Description

TISSUE PRODUCTS COMPRISING A CLEANSING COMPOSITION BACKGROUND OF INVENTION present invention is directed to cleaning compositions which can be used in combination with tissue products such as facial tissue and for bathroom. More particularly, present invention is directed to novel cleansing compositions for use on one or both surfaces of a tissue product, which improves level of cleanliness and comfort for user as os provide a health benefit to skin. skin is largest organ of human body. As a limit layer, skin performs several main functions: this keeps body at correct temperature, maintains essential fluids, and protects against toxic agents microorganisms and potentially damaging rays of sun. Maintaining right skin is essential for good health. For most people, proper skin maintenance begins with daily cleansing.

Human skin is exposed to 10 polluted by several pollutants daily through contacts with various biological fluids such as urine and faeces, as well as contact with various environmental factors.

Examples of contaminants with which skin is contacted daily include both large positive and high negative bacteria, fungi, mold, protozoa and viruses. Even though most microbes are negatively charged due to r chemical structure, can adhere to skin, which is also typically negatively charged, through electrostatic interactions, hydrophobic interactions and ligand interactions. Even though e fastening mechanisms are not completely understood, r cumulative effect may be to tightly bind numerous microbes such as Candida albicans to skin resulting in inflammation, irritation and / or infection. In addition, numerous o microbes, microbial metabolic products, inorganic waste also make contacts and hurt skin on a daily basis. contaminants listed above as well as numerous os are frequently irritating to skin and can initiate an elaborate cascade of immunological events upon contact with skin cells. Finally, e events can lead to irritation, inflammation and a severe skin infection. Cleaning skin on a daily basis can prevent or minimize skin irritation and inflammation caused by immunological effects.

However, proper cleaning of skin can be difficult due to topography of skin, presence of hair follicles and sensitivity of skin. Small amounts of dirt can accumulate on skin during daily activities. This dirt may contain bacteria and active enzymes that irritate skin and cause personal discomfort. Maintaining skin health by removing or repelling microbes in dirt is an important part of personal hygiene, especially in sensitive areas such as perianal, urogenital and vaginal regions.

DETAILED DESCRIPTION OF THE PREFERRED INCORPORATIONS According to the present invention, it has been found that when at least one surface of a tissue product is treated with a cleaning composition including a thermoplastic polymer or a thermosetting polymer or a water soluble neutral oligosaccharide the skin can be effectively cleaned of dirt and contaminants without substantial damage. Surprisingly, the cleaning composition has a low coefficient of friction upon contact with the skin so that abrasion of the skin is minimal, but it is capable of essentially cleansing the skin.

The present invention is generally described herein in relation to a tissue product. The cleaning compositions described herein are suitable for use on one or both surfaces of a tissue product. Suitable tissue products include, for example, bath tissue, facial tissue, disposable towels, napkins, handkerchiefs and polyolefin cleaning wipes.

The tissue products of the present invention comprise a tissue substrate in combination with a cleaning composition. As used herein, tissue products are intended to include bath tissue, facial tissue, towels, handkerchiefs, napkins, polyolefin wipes and the like. The present invention is useful with tissue and tissue paper products in general, including but not limited to conventionally compressed tissue paper, densified tissue paper with high volume pattern; and high-volume non-compacted tissue paper. The tissue paper suitable for use with the cleaning compositions described herein may be of a homogenous or multi-layered construction, and the tissue products made therefrom may be of a single-strand or multi-strand construction. The tissue paper desirably has a basis weight of between about 10 grams per square meter and about 65 grams per square meter, and a density of about 0.6 grams per cubic centimeter or less. More desirably, the basis weight will be about 40 grams per square meter or less and the density will be about 0.3 grams per cubic centimeter or less. More desirably, the density will be between about 0.04 grams per cubic centimeter to about 0.2 grams per cubic centimeter. Unless otherwise specified, all amounts and weights relative to the paper are on a dry basis. Resistances and tension in the machine direction can be in the range of from about 100 to about 5000 grams per inch in width. The tensile strengths in the cross machine direction are in the range of from about 50 grams to about 2500 grams per inch in width. Absorbency is typically from about 5 grams of water per gram of fiber to about 9 grams of water per gram of fiber.

