Description

TREAT SOFT TREATMENT Background of the Invention Absorbent tissue products such as facial tissue and bath tissue have been used to absorb body fluids and leave skin dry. Absorbent tissues, in addition to absorbing fluids, however, have also scraped or pinked the skin. In particular, during frequent nose blowing, the skin is rubbed up to appear red and injured or sensitive to touch. To reduce skin galling, the tissue additive formulations can be applied to the tissue such as, in use, the additive formula that provides lubricity by causing the tissue to slip through the surface of the skin or leave the tissue and deposit on the skin.

To date, these formulas have been semi-solid liquids at room temperature to allow them to be easily deposited on the tissue. A greater amount of these liquids is required to be deposited on the tissue to deliver the benefit of reduced skin redness and irritation because these liquids are absorbed into the tissue, leaving less on the surface to provide the benefit.

Therefore, there is a need for a formula that can be applied to tissue that remains readily available for transfer to the wearer's skin to reduce skin irritation and redness in a cost-effective and efficient manner.

Synthesis of the Invention It has now been discovered that the superior soft tissue product can be made by applying, on the surface of the tissue, large quantities of individual deposits of a melted protective / moisturizing composition comprising a wax and an oil, and then resolidifying the composition to form a distribution. , preferably a uniform distribution of solid deposits on the surface or surfaces of the tissue. Because the composition is a solid at room temperature and solidifies rapidly after deposit, it has a lower tendency to penetrate and migrate into the sheet. Compared to tissues treated with liquid formulas, it leaves a greater percentage of the aggregate composition on the surface of the tissue where it can make contact and transfer to the user's skin to provide the benefit. In addition, a lower aggregate amount can be used to deliver the same benefit at a lower cost due to the efficient placement of the composition essentially on the surface of the product.

Thus, in one aspect the invention resides a tissue product having one or more layers wherein one or both of the outer surfaces of the product have uniformly distributed solidified deposits of a composition ranging from about 30 to about 90 percent. per weight of oil, and from about 10 to about 40 weight percent of wax, preferably also containing from about 5 to about 40 weight percent fatty alcohol, said composition having a melting point of from around 30 degrees centigrade to around 70 degrees centigrade, more specifically from around 40 degrees centigrade to around 60 degrees centigrade. For the purposes given here, the "melted" point is the temperature at which most of the melted occurs, recognizing that the melt currently occurs over a range of temperatures.

In another aspect, the invention resides in a method for making a soft tissue product comprising: (a) heating a composition comprising an oil, a wax, and preferably a fatty alcohol, at a temperature above the melting point of the composition, causing the composition to melt, said composition having a melting point of from about 30 degrees centigrade to about 70 degrees centigrade; (b) uniformly applying the melted composition to one or both surfaces of the tissue tissue in spaced and spaced tanks; and (c) resolidify the deposits of the melted composition. The resolidification of the deposits can occur almost instantaneously, without the need for external cooling means such as the cooling rollers, if the composition is heated to a temperature only slightly above or at the melting point of the composition. However, external cooling means such as the cooling rollers, either before or after the application of the melt, can be used if desired to accelerate the resolidification. Such instant resolidification tends to impede the penetration of the composition into the tissue and to retain it on the surface of the tissue which is advantageous. For example, the temperature of the melted composition may advantageously be above the melting point of about 10 degrees centigrade or less, more specifically about 5 degrees centigrade or less, and even more specifically about 2 degrees centigrade or less. Upon approaching the temperature of the melted composition to the melting point, the viscosity of the melted composition generally increases, which further improves the tendency of the melted composition to be retained on the surface.

The amount of oil in the composition can be from about 30 to about 90 percent by weight, more specifically from about 40 to about 70 percent by weight, and even more specifically from about 45 to about of 60 percent by weight. Suitable oils include, but are not limited to the following classes: mineral or petroleum oils, such as mineral oil and petrolatum, animal oils such as mink oil and lanolin oil; plant oils, such as aloe extract, sunflower seed oil and avocado oil; and silicone oils such as dimethicone and alkyl methyl silicones.

