Description

Technical field:

The present invention relates to a thoroughly dry, disposable personal cleansing product suitable for both cleansing and conditioning the skin or hair, and more particularly to a disposable cleansing and conditioning product having a substrate, preferably comprising multiple layers. These products are used by the consumer after wetting the dry product with water. The article comprises a water-insoluble substrate having at least a first portion that is wet extensible, and at least a second portion that is less wet extensible than said first portion, and a conditioning component. The products of the present invention preferably further comprise a conditioning component.

The use of a substrate improves foaming at low surfactant levels, enhances cleaning and peeling, optimizes delivery and deposition of conditioning ingredients, and provides desirable properties such as texture, strength and volume. Consequently, the invention provides efficient cleaning using low, and thus less irritant, surfactant levels, while providing better treatment benefits with a substrate having the desired properties.

The invention also encompasses products containing various active ingredients delivered to the skin or hair.

The invention also encompasses a method of consistently applying conditioning agents to the skin or hair.

The invention also encompasses a method of cleansing and moisturizing the skin or hair using the articles of the present invention, as well as methods of making the articles.

BACKGROUND OF THE INVENTION:

Personal cleaning products are sold in various forms, such as soaps, creams, solutions and gels. In order to be acceptable to consumers, these cleaning formulations attempt to satisfy a number of criteria. These criteria include cleansing effectiveness, skin feel, softness to the skin, hair and eye mucosa, and amount of foam. The ideal personal cleanser should gently cleanse the skin or hair, cause little or no irritation, and should not leave the skin or hair too dry when used frequently.

F

However, these traditional forms of personal cleansing products have the basic problem of balancing cleaning performance against the benefits of treatment. One solution to this problem is to use separately cleaning and conditioning products. However, this is not always appropriate or practical and many consumers would prefer to use a single product that is able to both cleanse and condition the skin or hair. The conditioning ingredients are difficult to formulate in typical cleaning compositions because few conditioners are compatible with surfactants, resulting in an undesirable inhomogeneous composition. In order to obtain a homogeneous mixture with the conditioning ingredients and to prevent the loss of conditioning ingredients prior to deposition, additional ingredients such as emulsifiers, thickeners and gelling agents are often added to suspend the conditioning ingredients in the surfactant mixture. This results in an aesthetically pleasing homogeneous mixture, but often also poor deposition of conditioning ingredients, as conditioners are emulsified and are not effectively released during cleaning. Many conditioning ingredients also have the disadvantage of suppressing the formation of foam. Suppression of foaming is a problem because many consumers want cleaning products that provide rich, soft and plentiful foam.

Thus, it is apparent that conventional cleaning products that attempt to combine surfactants and conditioning agents suffer from disadvantages inherent in the incompatibility of surfactants and conditioners. There is undoubtedly a need to develop cleaning systems that provide efficient cleaning while still providing sufficient treatment in a single product.

It is also highly desirable to deliver the benefits of cleaning and conditioning from a disposable product. Disposable products are convenient as they avoid the need to carry bulky bottles, pieces, containers, tubes and other forms of cleaning and conditioning products. Disposable products are also a more hygienic alternative to the use of sponges, washcloths or other cleaning tools designed for multiple reuse since such tools produce bacterial growth, unpleasant odors and other unwanted properties associated with reuse.

In addition, the consumer habits of using disposable products having two surfaces have changed considerably. When such products are ready for use, consumers generally wet the product and then "foam" it before contact with their skin or hair. "Foaming" is achieved by rubbing the surfaces of the product together before using the product. When the foaming agent is first used in the foaming and the same surface is then used in contact with the skin or hair, deposition of the conditioning agents is greatly reduced by emulsifying the conditioning agents with a surfactant. However, when the surfactant-free surface (e.g., the surfactant-containing surface) is rubbed against itself to form a foam and the surfactant-containing surface is then used to contact the skin or hair,

AND

thus maximum deposition of conditioning agents is achieved. When both surfaces of the article are impregnated with conditioning agents, the result may be equally volatile depositing. Maximum deposition of conditioning agents should be the result when an un foamed surface containing conditioning agents is in contact with the skin or hair.

Surprisingly, it has been found that when the conditioning component (combination of conditioning agents) has a lipid hardness value of at least 0.02 kg, the volatile deposition of the conditioning agents is greatly reduced. Increasing the hardness of the conditioning component is believed to reduce transfer within the substrate and also to reduce the emulsification of the conditioning agents by surfactants during the foaming step. As a result, a greater amount of conditioning agents remain available for mechanical transmission by skin or hair contact.

It is also highly desirable to provide a cleaning and conditioning product having washcloth properties. These desirable features can be realized in disposable products by providing suitable texture, height (caliper) and volume (volume per unit weight). Relatively high texture values are useful in helping clean skin and hair. Relatively high height and volume values are useful in providing volume for receiving and retaining liquids by the product. Such washcloth-like articles have a substrate that contains one or more materials or layers. The substrate may be pre-wetted with a wetting agent prior to use, or may optionally be combined with a liquid at the time of use of the article. Pre-moistened wiping products are also referred to as "wet wipes" and "bath towels".

One way of providing the texture and volume of a washcloth-like article is by combining layers having different properties. U.S. Pat. No. 4,469,735 to Trokhan, issued Sep. 4, 1984, discloses a multi-layered tissue handkerchief having a wet microcontracted confinement paper layer and a dry creped confined paper layer. The portions of the restricted layer are adhered to the limit layer. When the multi-layered product is wetted, the non-adhered portions of the restricted layer are folded in the Z-direction to provide texture and volume.

Although the structure in U.S. Pat. No. 4,469,735 provides the advantage of texture and volume when wetted, requiring the use of wet microcontraction processes on a paper machine in order to prepare these structures. Structures in U.S. Pat. No. 4,469,735 further discloses wet heights that are lower than the corresponding dry heights.

Surprisingly, it has been found in the present invention that products can be developed to provide efficient cleaning and consistent treatment with a suitable, inexpensive and hygienic personal disposable cleaning product having desirable washcloth properties. The present invention provides the convenience of not needing to use separate cleansing and regulating »· ^4» · ♦ '► ⁴ • · · · · · product. The present invention is highly convenient in use since the article is in the form of a thoroughly dry article that is moistened before use.

