Description: PERSONAL CARE ARTICLES TECHNICAL FIELD The present invention relates to disposable, personal care articles useful for cleansing and/or therapeutically treating the skin, hair and any other sites in need of such treatment These substantially dry, disposable personal care articles comprise a water insoluble substrate comprising a first layer compπsing a nonwoven ply and a polymeric net arranged with said nonwoven ply and either a cleansing component disposed adjacent to the water insoluble substrate, wherein the cleansing component compπses from about 10% to about 1000%, by weight of the water insoluble substrate, of a lathering surfactant or a therapeutic benefit component which comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit agent or both Consumers use the articles by wetting them with water and rubbing them on the area to be cleansed and/or therapeutically treated (e g , conditioned) The invention also encompasses methods for cleansing and/or conditioning the skin and hair using the articles of the present invention BACKGROUND OF THE INVENTION Personal care products, particularly cleansing and conditioning products, have traditionally been marketed in a variety of forms such as bar soaps, creams, lotions, and gels Typically, these products have attempted to satisfy a number of criteria to be acceptable to consumers These criteria include cleansing effectiveness, skin feel, mildness to skin, hair, and ocular mucosae, and lather volume Ideal personal cleansers should gently cleanse the skin or hair, cause little or no irritation, and should not leave the skin or hair with a heavy buildup or overly dry when used frequently It is also highly desirable to deliver such cleansing and conditioning benefits from a disposable product Disposable products are convenient because they obviate the need to carry or store cumbersome bottles, bars, jars, tubes, and other forms of clutter including cleansing products and other products capable of providing therapeutic or aesthetic benefits Disposable products are also a more sanitary alternative to the use of a sponge, washcloth, or other cleansing implement intended for extensive reuse, because such implements can develop bacterial growth, unpleasant odors, and other undesirable characteristics related to repeated use The articles of the present invention surprisingly provide effective cleansing and/or therapeutic benefits to the skin and hair in a convenient, inexpensive, and sanitary manner The present invention provides the convenience of not needing to carry, store, or use a separate implement (such as a washcloth or sponge), a cleanser and/or a therapeutic benefit product These articles are convenient to use because they are in the form of either a single, disposable personal care article or multiple disposable articles useful for cleansing as well as application of a therapeutic or aesthetic benefit agent Moreover, these articles are suitable for use within or m conjunction with another personal care implement that is designed for more extensive use In this instance, the articles of the present invention are disposed within or attached to a separate personal care implement that is not readily disposable, e g , a bath towel or washcloth In addition, the disposable articles of the present invention may be removeably attached to a handle or grip suitable for moving the article over the surface to be cleansed and or therapeutically treated (e g , conditioned) Although in preferred embodiments the articles of the present invention are suitable for personal care applications, they may also be useful in a variety of other industries such as the automotive care, marine vehicle care, household care, animal care, etc where surfaces or areas are in need of cleansing and/or application of a benefit agent, e g , wax, conditioner, UV protectant, etc In preferred embodiments of the present invention, the articles are suitable for personal care applications and are useful for cleansing and or therapeutically treating the skin, hair, and similar keratinous surfaces in need of such treatment Consumers use these articles by wetting them with water and rubbing them on the area to be cleansed The article consists of a water insoluble substrate having a water insoluble substrate comprising a first layer comprising a nonwoven ply, a polymeric net arranged with the nonwoven ply, either a cleansing component containing a lathering surfactant or a therapeutic benefit component or both Without being limited by theory, the substrate enhances lathering which in turn increases cleansing and exfoliation, and optimizes delivery and deposition of a therapeutic or aesthetic benefit agent that might be contained within the article SUMMARY OF THE INVENTION The present invention relates to a substantially dry, disposable personal care article suitable for cleansing, said article comprising a) a water insoluble substrate comprising a first layer comprising 1) a nonwoven ply, 2) a polymeric net arranged with said nonwoven ply, and b) a cleansing