The amount of wax in the composition can be from about 10 to about 40 percent by weight, more specifically from about 10 to about 30 percent by weight, and even more specifically from about 15 to about of 25 percent by weight. Suitable waxes include, but are not limited to the following classes: natural waxes, beeswax and carnauba wax; petroleum waxes, such as ceresin and paraffin wax; silicone waxes, such as alkyl methyl siloxanes; or synthetic waxes such as synthetic beeswax and synthetic waxy wax.

The amount of fatty alcohol in the composition, if present, can be from about 5 to about 40 percent by weight, more specifically from about 10 to about 30 percent by weight, and even more specifically from from about 15 to about 25 percent by weight. Suitable fatty alcohols include alcohols having a carbon chain length of C, * -C 30, including cetyl alcohol, stearyl alcohol, behenyl alcohol, and dodecyl alcohol.

In order to further improve the benefits to consumers, additional ingredients may be used. The classes of the ingredients and their corresponding benefits include, without limitation, C10 or higher fatty alcohols (lubricity, body, opacity); fatty esters (lubricity, modification of sensation); vitamins (topical medicinal benefits); Dimethicone (skin protection); powders (lubricity, oil absorption, skin protection); preservatives and antioxidants (product integrity); ethoxylated fatty alcohols; (wettability, process aids); fragrance (attraction to the consumer); lanolin derivatives (skin moistening), dyes, optical brighteners, sunscreens, alpha hydroxy acids, natural herbal extracts and the like.

The aggregate amount of total tissue of the composition can be from about 40 percent by weight, more specifically from about 5 to about 25 percent by weight, and even more specifically from about 10 percent by weight. about 15 percent by weight, based on the weight of the tissue. The amount added will depend on the desired effect of the composition on the attributes of the product and the specific composition. A preferred method for uniformly applying the heated composition to the tissue tissue surface is rotogravure printing, either direct or indirect (offset), because it is the most accurate printing process and offers maximum control of the distribution of tissue. composition and the transfer rate. However, other printing methods such as flexographic printing can also be used.

The composition coverage is preferably uniform over essentially the entire surface of the tissue, but only partially covers the surfaces of the tissue product. This is achieved by a large number of small spaced and separated deposits which, when viewed by the eye without help, seem to cover the entire surface, but in fact they do not. The coverage of the actual surface area of the deposits can be from about 30 to about 99 percent, more specifically from about 50 to about 80 percent. ("Surface Area" is the area of a simple plant view of the tissue, not taking into consideration the three-dimensional topography of the tissue which would otherwise increase the surface area value for any given tissue sample). By providing a large number of very small deposits, the penetration of the composition can be controlled more easily to remain essentially on or near the surface of the tissue. Gravure printing is ideally suited for such an application by providing, for example, from about 1,000 tanks per linear inch of surface, or from about 100 to about 1,000,000 tanks per square inch. This encompasses several well-known etching techniques, such as mechanical engraving, etching-acid etching, electronic engraving, and ceramic laser engraving. An example suitable electronic engraving is about 250 deposits per linear inch of surface area, or about 62,500 deposits per square inch. By providing such a large number of small deposits, the uniformity of the distribution of the deposit is very high. Uniformity can be quantified by image analysis as will be described hereinafter and preferably can be characterized by a percent coefficient of variation of about 15 or less, more specifically about 10 or less, and even more specifically from about from 5 to around 15. Due to the large number of small deposits applied to the surface of the tissue, the deposits are more easily resolidified on the surface of the tissue where they are more effective to benefit the user. As a consequence, a relatively small amount of the composition can be used to cover a large area.

In some embodiments, the products of this invention can be characterized by their hydrophobicity, which helps to avoid "wet transfer" to the hands of the user during use. This property can be measured objectively by the sinking time, which is described in the United States patent number 4,950,545 entitled "Multifunctional Facial Tissue" and issued on August 21, 1990 to Walter et al., Which is incorporated here for reference. The sinking time can be about 30 seconds or more, more specifically about 40 seconds or more, even more specifically from about 50 to about 150 seconds or more. These sinking times can be dramatically increased by a factor of 3-5 times by heating the treated tissues of this invention to temperatures of from about 100 to about 150 degrees F. Heat-treated tissues can exhibit sinking times. around 150 or greater.