The present invention relates to a dry, disposable personal cleansing product suitable for both cleansing and conditioning the skin or hair. These products are used by the consumer after wetting the dry product with water. The article comprises a water-insoluble substrate having at least a first portion that is wet extensible and at least a second portion that is less wet extensible than said first portion, and a conditioning component having a lipid hardness value of at least 0.02 kg. Without being limited by theory, it is believed that the substrate increases foaming at low surfactant levels, enhances cleaning and peeling, and optimizes delivery and consistent deposition of conditioning ingredients. It is also believed that when the conditioning component has a lipid hardness value of at least 0.02 kg, it provides a more efficient and consistent deposition of the conditioning agents on the skin or hair. As a result, the present invention provides efficient cleaning using low, and therefore less irritating, surfactant levels while providing better treatment benefits in terms of consistency and efficiency. It has also been found that these products are useful in delivering a wide variety of active ingredients to the skin or hair during the cleansing process.

Detailed description of the invention:

The personal cleansing products of the present invention are highly effective in cleansing the skin or hair, although at the same time provide effective deposition of conditioning agents. These products may also contain other non-conditioning active ingredients to be applied to the skin or hair.

Without being limited by theory, it is believed that the substrate contributes significantly to the formation of foam and to the deposition of conditioning agents and other active ingredients. It is believed that increased foaming and depositing is the result of the surface action of the substrate. As a result, milder and substantially lower amounts of surfactants can be used. It is believed that the reduced amount of surfactant required is related to the reduction in the drying effect of the surfactants on the skin or hair. In addition, the limited amount of surfactant significantly reduces the inhibitory effect (eg, emulsification or direct removal by surfactant) that surfactants exhibit due to the deposition of conditioning agents.

Without being limited by theory, it is believed that the substrate also increases the deposition of conditioning agents and active ingredients. Since the invention is in dry form, it does not require emulsifiers that can

4444 444 44 444 44 44 inhibit the deposition of conditioning agents and active ingredients. Since skin conditioners and active ingredients are dried on or impregnated into the substrate, they are additionally transferred directly to the skin or hair by contacting the surface of the moistened article with the skin.

The substrate also improves cleaning. The substrate may have different textures on each side, e.g., rough and soft sides. The substrate acts as an effective foaming and peeling tool. By physical contact with the skin or hair, the substrate significantly helps in cleaning and removing dirt, makeup, dead skin and other damaged tissues.

Finally, a substrate having at least a portion that is extensible in the wet provides the desired washcloth properties (e.g., correct texture, height and volume). It is also believed that these individual types of substrates increase foam formation.

It is also believed that if the conditioning component has a lipid hardness value of at least 0.02 kg, it provides consistent deposition of conditioning agents on the skin or hair due to reduced transfer within the substrate as well as reducing emulsification of the conditioning agents by surfactants during the foaming step.

By "foaming surfactant" is meant a surfactant which, when combined with water and mechanically mixed, forms a foam or suds. These surfactants should preferably be mild, meaning that these surfactants provide effective cleaning or cleaning benefits, but do not dry the skin or hair too much (eg by too much removal of natural fat and / or moisture) and still meet the foaming criteria described above.

The term " foaming product " or " foaming product " as used herein means that the product or product contains enough surfactants described herein to produce > 30 ml foam volume as described in the foam volume testing. These foam volume measurements are made with medium hard water (137-171 mg / L) at 95 ° C.

The term "disposable", as used herein in the ordinary sense, means a product that is disposed of or discarded after single use.

The term "conditioning component" as used herein means a combination of conditioning agents. This combination also includes lipid-hardening agents.

The term " water activated " as used herein means that the present invention is presented to the user in dry form to be used after being wetted with water. These products have been found to produce foam or are "activated" by contacting them with water and then further exposing the product to mechanical forces such as friction.

The term "thoroughly dry" as used herein means that the product is thoroughly dewatered before use and generally appears to be dry to the touch. Product of the present invention

Thus, generally, it will contain less than 10% by weight of water, preferably less than 5% by weight of water, and even more preferably less than 1% by weight of water. weighted water, measured in a dry environment, eg at low humidity. One skilled in the art should recognize that the water content of an article, such as in the present invention, may vary depending on the relative humidity of the environment.

The term "Fine" as used herein with respect to foaming surfactants and products of the present invention means that the products of the present invention exhibit skin softness comparable to a synthetic soap bar, i.e., a fine alkyl glyceryl ether sulfonate (AGS) surfactant based. Methods for measuring the softness, or vice versa, of the surfactant-containing articles are based on a skin barrier destruction test. In this test, the finer the surfactant, the less the skin barrier is destroyed. The skin barrier destruction assay is measured by the relative amount of radiolabelled water (tritium, ³ H-H2O) that passes from the test solution through the skin to the physiological buffer solution contained in the diffusate reservoir. This test is described by TJ Franz in J. Invest. Dermatol. 1975, 64, 190-195 and in U.S. Pat. No. 4,673,525 to Small et al., issued June 16, 1987, both of which are incorporated by reference in their entirety. Other methodologies for testing the fineness of a surfactant are well known to those skilled in the art and can also be used.

The term "deposition consistency" as used herein means that the deposition of conditioning agents forming the conditioning component will be relatively uniform no matter how the user prepares for use and actually uses this cleaning and conditioning product (eg foaming the side of the treatment component substrate versus foaming of the substrate side with the surfactant). The products of the present invention will have a depositing consistency of greater than 60%, preferably greater than 65%, even more preferably greater than 70% and most preferably greater than 75%. Deposition consistency measurement is the quotient obtained by dividing the amount of conditioning agents deposited under "non-ideal foaming and use" and the amount of conditioning agents deposited under "ideal foaming and use". Non-ideal foaming as used herein means that foaming is achieved by rubbing the surface of the conditioning agent product against or against each other and then contacting the skin or hair with the same surface. This causes ineffective deposition of the conditioning agents since some of the conditioning agents are emulsified by the surfactant. Ideal foaming as used herein means that foaming is achieved by rubbing the surface of the surfactant-containing article against or against each other and then contacting the skin or hair with the surface containing the conditioning component. The same starting points would be applied when both substrate surfaces were treated with fr fr fr fr fr fr fr fr 9 fr 99 fr 99 fr 99 Frifying agents (eg deposition obtained by foaming and contacting the skin with the same foamed surface containing the emulsified formulations). conditioning agents versus skin contact with a foamed surface containing unemulsified conditioning agents). Deposition consistency is maximized when the lipid hardness of the conditioning components is greater than 0.02 kg.

The personal care products of the present invention comprise the following essential components: (A) a water insoluble substrate, wherein at least a first portion of said substrate is wet extensible and at least a second portion of said substrate is less extensible wet than said first portion, and (B) at least one foaming agent a surfactant added to or impregnated into the substrate. The articles of the present invention may further comprise a conditioning component added to or impregnated into the substrate.