2) a polymeπc net arranged with said nonwoven ply, and a) a therapeutic benefit component, disposed adjacent to said water insoluble substrate, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit The present invention also relates to a method of cleansing and/or conditioning the skin and hair which comprises the steps of a) wetting such articles with water and b) contacting the skin or hair with the wetted articles All percentages and ratios used herein, unless otherwise indicated, are by weight and all measurements made are at 25°C, unless otherwise designated The invention hereof can comprise, consist of, or consist essentially of, the essential as well as optional ingredients and components described therein In the description of the invention various embodiments and/or individual features are disclosed As will be apparent for the skilled practitioner all combinations of such embodiments and features are possible and can result m preferred executions of the invention All documents referred to herein, including patents, patent applications, and printed publications, are hereby incoφorated by reference in their entirety in this disclosure DETAILED DESCRIPTION OF THE INVENTION As used herein, "disposable" is used in its ordinary sense to mean an article that is disposed or discarded after a limited number of usage events, preferably less than 25, more preferably less than about 10, and most preferably less than about 2 entire usage events As used herein, "substantially dry" means that the articles of the present invention exhibit a Moisture Retention of less than about 095 gms, preferably less than about 0 75 gms, even more preferably, less than about 0 5 gms, even more preferably less than about 0 25 gms, even still more preferably less than about 0 15 gms, and most preferably, less than about 0 1 gms The determination of the Moisture Retention is discussed later The personal care articles of the present invention comprise the following essential components WATER INSOLUBLE SUBSTRATE The articles of the present invention comprise a water insoluble substrate which further comprises a first layer which comprises a fibrous nonwoven ply and a polymeric net Preferably, the substrate is soft yet invigorating to the skin of the consumer when used In any case, however, the first layer and any optional additional layers are each defined as having both an interior and exterior surface In any case, the interior surfaces of the layers are those which face the inside or innermost portion of the article of the present invention whereas the exterior surfaces of the layers are those which face the outside or outermost portion of the article Generally, the orientation of the articles of the present invention may be defined such that the first layer is closer to the side of the article to be contacted with the area to be cleansed and/or therapeutically treated, e g the skin/site contact side In any case, however, any layers or sides of the article are suitable for contact with the skin Without being limited by theory, the water insoluble substrate enhances cleansing and/or therapeutic treatment The substrate can have the same or differing textures on each side or surface such that the gripping side of the article is the same or a different texture as the skin/site contact side The substrate may act as an efficient lathering and exfoliating implement By physically coming into contact with the skin or hair, the substrate significantly aids cleansing and removal of dirt, makeup, dead skin, and other debris In preferred embodiments, however, the substrate is non-scouring or nonabrasive to the NONWOVEN PLY AND POLYMERIC NET The first layer of the water insoluble substrate of the present invention further comprises a nonwoven ply and a polymeric net arranged therewith The first layer may also optionally comprise additional nonwoven plies These nonwoven plies are preferably fluid-permeable This nonwoven plies are useful for engaging or retaining the cleansing component and/or therapeutic benefit component within the article Furthermore, the nonwoven plies are also well suited for contact with the skin in which case it is preferred that such plies are soft to the skin The polymeric net is arranged with the nonwoven ply, e g , through lamination via heat or chemical means such as adhesives, through hydroentanglement, etc This arrangement enhances the integrity of the first layer as well as the overall article thereby increasing the substantivity of the article Polymeric nets (referred to herein as a "scrim" materials) which are useful herein are described m detail m U S Patent No 4,636,419, which is incorporated by reference herein The scrim materials can be formed directly at the extrusion die or can be derived from extruded films by fibrillation or by embossing, followed by stretching and splitting The scrim can be derived from a polyolefin such as polyethylene or polypropylene, copolymers thereof, poly(butylene terephthalate), polyethylene terephthalate, Nylon 6, Nylon 66, and the like Furthermore, the scrim materials can be multiconstituent (I e , made up of more than one material), multicomponent (I e , a material which includes at least two filament types) Scrim materials are available from various commercial sources A preferred scrim material useful in the present invention is a polypropylene scrim, available from Conwed Plastics (Minneapolis, MN) Another preferred scrim material is a polyethylene scrim, particularly a low density polyethylene, which is also available from Conwed In another aspect of the present invention, Applicants have also discovered that the incorporation of the scrim material into the first layer, followed by heating, provides macroscopic three-dimensional character to the sheet This macroscopic three-dimensionality has been found to greatly enhance