Description

CLOTHES FOR CLEANING TREATED WITH EMULSION WATER IN LIPIDS BACKGROUND OF THE INVENTION Technical Field The present invention relates to articles that are useful for cleaning and especially for removing perianal dirt. This invention relates particularly to cleaning cloths similar to wet towels made from carrier substrates treated with a reverse emulsion in a high internal water phase. BACKGROUND OF THE INVENTION The cleaning of the skin is a problem of personal hygiene that can not always be easily solved. Of course, the common procedure of washing the skin with soap and water works well, but sometimes, this can not be done or it is inconvenient to do so. Although water and soap could be used to clean the perianal region after defecation, for example, such a procedure would be extremely heavy. Dry toilet paper products, therefore, are the cleaning products that are generally used after defecation. These dried toilet paper products are usually demonized as "toilet paper" or "toilet paper." Perianal skin is marked by the presence of fine folds and wrinkles (sulci) and hair follicles, which make the perianal region one of the most difficult anatomical areas to clean. During defecation, stool is excreted through the anus and tends to accumulate in hard-to-reach regions, such as around the base of the hair and on the sulci of the skin surface. As fecal matter dehydrates upon exposure to air, or when making contact with an absorbent cleaning implement, such as toilet paper, it adheres more tenaciously to the skin and hair, thereby making the subsequent removal of the Dehydrated dirt remaining, be even more difficult. Failing to remove stool from the anus can have a detrimental effect on personal hygiene. The stool that remains on the skin after cleaning after defecation, has a high bacterial and viral content, has bad odors and is generally dehydrated. These characteristics increase the likelihood of perianal diseases and cause personal discomfort (eg, itching, irritation, chafing, etc.) In addition, residual fecal matter stains the inner break and causes it to emanate from the region of the anus, unpleasant odors. In this way, the consequences of inadequate perianal cleansing are clearly unattractive.For those suffering from anus diseases, such as ani pruritis, hemorrhoids, fissures, cryptitis, or the like, the importance of adequate perianal cleansing has a very important significance Perianal diseases are generally characterized by openings in the skin, through which the bacteria and viruses that are found in the residual fecal matter can easily enter.Those who suffer from diseases of the anus, should, for therefore, achieve a high degree of perianal cleansing after defecation, or take the risk of the probability e that these diseases become more serious with the viruses and bacteria that remain on the skin. At the same time, those who suffer from diseases in the anus, face more severe consequences, caused by insufficient cleaning after defecation, have a greater difficulty to achieve a satisfactory level of removal of dirt. Anus diseases, generally, cause the perianal region to become extremely sensitive and attempts to remove fecal matter from this region, rubbing even with normal pressure, cause pain and can further irritate the skin. Attempts to improve the removal of dirt by increasing the pressure of the rub can result in severe pain. Conversely, attempts to minimize discomfort by reducing pressure result in an increase in the amount of residual fecal material remaining on the skin. Conventional toilet paper products used for cleaning the anus, they are essentially dry, the low density hygienic papers depend exclusively on mechanical processes to remove the fecal material from the perianal skin. These conventional products are rubbed against the perianal skin, usually at a pressure of about 1 psi (7 kilopascals) and basically, scrape or abrade the fecal material of the skin. After the first rubs, the upper portion of the dirt layer is removed because the rubbing process can overcome the cohesive resistances of dirt to dirt, which exist within the fecal material. Therefore, an adhesion of the dirt layer itself with the upper portion of the fecal layer that is being removed is originated and the upper portion of the dirt remains adhered to the perianal skin. The conventional products of toilet paper are absorbent and with each successive rubbing the fecal matter increases its dehidation, causing it to adhere more tenaciously to the skin and perianal hair making its removal extremely difficult. Pressing the toilet paper through the resistance against the perianal skin will remove more of the fecal matter but it is extremely painful for people suffering from diseases of the anus and can excoriate even the normal perianal skin, causing potentially irritation, inflammation, pain, bleeding and infection. In order to improve perianal cleaning, cloths have been developed that are kept in some kind of container and are usually wet in the container containing a moisturizing solution. Examples of such products include wipes that are frequently used to clean babies after bowel movements, and may have other additives in the moisturizing solution to soothe the skin. These towels have a permanent wet resistance, so they can not be rinsed. Also, these prior art wipes can often be too wet to dry the skin and tend to have a "cold" feel. There is also a lack of consistency in terms of moisture content in each of the wipes. Also, perianal cleaning products that can be moistened with dry toilet paper have been used. These moistened toilet paper products have a temporary wet strength, so they can be rinsed. However, the users of these products have to wet the paper, which can be inconvenient. Also, it is difficult to obtain the correct level of moisture in these products. In addition, the temporary wet strength of such products is generally inadequate and needs to be improved. In accordance with the above, it would be desirable to produce perianal cleaning products that: (1) have consistent levels of wetting solution; (2) can have adequate temporary wet strength so that they can be rinsed; (3) have a consistent moisture level, adequate to provide effective cleaning; and (4) remain essentially dry, until they are used for cleaning purposes.