A water-insoluble substrate having at least one wet-extensible portion

The articles of the present invention comprise a water-insoluble substrate, wherein at least a first portion of said substrate is wet extensible and at least a second portion of said substrate is less extensible wet than said first portion. By " water insoluble " is meant that the substrate does not dissolve in the aqueous does not readily break upon immersion in water. By wet-extensible is meant that the material, when wetted, tends to elongate in at least one direction. The extensibility test is shown below. The water-insoluble substrate is a tool or means for delivering a foaming surfactant and conditioning the components of the present invention to the skin or hair to be cleaned and treated. Without being limited by theory, it is believed that the substrate, as a means of transmitting mechanical forces and providing agitation, provides a foaming effect and also assists in depositing the conditioning component.

One embodiment of a water-insoluble substrate having at least one wet extensible portion is demonstrated in Figures 1 to 3. In this embodiment, the present invention includes a disposable wiping product with a multi-layer 20. Figures 1 to 3 show a two-layer embodiment of the present invention. Alternatively, the disposable wiping article may comprise more than two layers.

The disposable cleansing and conditioning article 20 comprises a substrate generally designated by reference numeral 22. The substrate 22 comprises a first layer 100 and a second layer 200. The first layer 100 is extensible, and particularly wet extensible, eg, the first layer is extensible in wet. By " wet extensible " is meant that the material tends to elongate in at least one direction when wetted. "Wetted" usually refers to wetting with aqueous solutions, such as e.g.

• · • ·

water, which are capable of inducing stretching of the first layer. For example, water releases creping in the shortened paper, causing the paper to expand in at least one direction in the plane of the paper. Without being limited by theory, the release of creping may result from the loss of hydrogen bonds in the paper structure due to the presence of water. Any liquid, mixture, or solution that could cause this creep release could be considered as a "wetting" of the product. The second layer 200 is relatively less wet extensible than the first layer 100. The extensibility is measured according to the "wet extensibility test" described below and is given in percent.

The selected portions of the first layer 100 are connected, directly or indirectly, to the second layer 200 to prevent stretching of the first layer in the plane of the first layer. In Figures 1 and 2, selected portions of the first layer 100 are joined to the second layer 200 to provide continuous joined areas designated 110 and separate unconnected areas 114.

In the preferred embodiment shown in Figure 1, the interconnected regions 110 are shown as a continuous network of trapezoids forming generally rhombic unconnected regions 114. The width and distance of the trapezoids of the interconnected regions 110 may be adjusted to the desired size and distance of the rhombic unconnected regions 114. any template resulting in unconnected regions of virtually unlimited geometric shapes including eg squares, rectangles and triangles. The mesh may not be completely continuous and also may not be bounded by a mesh of straight or uniform lines, but may, for example, be a mesh resulting in circular, oval or other non-polygonal geometric shapes. An adhesive, such as a hot melt adhesive, designated 300 in Figures 1 to 3, may be used to bond the first layer 100 and the second layer 200.

When the first layer is wetted, it tends to expand along one or more directions in the plane of the first layer. (The plane of the first layer is parallel to the plane of Figure 1). However, due to the relatively low wet extensibility of the second layer 200, the second layer limits the stretching of the first layer 100 in the plane of the first layer. As a result, the unconnected regions 114 of the first layer 100 deform, such as by bulging or corrugation in a Z-direction perpendicular to the plane of the first layer 100.

Figure 5A is an illustration of a cross-section of the cleaning and conditioning article 20 prior to wetting of the first layer 100. As shown in Figure 5A, the wiping article is typically flat prior to wetting. Figure 5B is a cross-sectional illustration similar to Figure 5A, but shows the article 20 after wetting the first layer 100. Figure 5B shows deformations outside the first layer 100 after wetting the first layer 100. The Z-direction is indicated in Figures 5A and 5B. Deformation of the moistened first layer 100 provides an article 20 with raised ridges 120 that increase texture, height, and height.

product volume 20 wet. The raised ridges 120 also provide bags 150 disposed between the unbonded portions of the first layer 100 and the underlying portions of the second layer. In particular, the article 20 has a wet height to dry height ratio of greater than 1.0, preferably at least 1.1, more preferably at least 1.2, and most preferably at least 1.4. The wet-to-dry-height ratio is measured from the height of the article 20 after wetting relative to the height of the dry product 20 before wetting. The wet-to-dry-height ratio is measured according to the "wet-to-dry-height ratio" procedure below.

In a preferred embodiment, as shown in Figure 1, the first layer 100 is apertured, the first layer 100 comprising a plurality of apertures 102 that extend through the height of the first layer 100. The apertures that are not necessary to practice the invention add the desired texture and volume of the wiping article. 20 size. In Figures 1-3, clarity apertures 102 are shown only in a portion of the first layer 100. When a perforated first layer is used, deformation of the moistened first layer 100 again provides the article 20 with raised ridges 120 that increase the texture, height and volume of the article 20 beyond. wet. However, in this embodiment, the raised ridges 120 have apertures 102 that provide leakage channels through which liquids and / or small particles may enter the bags 150.

In addition, since the article 20 is used with or contains a foaming agent, such as a surfactant, the apertures 102 can assist in incorporating air during the foaming process, thereby improving foam formation. For example, a portion of the article 20 may be coated or otherwise treated with a surfactant, as described in more detail below. The article 20 may be wetted with water to activate the surfactant, and the passage of air through the apertures 102 during use of the article (eg, washing or wiping) may aid in the formation of foam.

The size and number of holes 102 may affect the rate of foam formation and the quality of the foam formed. A relatively small number of relatively large apertures 102 will tend to reduce the time required to produce foam, but will produce relatively large transparent bubbles of foam. On the other hand, a relatively larger number of relatively smaller apertures 102 will result in a reduced bubble size, thereby increasing the softness and opacity of the foam, but increasing the time required for foam formation. 2 to 158 holes per centimeter can provide suitable foam quality and rate of foam formation.