The tissue product of this invention may be of a stratum, of two strata, of three strata or more. In all cases, the composition is applied to the surface or exterior surfaces of the product. The composition may be applied after the strata are put together or before the strata are brought together. The individual layers can be layered or mixed (homogeneous) to be creped or non-creped, continuously dried or wet compressed. Surprisingly it has been found that the mixed base sheets of tissue provide equivalent performance to the base sheets in layers, whereby the layers are unnecessary.

Detailed Description of the Drawings In the descriptions of the following figures, the same reference numbers will be used to display the same items from figure to figure.

Referring to Figure 1, one aspect of the invention will be described in greater detail. A sheet of tissue 1 is shown approaching a Yankee dryer 2 and being dislodged from the dryer with the creping blade 3. The creped and dried tissue sheet 4 is passed to a heated rotogravure printing station comprising a backing roller 6 and an engraving roll 7, at which point the melted composition is applied to a surface of the tissue sheet. The treated tissue sheet is then rolled onto a roll 8 for subsequent conversion operations.During the printing operation, the melted composition to be applied to the tissue sheet is supplied by a heated supply tank 10 and pumped to the heated doctor application head 11 by a suitable dosing pump. It is necessary to keep the temperature constant in the process. Therefore, the melted composition is continuously circulated between the supply tank and the application head while maintaining an adequate amount in the tank. The heated head applicator head supplies the melted composition to the engraved roll, the surface of which contains a plurality of small cells having a transfer volume necessary to achieve the desired effect. By way of example, a suitable engraving roll has a grid of lines of 250 lines per linear inch and a roll surface volume of 5.0 billion cubic microns (BCM) per square inch of roll surface. The typical cell dimensions for this roller are 150 microns in length, 1 microns in width, and 30 microns in depth.

In operation, the engraved roll is loaded onto the backing roll to force the tissue of the tissue or the sheet to contact the engraved roll. The backing roll can be any material that fills the process requirements such as natural rubber, synthetic rubber or other compressible forces. The loading pressures may vary from about 5-50 pli (roller to roller interference) to a back roll / engrave roller gap of 0.008 inches (without roll to roll contact).

Figure 2 is a view similar to that of Figure 1 differing only in that the tissue sheet to be printed with the melted composition is supplied from a parent roller 15. This is intended to exhibit printing off-line at the which the printing operation is carried out independently of the tissue sheet manufacturing process. The sheet 17 that is printed with the melted composition may be of a single stratum or may be of multiple strata. The resulting sheet is then wound onto a roll 16 for further conversion operations.

Figure 3 is similar to that of Figure 2, but illustrates the direct heated rotogravure printing of two sides of the sheet using two printing stations in sequence. Two-sided printing is desirable when the effect of adding the composition is desired on both sides of a single-layer product or when the tissue product consists of two or more layers.

Figure 4 depicts a two-sided printing of the tissue sheet using a method of printing offset rotogravure on one side of the sheet and a photogravure printing method heated directly on the other side of the sheet. In this method, the engraved roll 7 and the backing roll 6 (now doubling as an offset applicator roll) can be the same as the rolls used for the previously described methods. However, the second engraved roll 20 requires different liquid delivery characteristics and is therefore recorded slightly differently. For such rollers, for example, direct engraving specifications can be from a grid of 250 lines, 5.0 BCM. Typical cell dimensions for such a roller may be 150 microns in length, 110 microns in width, and 30 microns in depth. The offset engraving specifications can be grid of 250 lines, 4.0 BCM, 140 microns in length, 1 microns in width, and 26 microns in depth.

Figure 5 depicts a method for printing both sides of the sheet using a simultaneous heated offset gravure printing.

Figure 6 depicts a method for printing both sides of the sheet in succession using two heated center gravure printing stations. The addition of a backup roller 21 is necessary for each printing station.

Figures 7A and 7B are plan views of the surface of a three layer facial tissue of this invention (7A) and of a PUFFS® Plus facial tissue (7B), which is a tissue treated with commonly available lotion. The two tissues were treated with osmium tetroxide vapors (Os? 4) to make the white / translucent lotion visible against the white pulp fibers in the tissue. Osmium tetroxide reacts with the available carbon double bonds to form osmium metal complexes with carbon. This stabilizes or "sets" the affected material and stains the black material, which is desirable to generate a contrast.