SUMMARY OF THE INVENTION The present invention relates to articles useful for cleaning, and particularly, cleaning cloths similar to wet towels that are especially useful for removing perianal dirt. These items include: A. a transporter; B. a lipid water emulsion applied to the carrier, said emulsion comprising: (1) from about 2 to about 60% of a continuous solidified lipid phase, which comprises a waxy lipid material having a melting point of about 30 ° C or higher; (2) from about 39 to about 97% of an internal phase of water dispersed in the lipid phase; and (3) an effective amount of an emulsifier capable of forming an emulsion when the lipid phase is in a liquid state. The present invention further relates to a solid for manufacturing these articles. This method comprises the steps of: A. forming a lipid water emulsion which comprises: (1) from about 2 to about 60% of a solidified continuous lipid phase, which comprises a waxy lipid material having a melting point of about 30 ° C or older; (2) from about 39 to about 97% of an internal phase of water dispersed in the lipid phase; and (3) an effective amount of an emulsifier capable of forming an emulsion when the lipid phase is in a liquid state. B. applying the emulsion to a conveyor at a temperature high enough for the lipid phase to have a liquid or plastic consistency; C. cool the emulsion applied at a temperature low enough for the lipid phase to solidify.

These items have a number of significant advantages over previous cleaning products, especially when they are in the form of cleaning cloths similar to wet towels to remove perianal dirt. These items release significant amounts of water during use, to achieve a comfortable, more effective cleaning. The continuous lipid phase of the emulsion is fragile enough to break easily, by means of low cut contact (for example, during skin rubbing) to easily release this internal water phase, but strong enough, as to avoid the premature release of the water phase during the rigors of processing. The continuous lipid phase of these articles is also stable enough during storage to avoid significant evaporation of the internal water phase. The properties of resistance to normal tension and the ability to be rinsed from these articles are not adversely affected when treated with the inverse emulsions of the internal high phase of the present invention. As a result, the users of these articles they obtain a comfortable, efficient and humid cleaning, without having to change their normal cleaning habits. In addition to being used for perianal cleaning, these items can be used in many other applications that require water supply, as well as dispersible or water-soluble active ingredients. These include the cleaning of hard surface floors, countertop covers, sinks, bath tubs, toilets and the like, as well as the administration of dispersible or water soluble active pharmaceutical or antimicrobial compositions. These articles can serve multiple functions, for example, highly internal phase reverse emulsion applied to these articles can be formulated to provide cleaning and waxing benefits at the same time when they are used in articles such as furniture, shoes, automobiles, and the like. .

DETAILED DESCRIPTION OF THE INVENTION As used in the present description, the term "comprising" means that the different components, ingredients or steps may be used together in the practice of the present invention. Therefore, the term "comprising" includes the terms "consisting essentially of" and "consisting of", which are more restrictive. All percentages, ratios and proportions used in the present description are by weight unless otherwise specified.

A. Highly Internal Phase Reverse Emulsion Conveyors The carriers useful in the present invention can be a variety of substrate forms. Suitable carrier substrates include woven materials, non-woven materials, foams, sponges, blocks of fibrous material, beads, tassels, films and the like. Particularly preferred substrates for use in the present invention are non-woven type materials. These non-woven substrates can comprise any conventionally designed non-woven sheet or coil having a basis weight, gauge (thickness), absorbency and suitable strength characteristics. Nonwoven substrates can generally be defined as bonded fibrous or filamentary products having a coil structure, in which the fibers or filaments are randomly distributed, as in "air layering" or certain "wet layering" processes ", or with a guidance orientation, as in certain processes of" wet layer formation "or" carded ". The fibers or filaments of said substrates can be natural (for example, wood pulp, wool, silk, jute, hemp, cotton, linen, henequen, etc.) or synthetic (for example, rayon, cellulose ester, polyvinyl derivatives, polyolefins, polyamides or polyesters) and can be bonded together with a linking polymeric queen. Examples of suitable commercially available nonwoven substrates include those marketed under the trade names of Sontara® by DuPont and Poly eb® by James River Corporation. For reasons of cost, ease of manufacture, and availability (e.g., rinsing ability), the preferred type of non-woven substrate used in the wipes of the present invention comprises those! made of wood pulp fibers, for example, paper rolls. As can be seen, the paper rolls can be prepared by techniques, either layering by air or wet layering. Paper coils, formed in layers by air, such as Air Tex® SC I 30 are on the market marketed by James River Corp. The most conventional methods for manufacturing paper coils, are the wet layering procedures . In such processes, a coil is made by forming an aqueous material for the manufacture of the paper, depositing this material on a foraminous surface, such as a Fourdrinier strip, and then extracting the water from the material, for example, by gravity, by means of vacuum assisted by drying and / or by evaporation, with or without pressing, to thereby form a paper reel of the desired fiber consistency. In many cases, the papermaking apparatus is prepared to rearrange the fibers in the pulp of the papermaking material, such as