When the apertured first layer 100 is used, another advantage can be recognized. As shown in Figure 5B, in addition to forming the raised ridges 120, the extension of the first layer 100 around the apertures 102 constitutes what can best be described as spikes 106, or surface irregularities created by the apertures 102. The spikes 106 add surface texture to the perforated surface 22 layers · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · ·

100. This added texture may be modified by adjusting the size and distance of the apertures 102 as desired.

Also shown in Figure 3 is another variant of the arrangement of joined and unconnected regions. In said embodiment, the bonded regions 110 are generally parallel, spaced apart regions that extend along the entire length of the article 20, and define generally parallel, spaced apart bonded regions 114 of the first layer 100. The bonded regions 114 extend along the entire length of the article 20 in Figure 3. For the bonding of the first layer 100 and the second layer 200, an adhesive designated by numerical reference 300 in Figures 1 and 2 and by numerical reference 300, 310A-310D in Figure 3 can be used.

In a presently preferred embodiment, the napkin 20 of the present invention comprises an apertured cellulosic paper first layer bonded to a synthetic nonwoven layer by a continuous network of trapezoids defining rhombic unbonded areas. This combination of materials and bonding methods and stencils provides a preferred wipe that exhibits increased texture and wetted volume on one side, while maintaining a relatively soft delicacy on the other hand and having a wet height greater than a dry height.

In addition to the above description, it has been found that an additional processing step involving heating the substrate after bonding further improves texture and volume as well as the overall aesthetic quality of the wipe. Without being limited by theory, it is believed that the heating process causes the thermoplastic adhesive to shrink, thereby further causing the first layer to deform in a direction out of its plane (Z-direction) as well as the second layer. By shrinking in the plane of the napkin product, both layers undergo a height increase in the Z-direction, thereby increasing the overall height with a pleasant quilted appearance.

For example, a napkin that is bonded with a hot melt adhesive EVA (one suitable adhesive is a hot melt adhesive commercially available as H1382-01 from Ato-Findley Adhesives of Wauwatosa, Wisconsin) may increase the height by 10 to 10 after additional hot laminating. 20%. In this case, a suitable hot melt adhesive is applied and the resulting product is cooled to room temperature. Thereafter, a heat treatment may be performed, e.g. raising the temperature to 100 ° C for 20 seconds is sufficient to initiate the shrinkage of the polymer network. Without being limited by theory, it is believed that in order for this process to be effective, the adhesive bond template must be a continuous or substantially continuous network. Separate binding sites cannot shrink sufficiently to improve the appearance of the article.

Referring in more detail to the components of the article 20, suitable materials from which the first layer 100 may be formed include shortened (e.g., creped) wet laid paper webs. Other suitable materials may include woven materials, nonwoven materials, foam, webs and the like.

The first layer 100 should be designed to have a wet extensibility of at least 4%, more preferably at least 10% and even more preferably at least 20%. In one embodiment, the first layer has a wet extensibility of 25%. The difference between the extensibility of the first and second wet layers (the extensibility of the second wet layer subtracted from the extensibility of the first wet layer) is preferably at least 4%, more preferably at least 10% and even more preferably at least 25%.

The fibers or threads of the first layer 100 may be natural (e.g., cellulosic fibers such as pulp fibers, cotton liners, and bagasse fibers) or synthetic (e.g. polyolefins, rayon, polyamides or polyesters) or combinations thereof.

In one preferred embodiment, the first layer 100 comprises a wet laid paper web of pulp fibers that is shortened by creping by at least 4%, more preferably by at least 10% and even more preferably by at least 20%. Referring to Figure 4, the first layer 100 includes crepe spines 105 corresponding to a shortening of the first layer 100. The machine direction (MD) direction and the cross machine direction (CD) are indicated in Figures 1 to 4. The longitudinal direction corresponds to the direction of production of the paper web of the first layer 100. The creping ridges 105 are perpendicular to the longitudinal direction and generally parallel to the transverse direction of the paper web of the first layer 100.

The paper web of the first layer 100 may have a basis weight between 15 and 65 g / m ² . In a preferred embodiment, the basis weight of the first layer is between 25 and 45 g / m and even more preferably, the basis weight of the first layer 100 is 35 g / m 2.

Without being limited by theory, it is believed that paper strength can substantially alter the overall appearance of the finished product. The amount of creping introduced into the first layer is directly proportional to the amount of areal stretching and hence the amount of height created after wetting. However, if the wet strength of the paper product is insufficient, the "bulging" may collapse to form a more "shrunken" product having a smaller height. Therefore, both creping and wet strength can be adjusted to provide a texture size based on the intended use of the article. Wet burst measurements were performed using a Thwing-Albert Burst Tester model number 1300-77, which tests the peak load of a fully wetted substrate. The test uses a ball diameter of 1.27 cm and a ball speed of 12.7 cm / min and clamps the test sample around a circle of 8.89 cm diameter perpendicular to the ball movement. Peak wet load tensile strength 9 9 9 9 9 9 9 9 9 9 999 9 99 999 9 9 99 99 999 9999 999999 99 9 · 9 9 · are between 100 to 1200 g per layer. More preferably between 400 to 700 g per layer and most preferably between 500 and 600 g per layer.

In a more preferred embodiment, the first layer 100 comprises an apertured wet-laid paper web of pulp fibers. The apertures 102 may be formed in the first layer 100 in any suitable manner. For example, the apertures 102 may be formed in the first layer during the formation of the paper web of the first layer 100 or optionally after the paper web of the first layer 100 is made. In one embodiment, the paper web of the first layer 100 is manufactured according to the teachings of one or more of the following U.S. Pat. patents, which are incorporated herein by reference: U.S. Pat. U.S. Patent No. 5,245,025, issued September 14, 1993 to Trokhan et al .; U.S. Pat. patent. No. 5,277,761, issued Jan. 11, 1994 to Phan et al. and U.S. Pat. No. 5,654,076, issued Aug. 5, 1997 to Trokhan et al. In particular, U.S. Pat. No. 5,277,761 in box 10 discloses the formation of a paper web having apertures.

The crepe first layer 100 should have between 1 to 47 holes 102 per cm and more preferably between 1 to 16 holes 102 per cm before wetting the first layer. Wetting the crepe paper web causes the web to be expanded, if not limited, in at least one direction, such as in the longitudinal direction, such that the number of holes 102 per cm after wetting may be less than the number of holes per cm before wetting. Similarly, when holes are formed in the paper web and the paper web is subsequently creped, the number of holes per cm before creping may be less than the number of holes per cm after creping. Similar are the relationships for the sizes of the paper net to the sizes after creping and before wetting.

The apertures 102 may comprise 15 to 75% of the total area of the first layer 100. The apertures 102 shown in Figure 2 are alternately arranged (alternately arranged in both longitudinal and transverse directions) in a repeating, regular pattern. In one embodiment, the first layer 100 comprises a paper web that is 25% dry creped (25% shortening) with a wet extensibility greater than 25% and which has 6-8 apertures 102 per cm ² , the apertures 102 having a length of 103 ( 4) from 0.04 to 0.07 cm and a width of 104 from 0.03 to 0.06 cm and a spacing between holes 106 of 0.02 to 0.03 cm.