The treatment of osmium tetroxide is carried out by placing the tissue loosely in a glass bell jar having an opening diameter of about 12-16 inches and a depth of about 12 inches. Care should be taken not to stack the tissues, which may impair the proper penetration of the vapors to all the tissues. The osmium tetroxide is received as a crystalline solid in a sealed glass ampule which is broken and opened and placed in the bell jar with the tissues. In the upper part it is placed on the bell jar forming an air proof seal. The tissues remain in the bell jar for about 24 to 48 hours. The osmium teroxide has a high vapor pressure and easily sublimates a gas which permeates the bell jar chamber. After the staining is complete, the bell jar opens and the samples are allowed to air 12 to 24 hours before handling in order to release any residual unreacted vapors. Note: the greatest care should be exercised when osmium tetroxide is used. This is a powerful and highly toxic oxidizer. All procedures with this material must be conducted in a flue hood with adequate air flow.

After treatment with osmium tetroxide, the tissues were viewed under a microscope at a magnification of 7.5X with a cross-polarized light, as shown, the tissue of this invention exhibited greater uniformity in coverage. Uniformity was also confirmed using a gray-level histogram analysis on the inked tissues. The tissue of this invention had an average percent coefficient of variation (VOC) of 10.6, while the PUFFS® Plus tissue had an average percent variation coefficient of 22.6, indicating significantly less variability in the coverage for the tissue. this invention.

In order to measure the percent coefficient of variation, the osmium-treated sheet was seen with a dark or nidirectional field illumination produced with an eight-bulb octagonal ring illuminator surrounding a 50-millimeter Er-Nikkor lens attached to a tube of extension of mount-C of 10 millimeters. This was put into a Quantimet 970 image analysis system (from Leica, Deerfield, Illinois) using a calnicon examiner. The field size (standard live frame) was 2.77 centimeters X 2.17 centimeters. Several fields of the osmium-treated tissue were placed under the lenses and measured using a black photopanel background. A total of six (6) fields were measured. The white analyzer level was always set at 1.00 volts. At the end, the histogram was printed and its standard deviation was divided by its main gray level to produce the coefficient of variation. When X 100 multiplied, this became the percent coefficient of variation.

Referring to Figures 8 and 9 (this invention) and Figure 10 (PUFFS® Plus), three tissues stained with osmium tetroxide were cross-sectioned in the machine direction. Six representative segments (AF) of each tissue were photographed under an increase of approximately 200X to illustrate the difference in the degree of penetration of the composition reservoirs and the ability of the method of this invention to essentially confine the treatment composition to the surface of the treated tissue sheet. As shown, the PUFFS® Plus cross sections illustrate that the treatment was sporadic and non-uniform and more frequently completely penetrated through the tissue. By comparison, the tissues of this invention retained more of the treatment composition on the upper surface of the treated stratum.

The ability of the method of this invention to essentially retain the composition on the surface of the tissue was quantified using an image analysis. More specifically, the optical and image conditions for this analysis were the same as described above for the measurement of uniformity. But in this case, the top surface and bottom surface pieces of each tissue layer were tightly placed next to each other to form a "glue joint" without any separation between the two pieces. The sample was placed under the lenses with for example, the lightest background surface piece on the right of the picture frame and the darkest top surface piece on the left of the picture frame.

If the gray level histogram of the lighter background surface is first measured, the live frame variable is placed over just that region of the image box, with the white level of the examiner set to 1.00 volts for the entire field. Then the sample is rotated so that the lighter background surface is now on the left. The analyzer was adjusted again to 1.00 volts and this surface is again isolated by the variable live frame. This data accumulates in the same gray level histogram. The main gray level for the bottom surface, GLFONDO 'is redressed.

The same procedure was carried out on the darker upper surface occupied by the other half of the image, again, the white analyzer level is set to 1.00 volts for the whole image. (This will tend to compensate for the overall differences in the amount of the composition added to the tissue, while adjusting to zero more adequately on whether the composition is on the top or bottom surface, which reflects the degree of penetration). Again, the main gray level for the upper surface, GLSÜPERIOR 'sß records.