dewatering processes, in order to form paper substrates with strength, maneuverability, volume, appearance, absorbency, etc. , especially desired. The papermaking material used to form the preferred paper roll substrates for the articles of the present invention essentially comprise an aqueous pulp of papermaking fibers (eg, paper pulp) and may optionally contain a Wide variety of chemicals such as wet strength resins, surfactants, pH controlling agents, softness additives, release agents and the like. The pulp of wood in all its varieties can be used to form the material for the manufacture of paper. The wood pulps useful in the present disclosure include both sulphite and sulfate pulps, as well as mechanical, thermo-mechanical and chemo-thermo-mechanical pulps, all of which are well known to those skilled in the art of manufacturing paper. Pulps derived from both deciduous and coniferous trees can be used. Preferably, the papermaking material used to form the preferred paper roll substrates for the cloths of the present invention comprises Kraft pulp derived from Nordic softwoods. A number of papermaking processes have been developed, which use a papermaking apparatus that forms paper reels that have particularly useful or desirable fiber configurations. Such configurations can serve to impart such characteristics to the paper reel as increased volume, absorbency and strength. One such process employs a printing material in the papermaking process, which serves to impart a knot pattern in the high density and low density areas within the reaming paper roll. A process of this type and the papermaking apparatus for carrying out this process are described in greater detail in U.S. Patent No. 3,301,746 (Sanford and Associates), issued January 31, 1967, which it is incorporated in the present description as a reference. Another process for papermaking, which is carried out with a special apparatus for papermaking, is one that produces a paper reel having a continuous, different network region, formed by a plurality of scattered "domes". in the entire region of the network on the structure. Said domes are formed by compressing an embryo coil formed during the papermaking process within a foraminous deviation member having a surface with a network pattern formed by a plurality of isolated deviating conduits spaced on the surface of the deviation member. A process of this type, and an apparatus for carrying out said process, are described in greater detail in U.S. Patent No. 4,259,480 (Trokhan), issued July 16, 1985, U.S. Patent No. 4,637,859 (Trokhan ), issued January 20, 1987 and United States Patent No. 5,073, 235 (Trokhan), issued December 17, 1991, all incorporated herein by reference. Another type of papermaking process and apparatus, which can be used and is suitable for making paper substrates with composite layers, is disclosed in U.S. Patent No. 3,994,771 (Morgan et al.), Issued November 30, 1976, which is incorporated in the present description as a reference. Preferred paper web substrates can be formed by two or more layers that can be laminated together. Lamination and lamination performed in combination with an etching process, to form a plurality of protrusions in the laminated product, are described in greater detail in U.S. Patent No. 3,414,459 (Wells), issued December 3, 1968 , which is incorporated herein by reference. These paper substrates preferably have a basis weight of between about 10 g / cm2 and about 65 g / cm2, and a density of about 0.6 g / cc or less. More preferably, the basis weight will be about 40 g / cm 2 or less and the density may be about 0.3 g / cc or less. Even more preferably, the density will be between about 0.04 g / cc and about 0.2 g / cc. See column 13, lines 61 to 67, of US Patent No. 5, 059,282 (Ampulski et al.), Issued October 22, 1991, which describes the way in which the density of toilet paper is measured. (Unless otherwise specified, all amounts and weights related to paper roll substrates are on a dry basis). In addition to papermaking fibers, the papermaking material used to make these paper coil substrates may have other components or materials adhered thereto as may or may be known in the art. The types of desirable additives will depend on the particular end use contemplated for the sheet of toilet paper. For example, in rubbing products, such as toilet paper, paper towels, facial tissues, baby wipes and other similar products, a desirable attribute is a wet wet resistance. Thus, it is often desirable to add to the material for papermaking, chemicals known in the art, such as "wet strength" resins. A general dissertation of the types of wet strength resins used in the art of papermaking can be found in the monograph TAPPI Series No. 29, Wet Strength in Paper and Paperboard, Technical Association of the Pulp and Paper Industry (New York, 1965). The most useful wet strength resins have generally been cationic in nature. For the generation of permanent wet strength, the polyamide-epichlorohydrin resins are cationic wet strength resins, which have been found to be of particular utility. Suitable types of such resins are disclosed in U.S. Patent No. 3, 700,623 (Kein), issued October 24, 1972 and U.S. Patent No. 3,772,076 (Keim) issued November 13, 1973, both of which are incorporated herein by reference. the present description as a reference. A commercial source of a useful polyamide-epichlorohydrin resin is Hercules, Inc., of Wilmington, Delaware, which markets resins, such as the resins of the trademark Kymene® 557H. It has also been found that polyacrylamide resins are useful as wet strength resins. These resins are described in U.S. Patent No. 3,556,932 (Coscia et associates), issued January 19, 1991 and U.S. Patent No. 3,556,933 (Williams et al.), Issued January 19, 1971, both incorporated into the present description as reference. A commercial source for polyacrylamide resins is American Cyanamid Co., of Stamford, Connecticut, which markets one of these resins under the Parez® 631 NC brand. Still other water-soluble cationic resins which have been found to be useful wet strength resins are the