The paper web is first produced by forming an aqueous batch in paper making. The batch comprises paper-forming fibers and may further comprise various additives. U.S. Pat. No. 5,223,096, issued June 29, 1993 to Phan et al. is incorporated herein by reference for the purpose of disclosing various pulps and additives in paper making.

A suitable paper web for making the first layer 100 can be made as described below. The paper batch is prepared from water and highly refined Kraft pulp derived from northern softwoods (NSK), ··· 9 99 9

9999 999 99 999 99 99 having a fiber density of 0.2% by weight (the weight of the dry fibers divided by the total weight of the charge is 0.002). A dry strength additive such as carboxymethyl cellulose (CMC) is added to 100% NSK batches in an amount of 2.27 kg solid CMC per tonne of dry fibers in papermaking. A wet strength additive such as Kymene 557H (available from Hercules, Inc. Of Wilmington, Del.) Is added to the batch in an amount of 12.7 kg solid Kymene per ton of dry fibers in papermaking.

Referring to Figure 6, the shaft is applied from the headbox 500 of the papermaking machine to the forming element 600 at a fiber density of 0.2%. The forming element 600 is in the form of an endless belt in Figure 6. A slurry of paper-forming fibers is applied to the forming element 600 and water from the slurry is drained through the forming element 600 to form a seed web of the paper-forming fibers indicated by the reference numeral 543 in Figure 6.

Figure 7 shows a portion of the molding member 600. The molding member 600 has two opposing sides. The side shown in Figure 7 is the side that contacts the fibers forming the paper of the forming web. A description of a forming element of the type shown in Figure 7 is provided in the above-mentioned U.S. Pat. U.S. Patent Nos. 5,245,025; 5,277,761 and 5,654,076.

The molding member 600 has flow restriction components in the form of resin protrusions 659. The shown molding member 600 comprises a patterned array of protrusions 659 associated with a reinforcing structure 657 that may include a perforated base such as a woven mesh or other apertured structure. The protuberances 659 extend over the reinforcing structure 657.

A suitable molding member 600 has 6 protrusions 659 per cm of molding member surface, with the protrusions 659 covering 35% of the molding member surface 600 as shown in Figure 7, and the protrusions extending 0.01 cm above the surface of the reinforcing structure 657. The protrusions may have a length in the longitudinal direction of 0.06 cm and a width in the transverse direction of 0.04 cm.

The reinforcing structure 657 is perfectly permeable to fluids, while the protrusions 659 are completely impermeable to fluids. Thus, both the fluid from the batch during the papermaking process flows through the forming element, and the fiber forming paper in the batch will be retained on the reinforcing structure 657, leaving holes in the germline 543 corresponding generally to the size, shape and location of the size, shape and location of the protuberances 659.

Referring back to Figure 6, the embryonic web 543 is transferred to a conventional dewatering felt 550 by means of a vacuum sensing blade 560. The web 543 is transferred to the felt 550 at a fiber density of 4%. The web 543 is guided through a felt 550 for engagement 570 formed between the vacuum pressure roller 572 and the Yankee drying drum 575. The belt 543 is dried on the drying drum.

Yankee 575 to a fiber density of 96% when the web is creped from a Yankee 575 drying drum using a creping rasp 577 having a bevel angle of 25 ^° and an impact angle of 81 °. To achieve a belt reduction of 25%, the belt is wound or wound at a speed that is 25% slower than the Yankee 575 Drying Drum (the winding speed is equal to 0.75 times the machining speed). The shortened belt may have a basis weight of 33 g / m ² and a height of 0.047-0.051 mm as measured by a limiting pressure of 14.73 g / cm 2 and a loading foot having a diameter of 5.08 cm. The resulting truncated strip may be used to form a first layer 100 having a wet extensibility of at least 25%.

Second layer:

To prevent stretching of the selected portions of the first layer 100 after wetting, the first layer 100 is bonded to the second layer 200. The second layer 200 has a lower wet extensibility than the first layer 100.

Suitable materials from which the second layer 200 may be formed include woven materials, nonwoven materials (including air-wound, water-wound, carded, and water-knitted non-woven materials) foams, webs, and the like. Particularly preferred materials are nonwoven webs having fibers or threads randomly distributed as in "air-wound" or certain "water-wound" processes, or with a degree of orientation such as in certain "wet-wound" and "carding" processes.

The selected portions of the first layer 100 are bonded directly (or indirectly, such as through a third component) to the second layer 200 by a predetermined binding style to provide a plurality of bonded and unbonded portions of the first layer 100. In FIGS. 110 and unconnected regions are designated 114. Both the first layer 100 and the second layer 200 may have a longitudinal direction, and the two layers may be joined such that the longitudinal direction of the first layer is generally parallel to the longitudinal direction of the second layer.

The first layer 100 and the second layer 200 may be joined in a suitable manner including, without limitation, adhesive bonding, mechanical bonding, thermal bonding, mechanical-thermal bonding, ultrasonic bonding, and combinations thereof. In a particularly preferred embodiment, the adhesive is applied by printing methods such as gravure printing, reverse gravure printing, screen printing, flexographic printing and the like. In one preferred embodiment, the hot melt EVA adhesive may be screen printed in a grid pattern generally shown in Figure 1. A suitable mesh for this embodiment is a Galvano mesh (16 fibers per cm) manufactured by Rothtec Engraving Corp., New Bedford, MA.

The adhesive is preferably water insoluble such that the article 20 can be moistened with water without delamination of the first and second layers. The adhesive is also preferably compatible with the surfactant. "Surfactant-compatible" means that the bonding properties of the adhesive are not impaired by the presence of the surfactant. Suitable adhesives include hot melt adhesives based on ethylene vinyl acetate (EVA). One suitable adhesive is a hot melt adhesive commercially available as H1382-01 from Ato-Findley Adhesives of Wauwatosa, Wisconsin.

Referring to Figures 1 and 2, a hot melt adhesive may be applied to the nonwoven second layer 200 in a continuous web that defines a discontinuous variety of discrete regions 114. In one preferred embodiment, as shown in Figure 1, the adhesive is applied in parallel, separately spaced lines in the first direction intersected by perpendicular, separately spaced lines in the second direction. The intersecting lines form a diamond pattern of unconnected areas in the final product. In the embodiment shown in Figure 1, the hot melt adhesive may be applied in lines having a width of 0.025 to 1.27 cm, preferably 0.127 to 0.178 cm. The spacing between adjacent lines of adhesive may be 0.508 to 5.08 cm, preferably 1.016 to 1.54 cm.