Conventionally pressed tissue paper and methods for making such paper are well known in the art. Such paper is typically made by depositing a supply for making paper on a luminous forming wire, often mentioned as in the art, as a Fourdrinier wire. Once the supply is deposited on the forming wire this is referred to as a fabric. The fabric is drained by pressing the fabric and drying at elevated temperatures. The particular techniques and typical equipment for making the tissues according to the just described process are well known to those skilled in the art. In a typical process, supply of low consistency pulp was provided from a pressurized headbox, which has an opening for delivering a thin pulp supply reservoir over the Fourdrinier wire to form a wet tissue. The fabric is then typically dewatered to a fiber consistency of between about 7% and about 25% (total fabric weight basis) by vacuum draining and further drying by pressing operations wherein the fabric subjected to the pressure developed by the opposing mechanical members as for example, the cylindrical rollers. The dewatered fabric is then further pressed and dried by a steam drum apparatus known in the art as a Yankee dryer. The pressure can be developed in the Yankee dryer by mechanical means such as an opposing cylindrical drum that presses against the tissue. The multiple Yankee dryer drums can be used so that additional pressing is optionally incurred between the drums. The sheets formed are considered to be more compact since the entire fabric is subjected to substantial mechanical compression forces while the fibers are wet are then dried while in a compressed state.

Densified tissue paper with a high volume pattern is characterized by having a relatively high volume field of relatively low fiber density and an array of densified areas of relatively high fiber density. The high volume field is alternatively characterized as a field of pillow regions. The densified zones are alternatively referred to as knuckle regions. The densified zones can be discretely spaced within the high volume field or can be interconnected, either completely or partially with the high volume field. The patterns can be formed in a non-ornamental configuration or they can be formed to present ornamental designs on the tissue paper. Preferred processes for making the tissue tissues identified are described in U.S. Patent Nos. 3,301,746 (Sanford et al.), Issued January 31, 1967; 3,974,025 (Ayers) granted on August 10, 1976; and 4,191,609 (Tro han), granted on March 4, 1980; and 4,637,859 (Trokhan) granted on January 20, 1987; all of which are incorporated here by reference.

In general, patterned densified fabrics are preferably prepared by depositing a paper supply on a perforated forming wire such as a Fourdrinier wire to form a wet fabric and then juxtaposing the fabric against a support arrangement. The fabric is pressed against the arrangement of supports, thus highlighting areas densified in the tissue in places geographically corresponding to the points of contact between the support arrangement and the wet tissue. The rest of the uncompressed tissue during this operation is mentioned as a high volume field. This high volume field may also be densified by the application of fluid pressure, such as a vacuum type device or with a continuous blow dryer or by mechanically pressing the fabric against the support arrangement. The fabric is dewatered, and optionally pre-dried, in such a manner as to essentially prevent compression of the high volume field. This is preferably achieved by fluid pressure, such as with a vacuum-type device or a continuous blow dryer, or alternatively by mechanical pressing of the fabric against an array of supports where the high volume field is not compressed. The operations of drainage, optional pre-drying and formation of the densified zones can be integrated or partially integrated to reduce the total number of processing steps carried out. Subsequent the formation of the densified forms the drainage and the optional pre-drying, the fabric dried until complete, preferably still avoiding mechanical pressing. Preferably from about eight percent to about 55 percent of the tissue paper surface comprises densified rollers having a relative density of at least 125% of the density of the high volume field.