cleansing performance of the article, even where the basis weight of the sheet is essentially uniform In particular, macroscopic three-dimensionality is achieved when the scrim/fiber composite is subjected to heating, then cooling This process results in shrinkage (m the X-Y dimension) of the scrim and, as a result of its being attached with the fibers, provides a sheet with greater three-dimensionality As used herein, the term "X-Y dimension" refers to the plane orthogonal to the thickness of the layer, ply, or article, or a component thereof The X and Y dimensions usually correspond to the length and width, respectively, of the sheet or a sheet component As used herein, the term "Z-dimension" refers to the dimension orthogonal to the length and width of the cleaning sheet of the present invention, or a component thereof The Z-dimension usually corresponds to the thickness of the sheet The degree of added three-dimensionality is controlled by the level of shrinking of (e g , by heating) the scπm/cleaning combination The inclusion of a scrim is particularly beneficial when the fiber aspect of the structure is a nonwoven, particularly when the structure is hydroentangled Further detail of suitable scrim material containing nonwovens may be found in copending U S Application Serial Nos 09/082,396 and 09/082,349, both filed on May 20, 1998, by Fereshtehkho et al., which are incoφorated by reference herein in their entirety Materials suitable for the nonwoven plies are nonwovens selected from the group consisting of sponges (i.e., both natural and synthetic), formed films, fibrous nonwovens, battings, and combinations thereof. Preferably, the nonwoven ply comprises a fibrous nonwoven. As used herein, "a fibrous nonwoven" means that the layer comprises fibers which are not woven into a fabric but rather are formed into a sheet, mat, or pad layer. The fibers can either be random (i.e., randomly aligned) or they can be carded (i.e., combed to be oriented in primarily one direction). In one embodiment, the nonwoven plies are apertured. The apertures in the nonwoven plies of the water insoluble substrate will generally range in average diameter between about 0.5 mm and 5 mm. More preferably, the apertures will range m size between about 0.1 mm to 4 mm m average diameter. Preferably, no more than about 10% of the apertures in the nonwoven first layer of the substrate will fall outside these size ranges. More preferably, no more than about 5% of the apertures in the nonwoven ply will fall outside these size ranges. For apertures which are not circular in shape, the "diameter" of the aperture refers to the diameter of a circular opening having the same surface area as the opening of the non-circular shaped aperture. Within the nonwoven ply, the apertures will generally occur at a frequency of from about 0.5 to 20 apertures per straight linear centimeter. More preferably, the apertures in the exterior surface will occur at a frequency of from about 1.5 to 12 apertures per straight linear centimeter The apertures must at least be placed within the nonwoven ply. Such apertures need not protrude completely through one surface of the nonwoven ply to the other. They, however, may do so. Additionally, apertures may or may not be placed the optional second layer of the substrate such that the article is apertured through it's entire volume. Apertures may be formed in the nonwoven ply of the water insoluble substrate as such a substrate, or layer thereof, is being formed or fabricated. Alternatively, apertures may be formed in the nonwoven ply after the substrate comprising the first layer has been completely formed. The nonwoven ply may comprise a variety of both natural and synthetic fibers or materials. As used herein, "natural" means that the materials are derived from plants, animals, insects or byproducts of plants, animals, and insects. The conventional base starting material is usually a fibrous web comprising any of the common synthetic or natural textile-length fibers, or combinations thereof Nonhmiting examples of natural materials useful in the present invention include, but are not limited to, silk fibers, keratin fibers and cellulosic fibers Nonhmitmg examples of keratin fibers include those selected from the group consisting of wool fibers, camel hair fibers, and the like Nonhmiting examples of cellulosic fibers include those selected from the group consisting of wood pulp fibers, cotton fibers, hemp fibers, jute fibers, flax fibers, and combinations thereof. Cellulosic fiber materials are preferred in the present invention. Nonhmiting examples of synthetic materials useful m the present invention include those selected from the group consisting of acetate fibers, acrylic fibers, cellulose ester fibers, modacrylic fibers, polyamide fibers, polyester fibers, polyolefin fibers, polyvinyl alcohol fibers, rayon fibers, polyethylene foam, polyurethane foam, and combinations thereof Examples of suitable synthetic materials include acrylics such as acπlan, creslan, and the acrylonitπle-based fiber, orlon; cellulose ester fibers such as cellulose acetate, arnel, and acele; polyamides such as nylons (e.g , nylon 6, nylon 66, nylon 610, and the like), polyesters such as fortrel, kodel, and the polyethylene terephthalate fiber, polybutylene terephalate fiber, dacron; polyolefins such as polypropylene, polyethylene; polyvinyl acetate fibers; polyurethane foams and combinations thereof.