Referring to Figure 3, the hot melt adhesive may be applied to the nonwoven second layer 200 in strips that extend parallel to the longitudinal direction of the nonwoven second layer 200. The hot melt adhesive may be applied in strips 310 having a width W (Figure 3) of 0.318 Fr frfrfrfr frfr frfr frfr frfr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr 2.54 cm. The spacing D between adjacent adhesive strips may be 0.318 to 5.08 cm. In Figure 3, four strips 310A, 31B, 310C and 31DO are shown.

When the adhesive is applied as parallel strips, lines or strips, it can be applied to the nonwoven second layer 200 by a slot coating applicator. A suitable slot-type applicator is the Nordson MX series extruder die available from Nordson Company of Norcross, Ga. The H1382 adhesive mentioned above can be applied to the second layer 200 at 194 ° C and at an application level of 4.65 mg / cm ² . Immediately after applying the adhesive to the nonwoven second layer 200, the nonwoven layer 200 and the paper first layer 100 may be bonded together by compressing these layers 100 and 200 together with an adhesive disposed between the second layer 200 and the first layer 100. One suitable method of compressing the two layers 100 and 200 together is the passage of the two layers through a press formed by two rollers which are loaded to provide sufficient press pressure for coupling.

The resulting laminate of the first and second layers may have an average dry height of 0.0724 cm, an average wet height of 0.0815 cm, and a wet height to dry height ratio of 1.1. Dry height, wet height and wet height to dry height ratio are measured as described below under the heading "wet height to dry height ratio".

Wet extensibility test

The wet extensibility of the layer, such as layer 100 or layer 200, is determined by the following procedure. Prior to testing, the samples were conditioned for two hours at 38.9 ° C and 50% relative humidity.

Firstly, the direction of greatest wet extensibility in the plane of the layer is determined. For dry creped paper webs, this direction is parallel to the longitudinal direction and generally perpendicular to the crepe spines.

When the direction of greatest wet extensibility is unknown, this direction can be determined by cutting seven sheets from the sheet with sample lengths oriented between 0 and 90 ^° inclusive of the reference line drawn on the sheet. To determine the direction of greatest wet extensibility, the samples are then measured as explained below.

Once the direction of maximum wet extensibility is determined, 8 samples are cut to have a length of 17.78 cm measured parallel to the direction of greatest wet extensibility and a width of at least 2.54 cm. The samples are cut from the unconnected regions of layers 100 and 200, or if the unconnected regions having the above dimensions cannot be cut from the article 20, they are cut from the layers 100 and 200 prior to the mating of the layers. For each sample is

Each sample is completely moistened by immersing the sample for 30 seconds in distilled water in a water bath. Each sample is removed from the water bath and immediately supported so that it is suspended vertically so that the line through the two marks is generally vertical. The wet sample is supported so that the holder does not interfere with the extension between two marks (eg, a clamp that does not touch the sample between two marks). The wet sample length tested is the distance between two marks. The distance is measured within 30 seconds after removal of the sample from the water bath.

For each sample, the percent wet extensibility is calculated as:

Wet Extensibility of Sample = (Wet Length Tested - Initial Dry Test Length) / (Initial Dry Test Length) x 100

For example, for a wet length of 16.51 cm and an initial dry length of 12.70 cm, the wet extensibility ((16.51-12.70) / 12.70) x100 = 30%.

The wet extensibility of the samples is the average of 8 calculated wet extensibility values of the sample.

The ratio of wet height to dry height

The wet-to-dry-height ratio is measured using a ThwingAlbert Instrument Co. tester. Electronic Thickness Tester Model II according to the following procedure. Prior to testing, the samples were conditioned for two hours at 38.9 ° C and 50% relative humidity.

The dry height of the article 20 is measured by a cut-off pressure of 14.73 g / cm and a loading foot having a diameter of 5.08 cm. The dry height is measured for nine samples. The height for each sample is measured with a loading shoe centered on the unconnected region of the first layer 100. Nine height measurements are averaged to provide an average dry height.

Each sample is then moistened by immersion for 30 seconds in distilled water in a water bath. The sample is then removed from the water bath and drained vertically for 5 seconds. The wet sample height is then measured within 30 seconds after removal of the sample from the bath. The wet height is measured in the same position as the dry height previously measured. The nine wet height measurements are averaged to provide an average wet height. The ratio of wet height to dry height is the average wet height divided by the average dry height.

5) The test article is then opened with a non-dominant hand and a further 10 ml of water (medium hard 137-171 mg / L) at 95 ° C is added to the product with a 10 ml syringe or Brinkman pipette. The moistened product is rubbed again with the dominant hand (3 turns) using a slight pressure (eg 1.11 N) so that the test product crumples between the palms of the hand.

6) The test article is then opened and rubbed 5 times by grasping one edge of the article in the hand and rotating the hand holding the other side to further activate the foam.

7) The test article is then inverted and step 6 is repeated using the second hand.

8) The foam is then collected by holding the test product by hand with the flask provided and carefully wiping the foam from the test product with the other hand so that the foam is wiped off only from the test product. The foam of the test article is then placed in a measuring cylinder or beaker large enough to accommodate the foam formed. This procedure is repeated 5 times with the same test product and the foam from each repeat is collected in the same measuring cylinder or beaker. The total accumulated foam from these repetitions is referred to as the foam volume.

9) To achieve consistent results, the mean foam volume is reported as the average of three replicates of steps 1-8.

Solubility parameters are well known to chemists and are regularly used as an indicator to determine the compatibility and solubility of substances in the formulation process.

The solubility parameter of a chemical compound, δ, is defined as the square root of the cohesion energy energy density of that compound. Typically, the solubility parameter of a compound is calculated from the tabulated values of the additive heat dissipation of the groups and the molar volume of the components of the compound according to the equation:

{Ε {i

Στη i

1/2 where Σί Ej is the sum of additive contributions of the heat of discharge of groups and Σί m, is the sum of additive contributions of molar volume of groups.