Desirably, the supply is first formed in a wet fabric over a perforated forming carrier, such as a Fourdrinier wire. The fabric is drained and transferred to a printing fabric. The supply may alternatively be initially deposited on a perforated carrier carrier which also operates as a printing fabric. Once formed, the wet fabric is dewatered and, preferably, thermally pre-dried to a fiber consistency selected from about 40% to about 80%. The drain is preferably carried out with suction boxes or other vacuum devices or with continuous blow dryers. The knuckle print of the printing fabric is printed on the fabric as discussed above, before drying the fabric to complete. One method to achieve this is through the application of mechanical pressure. This can be done, for example, by pressing a _ ^ 13 holding point roller holding the printing fabric against the face of a drying drum, such as a Yankee dryer, where the fabric is placed between the pressure point roller and the drying drum. Also, preferably, the fabric is molded into counting of the printing fabric before complete drying by applying the fluid pressure with a vacuum device such as a suction box, or with a continuous blow dryer. The fluid pressure can be applied to induce printing of the densified zones during the initial drain, in a subsequent and separate process step or a combination thereof.

The densified tissue paper structures without and not compacted are described in the Patents of the United States of America Numbers 3,812,000 of (Salvucci et al.) Granted May 21, 1974 and Patent Number 4,208,459 (Becker et al.), Granted on June 17, 1980 both of which are incorporated by reference. In general Uncompacted patterned densified tissue paper structures are prepared by depositing a paper supply on a perforated forming wire such as a Fourdrinier wire to form a wet tissue, draining the tissue and removing the additional water without mechanical compression. until the fabric has a fiber consistency of at least about 80% and creping the fabric. The water is removed from the fabric as drainage with vacuum and thermal drying. The resulting structure is a high volume but weak sheet of relatively uncompacted fibers. The binding material is preferably applied to parts of the fabric before creping.

Compact densified patterned tissue structures are commonly known in the art as conventional tissue structures. In general, compacted unconfined tissue paper structures are prepared by depositing a paper supply on a forming wire such as a Fourdrinier forming wire to form a wet tissue, draining the tissue and removing the additional water with the aid of a uniform mechanical compaction (pressing) until the fabric has a consistency of 25-50%, transferring the fabric to a thermal dryer such as a Yankee that repairs the fabric. In general, the water is removed from the fabric by vacuum, mechanical pressing and thermal means. The resulting structure is strong and generally of a singular density, but very low in volume, absorbency and softness.

The papermaking fibers used in repairing the tissue paper for the products of the present invention will normally include fibers derived from wood pulp. Other fibrous cellulosic pulp fibers, such as cotton yarns, bagasse, etc., may be used and are intended to be within the scope of this invention. Synthetic fibers, such as rayon, polyethylene and polypropylene fibers can also be used in combination with natural cellulosic fibers. An example of polyethylene fiber that can be used is PULPEX.RTM, available from Hercules, Inc. (Wilmington, Delaware).

Applicable wood pulps include chemical pulps such as Kraft, sulphite and sulfate pulps, as well as mechanical pulps including, for example, ground wood, thermomechanical pulp and chemically modified thermomechanical pulp. Chemical pulps, however, are typically desirable since they impart a superior feeling of softness to the tissue sheets made therefrom. The pulps derived from both the deciduous trees and the coniferous trees can be used. Also useful in the present invention are fibers derived from recycled paper, which may contain any or all of the above categories as well as other non-fibrous materials such as fillers and adhesives used to facilitate the manufacture of original paper.

In addition to the papermaking fibers, the supply for making paper used to make the tissue paper structures may have other components or materials added thereto as may be or subsequently known in the art. Desirable additive types will depend on the particular end use contemplated for the tissue sheet, e.g. products, such as bathroom tissue, paper towels, facial tissues and other similar products, to wet strength High is a desirable attribute. Therefore, it is often desirable to add chemical substances known in the art to the papermaking supply as "wet strength" additives.