Methods of making nonwovens are well known m the art Generally, these nonwovens can be made by air-laying, water-laying, meltblowmg, coforming, spunbond g, or carding processes m which the fibers or filaments are first cut to desired lengths from long strands, passed into a water or air stream, and then deposited onto a screen through which the fiber-laden air or water is passed The resulting layer, regardless of its method of production or composition, is then subjected to at least one of several types of bonding operations to anchor the individual fibers together to form a self-sustaining web. In the present invention the nonwoven plies can be prepared by a variety of processes including, but not limited to, air- entanglement, hydroentanglement, thermal bonding, and combinations of these processes Nonwoven plies made from synthetic materials useful the present invention can be obtained from a wide variety of commercial sources Nonhmiting examples of suitable nonwoven first layer mateπals useful herein include HEF 40-047, an apertured hydroentangled material containing about 50% rayon and 50% polyester, and having a basis weight of about 61 grams per square meter (gsm), available from Veratec, Inc , Walpole, MA, HEF 140-102, an apertured hydroentangled material containing about 50% rayon and 50% polyester, and having a basis weight of about 67 gsm, available from Veratec, Inc , Walpole, MA, Novonet® 149-616, a thermo-bonded grid patterned material containing about 100% polypropylene, and having a basis weight of about 60 gsm available from Veratec, Inc , Walpole, MA, Novonet® 149-801, a thermo-bonded grid patterned material containing about 69% rayon, about 25% polypropylene, and about 6% cotton, and having a basis weight of about 90 gsm, available from Veratec, Inc Walpole, MA, Novonet® 149-191, a thermo-bonded grid patterned material containing about 69% rayon, about 25% polypropylene, and about 6% cotton, and having a basis weight of about 120 gsm , available from Veratec, Inc Walpole, MA, HEF Nubtex® 149-801, a nubbed, apertured hydroentangled material, containing about 100% polyester, and having a basis weight of about 84 gsm , available from Veratec, Inc Walpole, MA, Keybak® 951V, a dry formed apertured material, containing about 75% rayon, about 25% acrylic fibers, and having a basis weight of about 51 gsm , available from Chicopee, New Brunswick, NJ, Keybak® 1368, an apertured material, containing about 75% rayon, about 25% polyester, and having a basis weight of about 47 gsm , available from Chicopee, New Brunswick, NJ, Duralace® 1236, an apertured, hydroentangled material, containing about 100% rayon, and having a basis weight from about 48 gsm to about 138 gsm, available from Chicopee, New Brunswick, NJ, Duralace® 5904, an apertured, hydroentangled material, containing about 100% polyester, and having a basis weight from about 48 gsm to about 138 gsm , available from Chicopee, New Brunswick, NJ, Chicopee® 5763, a carded hydroapertured material (8x6 apertures per inch, 3X2 apertures per cm), containing about 70% rayon, about 30% polyester, and a optionally a latex binder (Acrylate or EVA based) of up to about 5% w/w, and having a basis weight from about 60 gsm to about 90 gsm , available form Chicopee, New Brunswick, NJ, Chicopee® 9900 series (e g , Chicopee 9931, 62 gsm , 50/50 rayon/polyester, and Chicopee 9950 50 gsm , 50/50 rayon/polyester), a carded, hydroentangled material, containing a fiber composition of from 50% rayon/50% polyester to 0% rayon 