resins of urea formaldehyde and melamine formaldehyde. The most common functional groups of these polyfunctional resins are nitrogen-containing groups, such as amino groups and methylol t groups bonded to nitrogen. Resins of the polyethylenimine type may also be useful in the present invention. In addition, temporary wet strength resins, such as Caldas 10 (manufactured by Japan Carlit) and CoBond 1000 (manufactured by National Starch and Chemical Company) can be used in the present invention. It should be understood that the addition to the papermaking material of chemical compounds, such as wet strength resins and temporary wet strength resins referred to above, is optional and is not necessary for the practice of present invention. In addition to wet strength additives, it may also be desirable to include certain dry strength and fray control additives known in the art in the paper manufacure fibers. In this regard, it has been found that starch binders are particularly suitable. In addition to reducing the unraveling of the paper substrate, low levels of starch binders also impart a modest improvement in dry tensile strength, without imparting the hardness that could result from the addition of high levels of starch. Generally, the starch linker is included in an amount such that it is retained at a level of from about 0.01 to about 2%, preferably from about 0. 1 to about 1%, by weight of the paper substrate. In general, starch binders suitable for these paper web substrates are characterized by solubility and hydrophilicity. Although it is not intended to limit the scope of suitable starch linkers, representative starch materials include corn starch and potato starch, with waxy corn starch known industrially as amioca starch being preferred. Amioca starch differs from common corn starch in that it contains only amylopectin, while corn starch contains both amylopectin and amylose. The different exclusive characteristics of amioca starch are described more fully in "Amioca - The Starch From Waxy Corn" by H. H. Schopmeyer, Food Industries, December 1945, pages 106 to 108 (Vol. Pages 1476 to 1478). The starch linker may be in granular or dispersed form, the granular form being especially preferred. The starch linker is preferably sufficiently cooked, as to induce the inflammation of the granules. More preferably, the starch granules are ignited, as by cooking, to a point just before the starch granule dispersion. To said highly inflamed starch granules we will refer to them as "fully cooked". The conditions for dispersion, in general, can vary depending on the size of the starch granules, the degree of crystallinity of the granules, and the amount of amylose present. The fully cooked amioca starch, for example, can be prepared by heating an aqueous paste with a consistency of approximately 4% starch granules at a temperature of about 190 ° F (about 88 ° C) for a period of time between about 30 and approximately 40 minutes. Other exemplary starch linkers that may be used include modified cationic starches, such as those modified to have nitrogen group content, including amino groups and methylol groups bonded to nitrogen, marketed by National Starch and Chemical Company, (Bridgewater , New Jersey), which have previously been used as additives to the pulp of the material to increase wet and / or dry strength.

B. Highly Internal Phase Reverse Emulsion Composition The articles of the present invention comprise an emulsion of water in lipids that is applied to a carrier substrate. The emulsion comprises: (1) a continuous solidified lipid phase; (2) an emulsifier that forms a water emulsion in lipids when the lipid phase is liquid; and (3) an internal phase of water dispersed in the lipid phase. Since the internal phase contains a high level of water, this emulsion is generally referred to as a "highly internal phase reverse emulsion". This highly internal phase reverse emulsion is broken when subjected to low cutting during use, for example, by rubbing with the skin or other surface, such as to release the internal water phase.

The continuous solidified lipid phase provides the essential stabilizing structure for the highly internal phase reverse emulsions of the present invention. In particular, this continuous lipid phase is that which retains the dispersed internal water phase, so that it is not released prematurely before use. of the article, as in the rigors of processing.

The continuous lipid phase may comprise from about 2 to about 60% of the emulsion of the present invention. Preferably, this continuous lipid phase will comprise from about 5 to about 30% of the emulsion. Even more preferably, this lipid phase will comprise from about 6 to about 15% of the emulsion. The main constituent of this continuous lipid phase is a waxy lipid material. This lipid material is characterized by a melting point of about 30 ° C or higher, for example, it is solid at ambient temperatures. Preferably, this lipid material has a melting point of about 50 ° C or higher. Generally, this lipid material has a melting point in the range of from about 40 ° to about 80 ° C, more typically in the range of from about 60 ° to about 70 ° C. Although this waxy lipid material is solid at room temperatures , it also needs to be liquid or plastic at those temperatures at which the inverse phase emulsion highly internal to the carrier substrate is applied. In addition, although this lipid material is liquid or plastic at those temperatures at which the emulsion is applied to the carrier substrate, it would still be desirable for it to be somewhat stable (for example, not to melt) for extended periods of time at elevated temperatures (eg. example, approximately 50 ° C or greater) that are normally concentrated during storage and distribution of the articles of the present invention. This lipid material also needs to be sufficiently fragile to the cutting conditions of the use of this article, so that it breaks and releases the internal dispersed water phase. It is also desirable that these lipid materials provide a good feeling to the skin when they are used in products for