In addition to the wet strength additives, it may be desirable to include certain lint control additives and dry strength additives known in the art in the papermaking fibers. In this regard, the starch binders have been found to be particularly suitable. In addition to reducing the dyeing of the finished tissue paper product, low levels of starch binders also impart a modest improvement in dry-care strength without imparting stiffness that could result from the addition of high levels of starch. Typically, the starch binder is influenced 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 dried tissue paper.

The cleaning formulas described herein for use in combination with the tissue product are either solid or semi-solid at room temperature. As used herein, the term "semi-solid" means that the cleaning formulation has a typical rheology of plastic or pseudoplastic fluids. When applied to the tissue product, the cleaning formulations described herein impart a smooth, lubricated feel and a lotion-like feel. Cleansing formulations gently remove microbes and dirt with use to improve the health of the user's skin.

The tissue product includes a cleaning composition as described herein on at least one surface thereof. The cleaning composition provides a cleansing function on the surface of the skin, while being gentle and non-abrasive to the skin essentially. As used herein, the term "gentile" means that the soft composition does not cause substantial damage to the stratum corneum layer of the skin with use, and is minimally abrasive to the surface of the skin. As noted above, in one embodiment, the cleaning compositions of the present invention for use in combination with a tissue product comprise a thermoplastic polymer. As used herein, the term "thermoplastic polymer" refers to a material that softens when exposed to heat and which essentially returns to a non-softened condition when cooled to room temperature. These compounds can be melted again and cooled several times without undergoing any change or appreciable chemical deterioration.

Suitable thermoplastic polymers for use in these cleaning compositions described herein include both thermoplastic powders and thermoplastic resins which are insoluble in oils. These thermoplastic powders and the thermoplastic resins are suitably insoluble in the oily soils and in the aqueous soils typically present on the surfaces of the skin. As such, they tend to impart a silky, smooth and smooth feel to the user's skin. With use the thermoplastic polymer can provide a ball bearing type effect on the surface of the skin, which also imparts an elegant feel and improved slip without substantially damaging the surface of the skin.

The cleaning compositions of the present invention comprise from about 10% by weight of the cleaning composition to about 90% (by total weight of the cleaning composition) of the thermoplastic polymer. As used herein the term "by total weight of the cleaning composition" refers to the total weight of the cleaning composition including all components thereof for example, if the cleaning composition comprises 25% (by total weight of the cleaning composition) of thermoplastic polymer and has a total weight including all components of 100 grams, the composition comprises 25 grams of thermoplastic polymer.

The thermoplastic polymers included in the cleaning composition may suitably be in the form of a spherical resin or spherical powder. To provide the intended benefits of the present invention, the thermoplastic polymers suitably have an average particle diameter of from about 0.1 micrometers to about 20 micrometers, and suitably from about 0.1 micrometers to about 12 micrometers, and even more adequately from about 0.04 micrometers to about 7 micrometers. Within these ranges, the thermoplastic polymers can both provide a cleaning and softness function.

Specifically, thermoplastic polymers suitable for use in cleaning compositions include but are not limited to polymethyl methacrylate, available as MP-2200, ES-830, and BPA-500 manufactured by KOBO Products, Inc. (South Plainfield, NJ), polymer methacrylate crosslinker manufactured by KOBO (South Plainfield, NJ). Polyethylene available as CL-2080 manufactured by KOBO (South Plainfield, NJ), ethylene / acrylate copolymer, available as EA-209 manufactured by KOBO (South Plainfield, NJ), Nylon_12, available as SP-500 and SP-501 manufactured by KOBO (South Plainfield, NJ), polymethylsiloquois manufactured by KOBO (South Plainfield, NJ), ethylene vinyl alcohol, polyvinyl acetate, acrylic, polyvinyl acetate acrylate, acrylates, polyvinyl bichlorides, ethylene vinyl acetate, vinyl chloride ethylene, polyvinyl chloride, styrene, styrene acrylate, styrene / butadiene, styrene / acrylonitrile, butadiene / acrylonitrile, acrylonitrile / butadiene / styrene, acrylic acid ethylene, polyethylene, urethanes, polycarbonate, polypropylene, polyesters, polyimides and silicone resins.