The standard tabulated values of additive contributions of the heat and molar volume groups for a large number of atoms and atomic groups are collected in A.F.M. Barton's Handbook of Solubility Parameters, CRC Press, Chapter 6, Table 3, pp. 64-66 (1985), which is incorporated herein by reference in its entirety. The above solubility parameter equation is described in R.F. Fedors' A Method for Estimating Both Solubility Parameters and Molar Volumes of Liquids, Polymer Engineering and Science, Volume 14, No. 2, pp. 147-154 (February 1974), which is incorporated herein by reference in its entirety.

Solubility parameters are governed by the Mixtures Act so that the solubility parameter of a mixture of substances is given by the weighted arithmetic mean (ie, the weighted average value) of the solubility parameters of each component of such a mixture.

The term "emulsifying agent" as used herein means a combination of an internal phase comprising a water-soluble modifying agent that is shrouded in an external phase comprising a fat-soluble agent. In preferred embodiments, the modifying emulsion would further comprise an emulsifier. The conditioning emulsions comprise 0.25 to 150% by weight, preferably 0.5 to 100% by weight and more preferably 1 to 50% by weight of the total weight of said water-insoluble substrate. By treating emulsion is meant a combination of an inner phase comprising a water-soluble conditioning agent which is enveloped in an outer phase comprising a fat-soluble agent. In preferred embodiments, the conditioning emulsion would further comprise an emulsifier.

The conditioning emulsion comprises (i) an internal phase comprising a water-soluble modifying agent as described above, and (ii) an external phase comprising a fat-soluble modifying agent as described above in the lipid-soluble modifying agent section or further in the "Substances" section. used to increase the lipid hardness value ”. In other embodiments, the conditioning emulsion further comprises:

An emulsifier capable of forming an emulsion of said internal and external phases. Although an emulsifier capable of forming internal and external phase emulsions is preferred in the present invention, it is recognized in the art for skin care formulations that the water-soluble conditioning agent may be surrounded by a fat-soluble agent without emulsifier. As long as the water-soluble conditioning agent is surrounded by a fat-soluble agent, thereby preventing its elution during the purification process, the composition would be within the scope of the present invention.

The inner phase may optionally contain other water-soluble or dispersible substances which do not adversely affect the stability of the emulsion-modifying agent. One such substance is a water-soluble electrolyte. The dissolved electrolyte minimizes the tendency of the substances present in the lipid phase to dissolve also in the aqueous phase. Any electrolyte capable of imparting ionic strength to the internal phase can be used. Suitable electrolytes include water-soluble mono, di or trivalent inorganic salts, such as water-soluble halides, such as alkali and alkaline earth metal chlorides, nitrates and sulfates. Examples of such electrolytes include sodium chloride, calcium chloride, sodium sulfate, magnesium sulfate, and sodium bicarbonate. The electrolyte will typically be present in concentrations ranging from 1 to 20% by weight of the internal phase.

Other water-soluble or dispersible substances that may be present in the internal phase include thickeners and viscosity modifiers. Suitable thickeners and viscosity modifiers include water-soluble polyacrylic and hydrophobically modified polyacrylic resins such as Carbopol and Pemulen, starches such as corn starch, potato starch, maniotic starch, gums such as guar gum, acacia, cellulose ethers such as hydroxypropylcellulose, hydroxyethylcellulose, carboxymethylcellulose and others. These thickeners and viscosity modifiers may typically be present in concentrations ranging from 0.05 to 0.5% by weight of the internal phase.

Other water-soluble or dispersible substances that may be present in the internal aqueous phase include polycationic polymers to provide steric stabilization at the water-lipid interface and non-ionic polymers that also stabilize the water-lipid emulsion. Suitable polycationic polymers include Reten 201, Kymene 557H® and Acco 7112. Suitable non-ionic polymers include polyethylene glycols (PEG) such as Carbowax. These polycationic and non-ionic polymers will typically be present at a concentration ranging from 0.1 to 1.0% by weight of the internal phase.

Lipid hardness value

In embodiments further comprising a conditioning component, the article will preferably have a minimum lipid hardness value of 0.02 kg. The lipid hardness value is a measure of the physical hardness of the combination of all conditioning agents in the conditioning component. Increasing lipid hardness is believed to increase the consistency of deposition of conditioning agents despite the differences in foaming technique used by the consumer. It is believed that increasing the hardness of the conditioning component reduces the transfer within the substrate and also reduces the emulsification of the conditioning agents by the surfactant during foaming. As a result, a greater number of conditioning agents are available for mechanical transmission by skin or hair contact.

The conditioning component of the present invention has a lipid hardness value greater than 0.02 kg, preferably greater than 0.05 kg, and more preferably greater than 0.10 kg. The lipid hardness value of the conditioning component should preferably not be greater than 5.00 kg, more preferably 4.00 kg and most preferably 3.00 kg, as hardness levels above these points may negatively affect the deposition of conditioning agents in the conditioning component on the skin or hair.

Lipid hardness test

The lipid hardness value is measured by a test traditionally used to measure the hardness of the soap bar. The Chatillon force gauge is used to measure the hardness value of 155.5 to 248.8 g of the sample conditioning component. To obtain an average value, several records are taken, each for a fresh sample. Chatillon force gauge model no. DFIS 100 is manufactured by Chatillon Corporation, located in Greensboro, North Carolina.

In the present invention, the weight ratio of foaming surfactant to conditioning agent is less than 40: 7, preferably less than 5: 1, more preferably less than 2.5: 1 and even more preferably less than 1: 1.

In certain embodiments of the present invention, a cleaning and conditioning component is defined which comprises a foaming surfactant and a conditioning component further comprising a fat-soluble conditioning agent and a water-soluble conditioning agent, wherein the foaming surfactant comprises 1 to 75% by weight, preferably 10 up to 65% by weight and more preferably 15 to 45% by weight of the cleaning and conditioning component and the conditioning component comprise 15 to 99% by weight, preferably 20 to 75% by weight and more preferably 25 to 55% by weight of the cleaning and conditioning component.

Supplementary additives

The compositions which are added to or impregnated into the articles of the present invention may contain various optional ingredients. Some of these ingredients are detailed herein. Particularly useful are the added polymers (different from the polymeric substances that may form the substrate), various active ingredients, and cationic surfactants suitable for imparting various non-conditioning or non-cleaning benefits during skin and hair cleansing and conditioning.