100% polyester or 100% rayon 0% polyester, and having a basis weight of from about 36 gsm to about 84 gsm, available form Chicopee, New Brunswick, NJ, Sontara 8868, a hydroentangled material, containing about 50% cellulose and about 50% polyester, and having a basis weight of about 72 gsm , available from Dupont Chemical Coφ Prefeπed non-woven substrate mateπals have a basis weight of about from 24 gsm to about 96 gsm, more preferably from about 36 gsm to about 84 gsm , and most preferably from about 42 gsm to about 78 gsm The nonwoven ply may also be a polymeric mesh sponge as described in European Patent Application No. EP 702550A1 published March 27, 1996, which is incoφorated by reference herein in its entirety. Such polymeric mesh sponges comprise a plurality of plies of an extruded tubular netting mesh prepared from nylon or a strong flexible polymer, such as addition polymers of olefm monomers and polyamides of polycarboxy c acids The nonwoven plies may also comprise formed films and composite materials, l e , multiply materials containing formed films. Preferably, such formed films comprise plastics which tend to be soft to the skin. Suitable soft plastic formed films include, but are not limited to, polyolefins such as low density polyethylenes (LDPE) In such cases where the nonwoven plies comprise a plastic formed film, it is preferred that the nonwoven ply be apertured, e.g., macroapertured or microapertured, such that the ply is fluid permeable In one embodiment, the nonwoven ply comprises a plastic formed film which is only microapertured The surface aberrations of the microapertures, i.e., the male side, are preferably located on the interior surface of the second layer and preferably face toward the inside of the substrate, I e., toward the cleansing component/ therapeutic benefit component In certain embodiments which include apertures having petal-like edged surface aberrations, without being limited by theory, it is believed that when the surface aberrations of the apertures face toward the surfactant-containing cleansing component/ therapeutic benefit component, the application of pressure by the hand to the article allows the petal-like edges of the surface aberrations to fold inward thereby creating numerous valves on the interior surface of the layer which in effect meter out the cleansing component/ therapeutic benefit component contained within the article thereby extending the article's useful life. In another embodiment, the nonwoven ply compπses a plastic formed film which is both microapertured and macroapertured In such embodiments, the nonwoven ply is well-suited to contact the area to be cleansed given the cloth-like feel of such microapertured films. Preferably, in such an embodiment, the surface aberrations of the microapertures face opposite of the surface aberrations of the macroapertures on the nonwoven first layer In such an instance, it is believed that the macroapertures maximize the overall wetting/lathering of the article by the three-dimensional thickness formed from the surface aberrations which are under constant compression and decompression during the use of the article thereby creating lathering bellows. In any case, when the nonwoven ply of the first layer comprises a formed film, the ply preferably has at least about 100 apertures/cm 2 , more preferably at least 500 apertures/cm 2 , even still more preferably at least about 1000 apertures/cm 2 , and most preferably at least about 1500 apertures/cm 2 of the substrate.