Particularly preferred thermoplastic polymers include polymethyl methacrylates and cross-linked polymers of methyl methacrylate.

Suitable silicone resins are characterized by their three-dimensional structure having a linked siloxane column. Suitable silicone resins include TP-120A, TP-145A, and TP-2000B, manufactured by KOBO, as well as KMP-590 and KMP-599 manufactured by Shin-Etsu Co. , Ltd. (Tokyo, Japan). Silicone resins suitable for use in the cleaning compositions are a mixture of toluene or xylene solvents with combined hydrolysates of methyl chlorosilanes and phenyl chlorosilanes containing hydroxyl groups.

In an embodiment of the present invention, the cleaning composition includes, as the thermoplastic polymer component, a spherically shaped polymethyl methacrylate powder. Suitably, the spherically shaped polymethyl methacrylate powder has an average particle diameter of from about 0.1 micrometers to about 20 micrometers, more suitably, from about 0.01 micrometers to about 12 micrometers, and even more adequately, from about 0.4 micrometers to around 7 micrometers.

As noted above, the cleaning compositions additionally include a neutral oligosaccharide soluble in water. The water-soluble neutral oligosaccharide component of the cleaning composition is generally present in the amount of from about 10% (by total weight of the cleaning composition) to about 90% (by total weight of the cleaning composition). Neutral water-soluble oligosaccharides suitable for the raid of the cleaning compositions of the present invention include, but are not limited to, starches, dextrins, inulins and xanthans.

Suitable starches include those derived from sources including corn starch, potato starch, arrowroot, rice starch, sip gum, and tapioca starch. Suitably, the starch for inclusion in the cleaning composition may be a high molecular weight water soluble starch. As used herein, the term "high molecular weight" refers to a molecular weight of at least about 0.5 kilodaltons, and suitably from about 0.5 kilodaltons to about 1000 kilodaltons or more.

In a suitable embodiment, the water soluble starch of a water soluble dextrin of high molecular weight even more suitably, the water soluble molecular weight starch is amylodextrin. Amilodextrin is a water soluble dextrin of high molecular weight (about 25 kilodaltons) specific produced by the hydrolysis of partial starch acid.

In one embodiment of the present invention, the cleaning compositions described herein comprise the thermoplastic polymer and the water soluble neutral oligosaccharide in a weight ratio of from about 1: 9 to about 9: 1 respectively. In a desired embodiment, the proportion by weight is from about 6: 1 to about 9: 1 of thermoplastic polymer to neutral oligosaccharide soluble in water.

Without wishing to be bound by a particular theory, it appears that the cleansing compositions of the present invention provide improved cleansing of the skin by affecting the static coefficients of friction, or the frictional force required to break the injury of contaminants such as microbes. in dirt, from the surface of the skin. A high static coefficient of friction imparts an abrasive feeling to the skin; while a lower static coefficient of friction imparts softness. The cleaning compositions provide a static coefficient of friction which, while permitting sufficient cleaning, is suitably non-abrasive to the surface of the skin.

Additionally it appears that thermoplastic polymers, such as polymethyl methacrylate, impart a somewhat higher coefficient of friction, providing a somewhat abrasive effect to the user's skin. This allows an improved cleaning of the skin. The water-soluble neutral oligosaccharide, such as water-soluble starch, provides a mitigating effect to the abrasiveness of the thermoplastic polymer, thereby allowing a milder cleaning composition. Thus, the cleaning composition of the present invention has the ability to provide improved skin salinity by improving the level of cleaning while it remains soft on the wearer's skin.

In another embodiment of the present invention, the cleaning composition comprises a settled polymer and a neutral oligosaccharide soluble in water. As used herein the term "thermoset polymer" refers to a material that becomes permanently hard and rigid when heated or cured. Therefore, once reacted, the thermoset polymers can not be melted again or molded again without essentially destroying their original molecular characteristics. The thermoset polymers suitable for use in the cleaning composition include both the thermosetting powders and the thermosetting resins.