e! personal care, such as cleaning cloths similar to wet towels used in perianal cleaning. Waxy lipid materials suitable for use in the highly internal phase reverse emulsion of the present invention include natural and synthetic waxes, as well as other oil-soluble materials having a waxy consistency. As used herein the term "waxes" refers to mixtures or organic compounds that are generally insoluble in water and tend to exist as amorphous or microcrystalline solids at room temperatures (eg, at about 25 ° C). Suitable waxes include various types of hydrocarbons, as well as esters of certain fatty acids and fatty alcohols. These can be derived from natural sources (for example, animals, vegetables or minerals) or can be synthesized. Mixtures of various waxes can also be used. Some of the representative animal and vegetable waxes that can be used in the present invention, include beeswax, carnauba, spermaceti, lanolin, lacquer wax, candelilla and the like. Particularly preferred animal and vegetable waxes are beeswax, lanolin and candelilla. Waxes representative of the mineral sources that may be used in the present invention include petroleum-based waxes, such as paraffin, petrolatum and microcrystalline wax, and fossil or earth waxes, such as white, ceresin wax, yellow ceresin wax , white oxokerite wax and the like. Particularly preferred mineral waxes are petrolatum, microcrystalline wax, yellow ceresin wax and ozokerite white wax. Representative synthetic waxes that can be used in the present invention include ethylenic polymers, such as polyethylene wax, chlorinated naphthalenes such as "Halowax", hydrocarbon type waxes manufactured by means of the Fischer-Tropsch synthesis and the like. Particularly preferred synthetic waxes are polyethylene waxes. In addition to the waxy lipid material, the continuous lipid phase may include minor amounts of other lipophilic or lipid miscible materials. These other lipophilic / lipid miscible materials are usually included for the purpose of stabilizing the emulsion to minimize water loss or improve the aesthetic feel of the emulsion on the skin. Suitable materials of this type that may be present in the continuous lipid phase include heat-melted adhesives, such as Findley 193-336 resin, long chain alcohols such as cetyl alcohol, stearyl alcohol and cetarilic alcohol, water insoluble soaps such as aluminum stearate, silicone polymers such as polydimethylsiloxanes, hydrophobically modified silicone polymers, such as phenyl trimethicone, and the like. The main component of these highly internal phase reverse emulsions of the present invention is the dispersed internal water phase. This water phase can produce a number of different benefits when it is released. For example, in cleaning cloths similar to wet towels, preferred for perianal cleaning, this internal phase of released water is what produces the main cleaning action for these cloths. In other products, this internally released phase can be used to administer a variety of active components soluble or dispersible in water. The internal water phase may comprise from about 39 to about 97% of the cleaning component of the present invention. Preferably, this internal water phase will comprise from about 67 to about 92% of the cleaning component. Even more preferably, this water phase will comprise from about 82 to about 91% of the cleaning component. In addition to water, this internal water phase may comprise other water soluble or dispersible materials, which do not adversely affect the stability of the highly internal phase reverse emulsion. One of these materials that is generally included in the internal phase of water are water-soluble electrolytes. The dissolved electrolytes minimize the tendency of the materials present in the lipid phase to also dissolve in the water phase. Any electrolyte capable of imparting ionic strength to the water phase can be used. Suitable electrolytes include the water-soluble mono-, di- or trivalent inorganic salts, such as the water-soluble halides, for example, chlorides, nitrates and sulfates of alkali metals and alkaline earth metals. Examples of such electrolytes include sodium chloride, calcium chloride, sodium sulfate, magnesium sulfate, and sodium bicarbonate. The electrolyte will generally be included in a concentration in the range of from about 1 to about 20% of the water phase.

Other soluble or water dispersible materials that may be present in the internal water phase include thickeners and viscosity modifiers. Suitable thickeners and viscosity modifiers include polyacrylic resins and hydrophobically modified water-soluble polyacrylic resins, such as Carbopol and Pemulen, starches, such as corn starch, potato starch, tapioca, gums, such as guar gum, gum arabic, cellulose ethers such as hydroxypropyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose and the like. These thickeners and viscosity modifiers will generally be included in a concentration in the range of from about 0.05 to about 0.5% of the guide phase. Other water soluble or dispersible materials that may be present in the internal water phase include polycationic polymers that provide steric stabilization at the water-lipid interface and nonionic polymers that also stabilize the water emulsion in lipids. Suitable polycationic polymers include Reten 201, Kymene® 557H and Acco 7 1 1. Suitable nonionic polymers include polyethylene glycols (PEG) such as Carbowax. These polycationic and nonionic polymers will generally be included in a concentration in the range of from about 0. 