consisting of nonwovens, wovens, sponges (e g , natural and synthetic), formed films, battings, and combinations thereof This second layer is useful for providing a different texture side to the article of the present invention as well as acting as an additional carrier for the cleansing component Nonwovens suitable for use in the second layer include but are not limited to those discussed above in the Nonwoven First Layer section In addition, suitable wovens include, but are not limited to, polymeric nets (scrims) Scrims comprise fibers such as those mentioned as suitable for the nonwoven ply of the first layer A preferred second layer comprises batting which comprises synthetic fibers Preferred synthetic fibers may be selected from the group consisting of nylon fibers, rayon fibers, polyolefin fibers, polyester fibers, and combinations thereof Preferred polyolefin fibers are fibers selected from the group consisting of polyethylene, polypropylene, polybutylene, polypentene, and combinations and copolymers thereof More preferred polyolefin fibers are fibers selected from the group consisting of polyethylene, polypropylene, and combinations and copolymers thereof Preferred polyester fibers are fibers selected from the group consisting of polyethylene terephthalate, polybutylene terephthalate, polycyclohexylenedimethylene terephthalate, and combinations and copolymers thereof More preferred polyester fibers are fibers selected from the group consisting of polyethylene terephthalate, polybutylene terephthalate, and combinations and copolymers thereof Most preferred synthetic fibers comprise solid staple polyester fibers which comprise polyethylene terephthalate homopolymers Suitable synthetic materials may include solid single component (l e , chemically homogeneous) and multicomponent (e g , biconstituent or multiconstituent) synthetic fibers, l e , more than one type of material making up each fiber Alternatively, the synthetic fibers can comprise two or more distinct filament types, e g , two filament types are contained within a bicomponent or dual component fiber Such bicomponent fibers may have a core-sheath configuration or a side-by-side configuration In either instance, the first layer may comprise either a combination of fibers comprising the above-listed materials or fibers which themselves comprise a combination of the above-listed materials For the core-sheath fibers, preferably, the cores comprise materials selected from the group consisting of polyesters, polyolefins having a T g of at least about 10°C higher than the sheath material, and combinations thereof Conversely, the sheaths of the bicomponent fibers preferably comprise materials selected from the group consisting of polyolefins having a T g of at

configuration, core-sheath configuration, or solid single component configuration, the fibers of the first layer may exhibit a helical or spiral or crimped configuration, particularly the bicomponent type fibers In another preferred embodiment the second layer comprises a woven comprising a synthetic material comprising nylon fibers A more preferred synthetic material comprises nylon fibers formed into a scrim layer having additional nylon fibers bonded thereto such that the additional fibers form arcs on the scrim layer Additionally, the first layer and any additional layers, including the optional second layer, are preferably bonded to one another in order to maintain the integrity of the article This bonding may consist of spot bonding (e g , hot point bonding), continuous joining (e g , laminated, etc ) or in a discontinuous pattern, or by bonding at the external edges (or periphery) of the layers and/or at discrete loci or combinations thereof The bonding may also be arranged such that geometric shapes and patterns, e g diamonds, circles, squares, etc , are created on the exterior surfaces of the layers and the resulting article It is also envisioned in the articles of the present invention that the first layer and any additional layers may be surface modified to form single composite layer having 2 sides with different textures Thus, in effect, the water insoluble substrate can be construed as comprising a single composite layer with dual textured sides or surfaces In any event, it is preferred that the bonded area present between the nonwoven first layer and additional layers be not greater than about 50% of the total surface area of the layers, preferably not greater than about 15%, more preferably not greater than about 10%, and most preferably not greater than about 8% Each of the layers discussed herein comprises at least two surfaces, namely an interior surface and an exterior surface, each of which may have the same or different texture and abrasiveness Preferably, the articles of the present invention comprise substrates and therefore layers which are soft to the sk However, differing texture substrates can result from the use of different combinations of materials or from the use of different manufacturing processes or a combination thereof For instance, a dual textured water insoluble substrate can be made to provide a personal care article with the advantage of having a more abrasive side for exfoliation and a softer, absorbent side for gentle cleansing and/or therapeutic treatment In addition, the separate layers of the substrate can be manufactured to have different colors, thereby helping the user to further distinguish the surfaces Furthermore, each of the layers of the articles as well as the articles themselves may be made into a wide variety of shapes and forms including flat pads, thick pads, thin sheets, ball-shaped implements, irregularly shaped implements The exact size of the layers will depend upon the desired use and characteristics of the article and may range in surface area size from