The cleaning compositions of the present invention may comprise from about 1% (by total weight of the cleaning composition) to about 40% (by total weight of the cleaning composition) of the first thermosetting.

The thermoset polymers for use in the cleaning composition include, but are not limited to epoxy, phenolic, bismaleimide, polyimide, melamine / formaldehyde, polyester, urethanes, urea and urea / formaldehyde.

In some cleaning compositions described herein, the thermosetting polymer and the water soluble neutral oligosaccharide are present in a weight ratio of from about 1: 9 to about 9: 1 respectively. In a desired embodiment, the proportion by weight is from about 6: 1 to about 9: 1 of thermosetted polymer to neutral oligosaccharide soluble in water.

The cleaning compositions of the present invention may optionally also include other components such as emulsifiers, surfactants, water, viscosity modifiers, pH modifiers. Shock absorbers, enzyme inhibitors / inactivators, suspension agents, neutral humidifying factors, humectants, moisturizers, microencapsulated skin health benefit agents, emollients, pigments, dyes, dyes, perfumes, antibacterial active, antifungal assets, pharmaceutical actives, film formers, deodorants, pacifiers, astringents, solvents, organic acids, agents dyes, preservatives, antiviral assets, drugs, vitamins, aloe vera, panthenol and the like. These materials are known in art and are used in their established manner in art in established quantities in art.

The cleaning compositions of the present invention are introduced into one or both surfaces of a tissue paper in an amount sufficient to provide a cleaning benefit in a gentle manner. For example, the cleaning compositions of the present invention can be introduced into one or more surfaces of a tissue paper in an amount of from 0.1% (by weight of the tissue paper) to about 25% by weight of the tissue paper) more suitably from about 1% (by weight of the tissue paper) to about 5% of 2% (by weight of the tissue paper).

In another embodiment of the present invention the tissue products described herein comprise a cleaning composition such that these have a specific cleaning value in combination with the specific softness value. The cleaning value and the softness value of a specific tissue product can be determined using the procedures set forth in the examples described herein. Specifically, it is desirable that the tissue product comprising the cleaning compositions described herein have a cleaning value of more than 0.8, suitably greater than about 1.0, in combination with a skin softness value of less than about 1.05 and suitably of less than around 1.0.

As described in the examples, both cleaning values and the softness value are measured and referred to a Standard. The better the tissue product is cleaned, the higher the cleaning value, while the softer the tissue, the lower the softness value. By requiring a tissue product to have both a required cleaning value and a required softness value, the superior tissue products are delivered since the tissue product is a highly effective but gentle skin cleansing agent on the skin. outer layers of the skin so that abrasive damage is not imparted.

The present invention is illustrated by the present invention is illustrated by the following examples are not intended to be limiting in any way.

Example 1 In this example for the bathroom and the pure bath tissue comprises several cleaning compositions (hereinafter referred to as "test tissues") were tested to determine their softness on the human skin simulator. The softness on the skin was determined by the ratio of the static coefficient of friction of the test tissue with the static coefficient of friction to a corduroy control substrate.

Each tested tissue was cut into 6cm x 6cm sections with 8cm laterals parallel to the perforations on the tissue. The tissue was then allowed to equilibrate in a controlled environment at 23 ° C and 50% relative humidity for at least four hours before the use.

The Vitro Skin ™ N19-5X (IMS, Milford, CT) was used as a skin simulator. The Vitro Skin ™ was cut into pieces of 4cm x 13.5cm and left to hydrate for twenty hours in a hydration chamber. The hydration chamber consisted of a large Tupper are container (35cm X 24cm X 12cm) filled with 500ml of 30% glycerol available from Sigma (St. Louis, MO) and water solution. The hydration chamber can be placed in a controlled environment with a temperature of 23 ° C and 50% relative humidity.