1 to about 1.0% of the water content. Another key component of the highly internal phase reverse emulsion of the present invention is an emulsifier. In the emulsions of the present invention, the emulsifier is included in an effective amount. What constitutes an "effective amount" will depend on a number of factors including the respective amounts of the components of the lipid and oil phase, the type of emulsifier used, the level of impurities present in the emulsifier, and the like. Generally, the emulsifier comprises from about 1 to about 10% of the emulsion. Preferably, this emulsifier will comprise from about 3 to about 6% of the emulsion. Even more preferably, this emulsifier will comprise from about 4 to about 5% of the emulsion. This emulsifier needs to be substantially soluble in the lipid or miscible with the materials of the lipid phase, especially at the temperatures at which the lipid material melts. It must also have a relatively low HLB value. Emulsifiers suitable for use in the present invention have HLB values generally in the range of from about 2 to about 5 and may include mixtures of different emulsifiers. Preferably, these emulsifiers will have HLB values in the range of from about 2.5 to about 3.5. Emulsifiers suitable for use in the present invention include certain sorbitan esters, preferably sorbitan esters of saturated C 1 to C 22 fatty acids, unsaturated branched chain. Due to the manner in which they are generally manufactured, these sorbitan esters usually comprise mixtures of mono-, di-, triesters, etc. Representative examples of suitable sorbitan esters include sorbitan monooleate (e.g., SPAN® 80), sorbitan sesquioleate (e.g., Arlacel® 83), sorbitan monoisostearate (e.g., CRILL® 6 manufactured by Croda), stearates of sorbitan (for example SPAN® 60), sorbitan trioleate (for example SPAN® 85), sorbitan tristearate (for example, SPAN® 65) and sorbitan dipalmitates (for example, SPAN® 40). The sorbitan monoisostearate and sorbitan sesquileate are the particularly preferred emulsifiers for use in the present invention. Other emulsifiers suitable for use in the present invention include certain glyceryl monoesters, preferably glyceryl monoesters of saturated C, C to C22 saturated, unsaturated branched chain fatty acids, such as glyceryl monostearate, glyceryl monopalmitate and glyceryl monobehenate.; certain fatty acid sucrose esters, preferably the sucrose esters of saturated, unsaturated and branched chain C 12 to C 22 fatty acids, such as sucrose trilaurate and sucrose distearate (for example Crodesta® FIO), and certain esters polyglycerol fatty acids from C to C22, saturated, unsaturated or branched chain, such as diglycerol monooleate and tetraglycerol monooleate. In addition to these major emulsifiers, co-emulsifiers can be used to produce additional stability to the water-in-lipid emulsion. Suitable co-emulsifiers include choline phosphatidyl and compositions containing choline phosphatidyl, such as lecithins; the long chain C C to C22 fatty acid salts, such as sodium stearate, dialiphatic quaternary ammonium salts of long chain C C to C22, and short chain C ia C 4, such as ammonium chloride differed dimethyl dimethyl dimethyl ammonium methylsulfate; dialcoyl (alkenoyl) -2-hydroxyethyl from Cie to C22 long chain and dialiphatic quaternary ammonium salts of short chain C a C4, such as ammonium ditallowyl-2-hydroxyethyl dimethyl chloride, the dialkylamide imidazolinium quaternary ammonium salts of C i 6 to C22 of long chain, such as methylsulphate methyl-1-tallowamido ethyl 2-2 tallow imidazolinium and methylsulphate methyl-2-oleyl amido ethyl-2-oleyl imidazolinium; the monoaliphatic benzyl quaternary ammonium salts of long chain C i6 to C22, such as ammonium dimethyl stearyl benzyl chloride and synthetic phospholipids such as stearamidopropyl PG-dimonium chloride (Phospholipid PTS from Mona Industries). You can also use voltage modifiers at the interfaces, such as cetyl or stearyl alcohol to pack them closer at the water-lipid interface. The highly internal phase reverse emulsions of the present invention may also comprise other optional components, generally present in solutions containing such moisture. These optional components may be present, either in the continuous lipid phase or in the internal phase of water and include perfumes, antimicrobial (antibacterial) active compounds, active pharmaceutical compounds, deodorants, opacifiers, astringents, skin moisturizers, and the like, as well as mixtures of these components. All of these materials are well known in the art as additives to such formulations and can be employed in appropriate effective amounts in the emulsions of the present invention. A particularly preferred optional component that is included in the emulsions of the wipes similar to the wipes in accordance with the present invention, is glycerin as a skin conditioning agent.

C. Other Optional Cloth Components In addition to the highly internal phase reverse emulsion, there are other optional components that can be included in the articles of the present invention, generally for the purpose of improving the cleaning performance of the article when the phase is released. internal water emulsion. Some of these optional components can not be present in the emulsion at significant levels (eg, greater than 2% of the internal water phase) because they can cause premature breakdown of the emulsion. These include various anionic detergent surfactants having relatively low HLB values (e.g., HLB values of from about 10 to about 25), such as linear sodium alkylbenzene sulfonates (LAS) or alkyl ethoxy sulfates (AES), as well as non-detergent surfactants. ionics, such as alkyl ethoxylates, amino alkyl oxides, alkyl polyglycosides, detergent surfactants, ampholytic detergent surfactants and cationic detergent surfactants, such as cetyl trimethyl ammonium salts, and lauryl trimethyl ammonium salts. See U.S. Patent No. 4,597,898 (Vander Meer), issued July 1, 1986 (incorporated herein by reference), especially columns 12 through 16 to see anionic, nonionic, switerionic, ampholytic, and detergent surfactants. representative cationics, Instead of them, these detergent surfactants with high HLB values can be applied or included in the separate article of the emulsion. For example, an aqueous solution of these detergent surfactants with high HLB values can be applied to one side of the carrier substrate, the inverse emulsion of highly internal phase being applied to the other side of the substrate. During rubbing, the emulsion is broken, releasing the water so that it can then be combined with detergent surfactants of high HLB values to improve the cleaning of the hard surface.