Finally, the difference between the two main gray levels, GLDIFF, is calculated as a value inversely related to penetration: GLDIFF = G FUND "GLSUPERIOR Note that if GLDIFF is zero or negative, then full penetration has occurred. If GLDIFF is strongly positive, then most of the osmium stained composition is seated on the upper surface of the tissue.

The GLDIFF values for the two tissue samples of this invention as illustrated in Figures 8 and 9 were 10.4 and 6.1. For comparison, the PUFFS Plus tissue sample had a GLDIpF value of minus 2.1. In general, the tissues of this invention may be characterized by a GLDIFF of about 5 or greater, more specifically about 10 or greater, and even more specifically from about 5 to about 15.

E J E M P L O S Example 1 A skin moisturizing formula having a melting point of about 45 degrees centigrade having the following composition was prepared: PERCENT BY WEIGHT 1. Dimethicone 100 cst 1 . 0 2. Isopropyl Palmitate 3. . 0 3. Vitamin E acetate 0. . 1 4. Aloe extract 0.. 1 5. Mineral Oil 59. . 8 6. Ceresin wax (M.P. 66-71 ° C) 18. . 0 7. Cetearyl Alcohol 18. . 0 The formula was prepared by premixing dimethicone and isopropyl palmitate until they were uniform. While it was heated, the aloe vera extract and the vitamin E extract were added and mixed. The mineral oil was added and the formula was mixed until it was uniform. The mixing was further heated to a temperature of 55-60 degrees centigrade. Ceresin wax was added. The mixture was further heated to 60-65 degrees centigrade with agitation until the ceresin wax melted. Cetearyl alcohol was slowly added to the mixture while agitation was maintained to prevent lumping. The temperature was maintained at about 55-60 degrees Celsius and continuous mixing until the cetearyl alcohol was melted. At this point, the formula was ready to be used.

The resulting formula was applied to both surfaces of the three-layer wet compressed tissue sheet (basis weight of about 23 pounds by 2,880 square feet) through a heated rotogravure printing process at an aggregate level of 16 percent. by total weight of aggregate as described in Figure 4. Specifically, the formula was premixed around 56 degrees centigrade in a heated stainless steel supply tank. The compression supply system and the press (supply hoses, doctor application heads, and gravure rolls) were preheated to around 55 degrees centigrade. The formula was transferred from the heated application heads to the offset and direct gravure rolls heated.

The gravure rolls were electronically recorded, chromed on copper rolls supplied by Southern Graphics Systems, of Louisville, Kentuky. The direct gravure roll has a grid of lines of 200 cells per linear inch and a volume of 6.08 BCM per square inch of the roll surface. The typical cell dimensions for this roller were 180 microns long, 145 microns wide, and 34 microns deep. The offset engraving roller was a grid of 250 lines, 5.0 BCM, 150 microns in length, 1 microns wide and 3 microns deep. The rubber backing roll / offset applicator roller was a Flex Touch 1 72 ßhore A durometer supplied by Republic Roller, of Three Rivers, Michigan.

The direct gravure roller was set to a condition having about 0.03 inches of separation from the rubber backing roller. The offset gravure roller was set to a condition having 0.375 inches of interference between the gravure roller and the rubber backing roller. The combination of heated and heated direct offset offset printing machine was run at a speed of 750 feet per minute. The composition deposits solidified essentially instantaneously after leaving the press.

When cut into individual facial tissue sheets, the resulting tissue product was prepared by consumers for softness, thickness, absorbency and generally on the PUFFS Plus facial tissue.

Example A skin protection formula having the following composition and a melting point of about 56-60 degrees centigrade was prepared similar to that of Example 1: Percent BY WEIGHT 1. Mineral Oil 59. , 0 2. Zinc Oxide 1. 0 3. Ceresin Wax (M.P. 64-67 ° C.) 20. . 0 4. Cetearyl Alcohol 20. , 0 The above-indicated formula was applied as described above to both surfaces of a non-creped continuous dried bath tissue of a stratum in an amount of 15 percent by weight. The resulting tissue had an improved soft feel and was generally preferred over the Charmin® Plus bathroom tissue.