A sliding and friction / monitor instrument, available as model 32-06 from TMI (Amityville, NY) was used to perform the friction force measurements. The sliding and friction instrument was calibrated before each use as specified by the manufacturer. A modified sled was made to measure to have a bottom surface area of 5cm by 3cm and a weight of 73 grams. The sliding and friction instrument was set to move the sled to a 38.1 cm cup. per minute and to stop after having moved 8.25cm. A weight of 1000 grams was placed on the sled before beginning the test to add an extra weight. The normal force was set at 1074 grams to account for the sled, the weight of 1000 grams, the test tissue samples and the fasteners. The forward speed of the sled was set at 15 inches per minute.

All the tests were carried out in a controlled environment having a temperature of 23 ° C and 50% relative humidity. All the dry cleaning compositions to be tested were applied to the bath tissue by placing 20 grams of the cleaning compositions in a plastic zip lock. Six cut sheets of Cottonelle bath tissue were placed inside the bag. The bag was then vigorously shaken. The materials together with the compositions used are listed in Table 1.

Table 1 * Cottonelle is commercially available as a bathroom tissue from Kimberly-Clark orld ide, Inc.

** Cottonelle A & E is a commercially available bath tissue from Kimberly-Clark orldwide, Inc.

After the agitation was discontinued, a sheet of recumbent test tissue was removed. The coating varied from about 5 mg to about 10 mg per cut sheet of test tissue. The test tissue was attached to the lip of the sled using three mini-fasteners, available from EXP (Broomfield, CO); a bra on top and a bra on each side. The fasteners' finger grips were bent so that they could not touch the Vítro Skin ™ during the test.

A piece of Vitro Skin ™ was placed on the bright part of a 5cm by 125cm piece of silicone skin available from SiliClone of (Valley Forge, PA) and the instrument was secured with the sample retaining clip of the slider and friction. The edge of the Vitro Skin ™ was secured with the same fastener. The sled with the test tissue attached was placed in its position on the instrument and aligned on the Vitro Skin ™ - A new piece of Vitro Skin ™ and test floor was used for each test, and a cleaning was carried out by test.

In order to ensure the consistency of the day-to-day sliding and friction instrument, a corduroy material available as a 1611 warp cotton cord style manufactured by Test Fabrics (West Pittston, PA) was designated as the control material and was Tested every day on the instrument. The average static coefficient of friction value of the control material was compared with the static coefficient of the friction values of the previous days to ensure that there was no statistical difference.

Each test tissue was tested six times and the static coefficient of friction for each test tissue was averaged. The differences between the test tissues were determined by using the ANOVA analysis of variation on the static coefficient of the friction values.

The softness of the test tissues was determined by dividing the static friction coefficient of the test tissue, or the force required to initiate the movement of the tissue, by the static coefficient of friction of the cord control. A softer cleaning composition will result in a lower softness value. As noted in Table 2, tissues containing 9: 1 soluble starch 2: PMMA resulted in a lower softness value, 0.775, which corresponds to the milder composition.

TABLE 2 Softness value = static coefficient of friction of test material / static coefficient of friction of corduroy control.

Example 2 In this example, a pure bath tissue and a bath tissue comprising various cleaning compositions (hereinafter referred to as "test tissues") were tested to determine their ability to effectively cleanse a human skin simulator. The cleaning effectiveness was determined by comparing the cleaning performance of the test tissue with the cleaning performance of an uncleaned Vitro-Corneum ™ piece, the control.

Each test tissue was cut into pieces of 13cm by 5cm. The test tissue was then left to equilibrate in a controlled environment at 23 ° C and 50% relative humidity for at least 4 hours before use.