D. Preparation of the Emulsion-treated Articles In the preparation of the articles according to the present invention, the inverse emulsion is initially formulated with water phase in highly internal lipids. Generally, this is accomplished either by mixing or by melting together the components of the lipid phase and the emulsifier. The particular temperature at which this lipid / emulsifier mixture is heated will depend on the melting point of the lipid phase. Generally, this lipid / emulsifier mixture is heated to a temperature in the range of from about 60 ° to about 90 ° C, preferably from about 70 ° to about 80 ° C before being mixed, melted or combined in some other way with the components of the water phase. The melted lipid / emulsifier mixture is then mixed with the components of the water phase and then mixed together, generally, under low cut conditions to produce the emulsion. This highly internal phase reverse emulsion is then applied to the carrier substrate, in a liquid or plastic state at the temperatures indicated above, for example, a paper roll. For the application of this emulsion a variety of application methods can be used that distribute in an equitable manner, the materials that have a liquid or plastic consistency. Suitable methods include spraying, printing (eg, flexographic or colander printing), coating (eg etching coating), extrusion or combinations of these application techniques, for example, by spraying the detergent surfactant onto the paper coil, followed by by the engraved coating of the emulsion on the coil treated with the detergent. The emulsion can be applied either on one side or on both sides of the paper reel, or in the case of multiple layer reels, it can be applied on the inner surfaces of the layers. For example, in the case of a two-layer paper roll, the emulsion can be applied to at least one of the inner surfaces of the opposed layers, leaving the outer surfaces of the paper roll free of the emulsion. Generally, the emulsion is applied on both sides of the paper roll. The application of the emulsion on both sides of the coil can be either consecutively or simultaneously. Once the emulsion has been applied to the paper roll, it is allowed to cool and solidify to form a generally discontinuous solidified coating or film on the surface of the roll. The highly internal phase reverse emulsion is generally applied to the paper coil, after the coil has been dried, for example, an addition method to a "dry coil". The emulsion can be applied so that it is not uniform to the surfaces of the coil. By "non-uniform" we mean that the quantity, pattern of distribution, etc. , of the emulsion may vary on the surface of the paper roll. For example, some portions of the surface of the paper roll may have greater or lesser amounts of the emulsion, including portions of the surface that do not contain emulsion. The highly internal phase reverse emulsion can be applied to the paper roll at any time after it has been dried. For example, the emulsion can be applied to the paper roll after it has been slid from a Yankee dryer. Normally, it is preferred to apply the emulsion to the paper roll as it is being unrolled from a main roll and before being wound onto the rolls of finished products that are smaller. In the application of the highly internal phase reverse emulsions of the present invention to paper rolls, spraying or etching methods are generally preferred. Figure 1 illustrates one of said preferred methods wherein the emulsion is sprayed onto the paper coil 10. Referring to Figure 1, this spray system has a spray nozzle 12 which applies a dispersed spray 14 of the emulsion on the coil 10. This spray system is operated by an assembly consisting of a ball screwdriver 16 which is connected by the copy 18 to a plunger 26 of the hydraulic cylinder 22. A portion of the cylinder 22 is shown in Figure 1 as if was filled with the highly internal phase reverse emulsion as indicated by number 20. Cylinder 22 is heated to maintain emulsion 30 in a liquid or plastic condition. The emulsion 30 enters the cylinder 22 by means of a four-way copy 34 having a line 38 connected to the heated filling port 42. The copy 34 also has a line 46 which is connected to a pressure gauge 50 and the nozzle sprinkler 12. There are three valves indicated as 56, 58, and 60 that control the flow of the emulsion on lines 38 and 46. The sprinkler system shown in Figure 2 also has a line 64 connected to the spray nozzle 12 that allows that the air indicated generally with the number 68 is admitted to the spray head. Line 64 also has a pressure gauge and regulator 72 for controlling and measuring the air pressure in the line. Lines 64 and 46 are heated to maintain the emulsion in a melted state prior to application to the coil. To fill the cylinder 22 with the emulsion 30, the valves 56 and 60 are closed and the valve 58 is opened. The ball screwdriver 16 is activated so that the plunger 26 moves to the left. The vacuum created in the cylinder 22 drives the emulsion from the filling port 46 through the line 38 and into the cylinder 22. To absent the emulsion from the cylinder 22 to the spray nozzle 12, the valve 58 is closed and the valves 56 and 60 are open. The ball screwdriver 16 is actuated so that the plunger 26 moves to the right. This fools the emulsion 30 out of the cylinder 22 and into the line 46 of the copy 34. The emulsion then passes through the valve 60 and into the spray nozzle 12 where it is dispersed for the incorporation of air from line 64 to supply the dispersed spray 14 which is then applied to the coil 10. Figure 2 illustrates an alternative method for the application of the highly internal phase reverse emulsion, which comprises a flexible rotogravure coating system. With reference to Figure 2, a paper roll 1 10 is unwound from the main paper roll 1 12 (which rotates in the direction indicated by the arrow 1 12a) and rolled up by turning the rolls 1 14, 1 16 and 1 18. From roller 1 18, coil 1 10 is advanced to an engraving coating station indicated generally with the number 120 where the emulsion is then applied on both sides of the coil. After leaving the station 