the skin beneath an absorbent article can be achieved by repeatedly using, over a period of time (e.g., several days), absorbent articles treated with two or more skin care agents that are transferred to the wearer under conditions of normal use (e.g., by touch, movement, handling by a caregiver after application, body heat, etc.) such as the absorbent articles described herein. In this regard, a method for maintaining or improving the health of the skin in an area covered by an absorbent article includes the steps of: a) applying to the wearer an absorbent article having a first skin care composition that provides a therapeutic (healing) and/or protective benefit when delivered to the skin and a second skin care composition that provides a second benefit to the skin when delivered thereto, b) transferring to the wearer during wear at least a portion of the first skin care product and the second skin care product, and njnon i er. v y r '3 y K 'improved 1 reflection im vyrot > k θ π i v c repeating steps a) and b) using one or more to maintain or cover the absorbent article in relation to the skin with an equivalent absorbent article that does not include the first and second skin care products, and without the need for manual application, protective skin care products (e.g. by the caregiver or wearer). • »·· Key, /. this method uses an absorbent article having one or more skin care agents and frequent cycles of cumulative (summary, total, note transl.) delivery of the first and second skin care agents to the skin of the wearer to maintain and/or improve the health of his skin. Applicants have further discovered that the delivery of relatively low levels of these agents by wearing each article was sufficient to achieve the skin benefits resulting from this novel cumulative delivery method. The product used in the present methods provides a usable source from which skin care agents are continuously delivered to the skin. As these agents are delivered, they accumulate on the surface of the skin and initiate and maintain a protective action. When the used product is worn out and replaced with a new one, this cycle is repeated for further accumulation of this agent above and then oo would have supplied one or the original product is sucked,. Some of the ingredients for use in the preferred skin care agents are known to penetrate the stratum corneum, or skin layer (e.g., petroiatum, which is preferred for use herein.!).