The Vitro-Corneum ™ (IMS, Milford, CT) was used as a skin simulator. The Vitro-Corneum ™ was cut into pieces of 5cm by 5cm. 20 Microliters of fluorescent beads modified with 10-meter carboxylates, available from Bangs Laboratories, Inc. (Fishers, IN) were supplied to each piece of Vitro-Corneum ™, the pieces are then allowed to hydrate overnight in a hydration chamber. The hydration chamber consisted of a large Tupper are container (35 cm by 24 cm by 12 cm) filled with 500 ml of 30% glycerol, available from Sigma (St. Louis, MO) and water solution. The hydration chamber was placed in a controlled environment of a temperature of 23 ° C and 50% in a relative manner.

All the tests were carried out in a controlled environment having a temperature of 23 ° C and a relative humidity of 50%. All the dry cleansing compositions to be tested were applied to the bath tissue by placing 20 grams of the cleaning mixtures in the plastic ziplock bag. Six cut sheets of Cottonelle bath tissue were placed in the bag. The bag was then vigorously agitated. The materials together with the compositions used are listed in Table 3.

Cottonelle NONE N / A Cottonelle 18g PMMA + 2g Sigma (St, Louis, Sigma Starch (S-MO) 4126) or mix bag Cottonelle 20g Sigma sigma starch (St. Louis, soluble (S4126 + 2g MO) PMMA per bag of mix (: 1 soluble starch: P Cottonelle A &E NONE N / A Cottonelle 18g sigma starch Sigma (St , Louis, soluble (S4126 + 2g MO) PMMA per bag of mixture (: 1 soluble starch: P 18g After the agitation was discontinued, a sheet of test coated tissue was removed. The coating varied from about 5 mg to about 10 mg per cut sheet of test sheet tissue.

The test tissue was loaded onto the cleaning efficiency measuring system 1 (CEM L) cleaning instrument, available from Kimberly-Clark (Neenah, WI). The CEM L was developed to evaluate the characteristics of bath tissue cleaning products. The instrument consists of a horizontal mobile bed to contain the test fluids and substrates. A probe capable of containing the test tissues was suspended above the horizontal bed.

A piece of "Vitro-Corneum ™" was secured on the horizontal bed of the CEM I using the tape. The CEM I probe was then lowered to the horizontal bed. The CEM I was moved by a variable speed C motor and the sliding wire assembly to create a cleaning motion. All test tissue samples were tested by cleaning in the transverse direction, with the side of the fabric in contact with the Vitro-Corneum ™. The Cottonelle® roll cleaners were tested with machine direction cleanliness.

The Vitro-Corneum ™ was cleaned once with the material to be examined. If a repetitive cleaning was necessary, each cleaning was carried out with a fresh piece of test tissue. The Vitro-Corneum ™ pieces and / or the test floors were placed in a 50ml conical tube. 20ml of 0.25% sodium sulfate available from Sigma (St. Louis, MO) was added to each tube. The beads were extracted from each sample using a VirSonic® microtip probe sonicator (Gardiner, NY). Three samples of two milliliters were removed from each of the 50 ml conical tubes and placed in 5ml tubes for flow cytometric analysis using the FACSCalibur® flow cytometer. Available from Becton Dickinson Biosciences (San José, CA). Using the CellQuest software available from Becton Dickinson Biosciences, the acquired data were analyzed and the desired population of accounts was counted.

To compare the test materials, a cleaning value was calculated by dividing the number of beads acquired by the control, a piece of Vitro-Corneum ™ not cleaned with the beads applied and extracted using the sonication method described above. A higher cleaning value corresponds to a better cleaning composition. The floors containing 9: 1 PMMA: soluble starch n resulted in the highest cleaning values 1,210, which correspond to the best cleaning composition. These results are shown in table 4.

Table 4 Cleaning value = Number of beads acquired by the test floor / number of beads acquired by the control.

In view of the above, it will be seen that several objects of the invention are achieved. As various changes can be made in the products described above and in the undivided methods of the scope of the invention, it is intended that all the matl contained in the above description be interpreted as illustrative and giving a limiting sense.