120, the reel 1 10 becomes a treated reel, indicated by the 122. The processed reel 122 is advanced to a surface winder roller 126 (rotating in the direction indicated by the felt 126a) and then it is wound on the finished product roll 128 (which rotates in the direction indicated by arrow 128a). The station 120 comprises a pair of loosely linked engraving presses 130 and 134, The press 130 consists of a smaller anilox cylinder 138 and a larger plate printing cylinder 142.; the press 134 consists similarly of a smaller anilox cylinder and a larger plate printing cylinder 150. The anilox cylinders 138 and 146 each have a ceramic or chrome surface, while the plate printing cylinders 142 and 160 have each one a surface with an embossed pattern of rubber, urethane or photopolymer. These anilox cylinders and plate printers rotate in the directions indicated by the arrows 138a, 142a, 146a and 150a, respectively. As illustrated in Figure 2, the plate printing cylinders 142 and 150 are positioned opposite one another to provide a nip area indicated by the 154 through which the coil 1 10 passes. The hot, melted emulsion (for example, at 60 ° C) is pumped to or sprayed onto each of these linked engraving presses 130 and 134 in the constriction areas indicated by arrows 158 and 162, respectively, in a constant volumetric flow range. In other words, the emulsion is added to the linked engraving presses 130 and 134 in the same range as the emulsion is being applied to the coil 1 10. This eliminates the "accumulation" of the emulsion in the system. As the anilox rolls 138 and 146 rotate in the directions indicated by arrows 138a and 146a, they act as rotating scalpels to evenly spread the emulsion on all surfaces of plate printing cylinders 142 and 150, respectively, and to remove the excess emulsion of the printing plates of the cylinders 142 and 150. The emulsion which is spread on the plate printing cylinders 142 and 150 (which rotate in the opposite direction to that indicated by the arrows 142a and 150b) is then transferred to both sides of the coil 1 10 in the constriction area 154. The amount of emulsion transferred to the coil 1 10 can be controlled by means of: (1) adjusting the width of the constriction area 154 between the printing plate cylinders 142 and 150; (2) adjusting the width of the constricting areas 158 and 162 between the pairs of anilox / printing plate cylinders 138/142 and 146/150; (3) the printing relief of the image (eg, valley depth) of the printing plate on the cylinders 142 and 150; (4) the printed area (e.g., the valley area) of the printing plate on the cylinders 142 and 150; M and / or (6) the printing pattern of the printing plate on the cylinders 142 and 150.

SPECIFIC ILLUSTRATIONS OF THE PREPARATION OF THE CLOTHES FOR CLEANING. SIMILAR TO THE HUMID TOWELS, ACCORDING TO THE PRESENT INVENTION The following are specific illustrations of the preparation of the wipes for cleaning, similar to the wet wipes, according to the present invention, by means of the treatment of rolls of toilet paper with inverse emulsions of water in highly internal phase lipids: Example 1 A). Preparation of the Emulsion A water-in-lipid emulsion is prepared from the following ingredients shown in Table I: Table I In the formulation of the aqueous phase component, sodium chloride and Dantogard are added to the distilled water and then heated to a temperature of 160 ° F (71.1 ° C) .The remaining ingredients of the lipid phase Yellow Cersin, Petrolatum and Crill® 6) are heated, with mixing at a temperature of ~ 170 ° F (76.7 ° C) until they are melted.The components of the water phase and the lipid phase are then combined in a container of stainless steel and mixed with a Hobart Model 100-C mixer at low speed while allowing the ingredients to cool slowly.The mixing continues until the water emulsion forms in lipids.The formation of the emulsion is evident by an increase in the viscosity above 2000 centipoises measured with a rotary disk viscometer Lab-Line Instruments.

B. Application of the Emulsion to the Substrate The emulsion can be applied to the paper coil using the spray system shown in Figure 1. The emulsion is heated to a temperature of 60 ° C so that it is liquid or melted. The ball screwdriver 16 moves at a linear speed of 0.002 in./sec as the plunger 26 operates (3.5 inches in diameter) to push the emulsion out of the cylinder 22 (emulsion pressure at approximately 12 psig). The emulsion enters the spray nozzle 12 (external mixing spray head with SUE 15 preparation from Spray Systems Inc., Wheaton, Illinois) and is dispersed in the air (at 1.2 psig) heated to approximately 60 ° C. The emulsion is applied then from the nozzle 12 as a spray dispersed to the coil while the coil is rewound at approximately 28 feet / minute. For example, the spool can be sprayed at the constriction between a winder roller and the finished product roll (such as the constriction between the surface winder roll 126 and the main finished product roll 128 illustrated in FIG. 2). As a result, the emulsion covers both sides of the coil in an approximately 50% addition. The emulsion can also be applied to the substrate of the paper reel using a flexible rotogravure coating system shown in Figure 2. The hot melted emulsion (eg at 60 ° C) is pumped into, or sprayed onto, each of these presses Engraving patterns 130 and 134 in the areas of narrowing indicated by arrows 158 and 162, respectively in a constant volumetric flow rate of 20 ml / min. The anilox cylinders 138 and 146 spread the emulsion in a balanced manner on all surfaces of the plate printing cylinders 142 and 150, respectively (each rotating at a speed of about 40 feet / minute). Cylinders 142 and 150 then transfer the emulsion to both sides of coil 1 10. Coated coil 122 is transferred to surface coiler 126, so that the coiled central width of coil 122 is over the compressed printed area of the coil 126, while the ends of the coil 122 that are not coated are in contact with the surface of the roller 126. The coil 122 is wound on the finished product roll 128. The emulsion covers both sides of the coil 122 in an adhesion of approximately 50%.