Example A skin protection / moisturizing formula with a melting point of about 61 degrees centigrade was prepared, having the following composition which was prepared similarly to that of Example 1: Percent BY WEIGHT 1. Dimethicone 2. 0 2. Isopropyl Palmitate 4 .0 3. Acetulan * 5.0 4. Mineral Oil 45.0 5. Vitamin E acetate 2 .0 6. Aloe extract 2.0 7. Ceresin wax (M.P. 66-71 ° C) 20.0 8. Behenyl Alcohol 20.0 * Cetyl acetate and acetylated lanolin alcohol, from Amerchol Corporation.

The formula given above was applied as in Example 1 on both sides of a two-layer facial tissue at a level of 26 percent by weight of total aggregate.

Example 4 A three-layer facial tissue was prepared as described in Example 3, except that the formula aggregate was 18 percent by weight based on the weight of the two outer layers.

Example 5 A facial tissue was prepared as described in Example 4 except that the aggregate level was 22 percent by weight based on the weight of the two outer layers.

In a consumer use test, the tissues of Examples 3, 4 and 5 were all preferred for softness, thickness, absorbency and in general on the PUFFS® Plus.

Example 6 For comparison, treated tissues were prepared as described above with formulas which did not deliver the preferred product to the consumer. Specifically, a first formula was prepared with the following ingredients: PERCENT BY WEIGHT 1. Dimethicone and Dimethicone 5.0 2. Dimethicone 20 cst 15.0 3. Isopropyl Palmitate 3.0 4. Isodecyl Neopentate 20.0 5. Acethulan 7.0 6. Mineral Oil 25.0 7. Griceril Monohydroxystearate 15.0 8. Cetyl Alcohol 10.0 This formula was applied to a two-layer facial tissue as described above with a total aggregate level of 14 percent by weight.

A second formula was prepared with the following ingredients: PERCENT BY WEIGHT 1. Dimethicone 100 cst 2.0 2. Isopropyl Palmitate 4.0 3. Asetulate 5.0 4. Mineral Oil 34.0 5. Cetearet-20 35.0 6. Cetyl Alcohol 20.0 The second formula was applied to a tissue of two strata at a total aggregate level of about 31 percent by weight.

Both products were subjected to a consumer use test for a comparison of preference in relation to PUFFS ™ Plus (control) as was done with the products of Examples 3, 4 and 5. In both cases, PUFFS Plus was preferred . Both test formulas lacked a wax component (as selected from the list described above). It is believed that the lack of a wax component reduced the ability of the oil component to remain on or near the tissue surface and thus the preferred result was avoided.

It will be appreciated that the foregoing Examples, given for purposes of illustration, are not to be construed as limiting the scope of this invention, which is defined by the following clauses and all equivalents thereof.

30. The method as claimed in clause 29 characterized in that from about 30 to about 99 percent of the surface area of the tissue is covered with the composition.

31. The method as claimed in clause 29 characterized in that from about 50 to about 80 percent of the surface area of the tissue is covered with the composition.

32. The method as claimed in clause 28 characterized in that the amount of the composition applied to the tissue is from about 1 to about 40 percent by weight.

33. The method as claimed in clause 28 characterized in that the amount of the composition applied to the tissue is from about 5 to about 25 percent by weight.

34. The method as claimed in clause 28 characterized in that the amount of the composition applied to the tissue is from about 10 to about 15 percent by weight.

35. The method as claimed in clause 28 characterized in that the tissue tissue is cooled before or after the deposits of the coating composition are applied in order to accelerate the solidification of the deposits.

36. The method as claimed in clause 28 characterized in that the composition is heated to a temperature of about 10 degrees centigrade or less above the melting point of the composition.

37. The method as claimed in clause 28 characterized in that the composition is heated to a temperature of about 5 degrees centigrade or less above the melting point of the composition.

38. The method as claimed in clause 28 characterized in that the composition is heated to a temperature of about 2 degrees centigrade above the melting point of the composition.

39. The method as claimed in clause 28 characterized in that the composition contains from about 5 to about 40 weight percent of fatty alcohol. IS IN A soft tissue product is described which has uniformly distributed surface deposits of a solidified composition having a melting point of from about 30 degrees centigrade to about 70 degrees centigrade. The solidified composition is applied to the outer surfaces of the tissue product in melted form, preferably by rotogravure printing. The solidified composition contains an oil, a wax and preferably a fatty alcohol.