about a square inch to about hundreds of square inches Especially convenient layer and article shapes include, but are not limited to, square, circular, rectangular, hourglass, mitt-type or oval shapes having a surface area of from about 5 in 2 to about 200 in 2 , preferably from about 6 in 2 to about 120 in 2 , and more preferably from about 15 in 2 to about 100 in 2 , and a thickness of from about 0 5 mm to about 50 mm, preferably from about 1 mm to about 25 mm, and more preferably from about 2 mm to about 20 mm CLEANSING COMPONENT The articles of the present invention comprise a cleansing component that further compπses one or more surfactants The cleansing component is disposed onto disposed adjacent to the water insoluble substrate In certain embodiments, the cleansing component is impregnated into the water insoluble substrate In another embodiment, the cleansing component is deposited onto either or both surfaces of the substrate The articles of the present invention comprise from about 10% to about 1,000%, preferably from about 50% to about 600%, and more preferably from about 100% to about 250%, based on the weight of the water insoluble substrate, of the surfactant Also, the articles of the present invention preferably comprise at least about 1 gram, by weight of the water insoluble substrate, of a surfactant Thus, the cleansing component may be added to the substrate without requiring a drying process The surfactants of the cleansing component are preferably lathering surfactants As used herein, "lathering surfactant" means a surfactant, which when combined with water and mechanically agitated generates a foam or lather Such surfactants are preferred since increased lather is important to consumers as an indication of cleansing effectiveness In certain embodiments, the surfactants or combinations of surfactants are mild As used herein, "mild" means that the surfactants as well as to the articles of the present invention demonstrate skin mildness comparable to a mild alkyl glyceryl ether sulfonate (AGS) surfactant based synthetic bar, I e , synbar Methods for measuring mildness, or inversely the imtancy, of surfactant containing articles, are based on a skm barrier destruction test In this test, the milder the surfactant, the

Prior to measurement the crystal is cleaned with a suitable solvent. The sample is placed onto the ATR crystal and held under constant 4 kilogram weight Experimental Procedure. (1) Measure the reference (background) spectrum of the cleaned, air dried cell (2) First, select a substrate with no benefit agents applied to it, the substrate selected comprising the external surface of the article. Place substrate on top of the ATR crystal., external surface against the crystal. First lay the substrate flat on the measuring platform. Then place a 4 kg weight on top of the substrate Then, measure the spectrum (typically 100 scans at 4 cm "1 resolution). The substrate acts as an internal standard because the absorbancy of the substrate alone is thus identified. Identify the mam substrate peaks and wavenumbers (3) Repeat the procedure for the substrate of the article with benefit agent applied to it. Identify the primary benefit agent's peak heights, which are the highest observed peaks that either do not correspond to a substrate peak as observed previously; or which may correspond to a previously observed substrate peak but which exhibit the greatest percentage increase in absorbance due to presence of the conditioning agent. Record the wavenumber and absorbance of several benefit agent peaks. (4) Select the substrate peak from the spectra determined in step 3 which occurs at a wavenumber determined in step 2, but which does not correspond to one of the primary benefit agent peaks selected in step 3. Record the wavenumber selected and the absorbance from the absorbance spectrum in step 3. (5) Calculate the ratio of each benefit agent's peak height determined in step 3 to the substrate's peak height determined in step 4. The highest number of the group represents the surface to saturation ratio for the article. The following contain some examples: ♦ Substrates of these types are readily available, for example from PGI Nonwovens, Benson, NC Moisture Retention Methodology As described above, the articles of the present invention are considered to be "substantially dry" As used herein, "substantially dry" means that the articles of the present invention exhibit a Moisture Retention of less than about 0.95 gms, preferably less than about 0.75 gms, even more preferably, less than about 0 5 gms, even more preferably less than about 0 25 gms, even still more preferably less than about 0.15 gms, and most preferably, less than about 0 1 gms The Moisture Retention is indicative of the dry feel that users perceive upon touching the articles of the present invention as opposed to the feel of "wet" wipes In order to determine the Moisture Retention of the present articles and other disposable substrate- based products, the following equipment and mateπals are needed. Next, weigh two paper towels separately and record each weight. Place one paper towel on flat surface (e g lab bench) Place the sample article on top of that towel Place the other paper towel on top of sample article. Next, place the Lexan and then the 2000g weιght(s) on top of the sandwiched sample article Wait 1 minute. After the minute, remove weιght(s) and Lexan. Weigh the top and bottom paper towel and record the weight. Calculate the Moisture Retention by subtracting the initial paper towel weight from the final weight (after 1 minute) for both the top and bottom paper towels Add the weight differences obtained for the top and bottom paper towels Assuming multiple articles are tested, average the total weight differences to obtain the Moisture Retention.