Polymers

The articles of the present invention may comprise one or more polymers, preferably cationic polymers, non-ionic polymers and mixtures thereof, and more preferably cationic polymers. These cationic polymers are preferably water dispersible. The term "water-dispersible" as used herein means that the cationic polymer is dispersible either when the articles described herein are wetted and agitated to form a foam, or when the water-insoluble substrate is affected by a precomplex coacervate phase which may be added to or impregnated into the substrate independently or in combination with either a foaming surfactant or in combination with a water-soluble modifying agent. Complex cationic polymer coacervates may be formed by anionic surfactants of the article or anionic polymers, which may optionally be added to such articles (eg, polystyrene sodium sulfonate). Complex coacervates are believed to more easily deposit water-soluble conditioning agents on the skin or hair. Thus, it is generally preferred that the cationic polymer exist in / on the products of the present invention as a complexed coacervate phase, or form a coacervate phase upon dilution of the foam formed upon wetting and agitation of these products. If frf fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr fr

As the cationic polymer no longer forms a coacervate in or on the products of the present invention, the polymer will preferably exist in a complex coacervate formed at dilution.

Coacervate formation is dependent on various criteria, such as relative molecular weight, concentration and ratio of interacting ionic species, ionic strength (including ionic strength modification eg by addition of salts), charge density of cationic and anionic particles, pH and temperature. Coacervate systems and the effect of these parameters have been studied before. See. e.g., J. Caelles et al., "Anionic and Cationic Compounds in the Mixed System", Cosmetics Toiletries, Volume 106, April 1991, pp. 49-54; Van Oss, &quot; Coacervation, Complex-Coacervation and Flocculation &quot;, J. Dispersion Science and Technology, Vol. 9 (5,6), 1988-89, pp. 561-573; Burgess, D. J., &quot; Practical Analysis of Complex Coacervate Systems &quot;, J. of Colloid and Interface Science, Volume 140, No. 1, November 1990, pp. 227-238; and U.S. Pat. U.S. Patent No. 5,716,920 to Glenn Jr. et al., issued Feb. 10, 1998.

Techniques for analyzing the formation of complex coacervates are known in the art. For example, microscopic analyzes of foam at any selected dilution stage can be used to identify whether a coacervate phase is formed. This coacervate phase can be identified as another emulsified phase and dyes can be useful to distinguish the coacervate phase from other insoluble phases dispersed in the foam.

Non-limiting examples of cationic and non-ionic polymers useful herein include, but are not limited to, vegetable gums, hydrophilic colloids, biological polymers and proteins, and mixtures thereof. Suitable examples of such materials include carboxymethylhydroxyethylcellulose, carboxymethylhydroxypropylguar, carrageenan, cellulose resin, gelatin, guar gum, guarhydroxypropyltrimonium chloride, hydroxyethylcellulose, hydroxypropylmethylcellulose, hydroxypropylmethylcellulose, protein cellulose, china, china, china, , hydrolyzed cocoylkeratin, hydroxypropyltrimonium gelatin and mixtures thereof.

Cellulose-derived polymers are also useful in the present invention. By cellulose-derived polymers, as used herein, is meant those polymers that contain a cellulosic backbone, i.e., a polysaccharide backbone of repeating glucose units. In these cellulose-derived polymers, the hydroxy groups of the cellulose polymer are hydroxyalkylated (preferably hydroxyethylated or hydroxypropyllated) to form hydroxyalkylated cellulose, which is then further modified with a cationic quaternary ammonium or a protonated ammonium group. Preferred cationic modifying groups are those having at least one C ₁₀ -C ₂ alkyl chain and two shorter alkyl chains (i.e., C 1 or C 2). ₂ ) on nitrogen. Thus, the substituent on the cellulosic polymer can be depicted as - (X) NRR'R ', where X is a hydroxyalkyl group (preferably -OCH 2 CH 2 - or -OCH 2 CHOHCH 2 -), R and R' are methyl or ethyl groups and R "is C 10 - C20 alkyl group [preferably lauryl, stearyl or cocoyl (i.e. a mixture of alkyl groups derived from coconut oil)]. In other alternative structures, it has been found that when R, R 'and R "are all methyl groups (ie trimethylammonium), suitable cellulose polymers are also obtained. In yet other alternative structures, the cationic substituent on the cellulose polymer contains both hydroxy ethyl and hydroxypropyl such that such moiety can be depicted as - (OCH ₂ CH ₂ O ₎ -CH ₂ CHOHCH ₂ NRR'R ", where R, R 'and R" are methyl or ethyl and R "is a C 10 -C 20 alkyl group [preferably lauryl, stearyl or cocoyl (ie a mixture of alkyl groups derived from coconut oil)] or alternatively R, R 'and R" are all methyl groups (ie trimethylammonium).

Production methods

The disposable cleansing and conditioning products of the present invention are manufactured by separately or simultaneously applying or impregnating a foaming surfactant and conditioning ingredients to or into a water-insoluble substrate having at least one wet extensible portion, wherein the resulting product is thoroughly dry. By "separate" is meant that the surfactants and conditioning agents may be added sequentially, in any order, without being premixed. By "concurrent" is meant that surfactants and conditioning agents may be added at the same time as they may or may not be premixed. The foaming surfactant and / or conditioning component may also be added to or impregnated into one of two layers (100 or 200) in any order. Optionally, the foaming surfactant and / or conditioning component may be added to or impregnated into the resulting combination of first layer 100 and second layer 200. Treatment with the foaming surfactant and / or conditioning component may be performed at any time before or after joining the first layer 100 and the second layer. Regardless of the order of treatment, excess surfactant and / or conditioning component should be removed (e.g., by compression). The treated material (e.g., first layer 100, second layer 200, both layers 100 and 200, or bonded substrate) should then be dried by conventional methods.

For example, the second layer may be treated with a foaming surfactant prior to bonding the first layer 100 and the second layer 200. After the two layers have been joined, one of the two outer surfaces (eg, unconnected surfaces) of the layers 100 and / or 200 may be treated with a conditioning component. The foaming surfactants and conditioning agents may optionally be added to or impregnated into the second layer 200 simultaneously prior to the combination of the two layers. The foaming surfactants and conditioning agents may optionally be blended prior to addition to or impregnation into the second layer 200.

• · · · · · · · · · · · · · · · · · · · ·

Alternatively, before the two layers are joined, the first layer 100 may be treated with a foaming surfactant using methods that do not cause the first layer to be extended or expanded. This can be achieved in the production of the first layer by various application methods known to those skilled in the art. Non-limiting examples of application methods include extrusion coating and groove coating.

The surfactant, conditioning agents and any other additives may be added to or impregnated into one of two layers (100 or 200) or the resulting bonded layers (100 and 200) by methods known to those skilled in the art, eg spraying, laser printing, spraying, dipping , soaking or painting.

When water or moisture is used in the manufacturing process, or when water or moisture is present, the resulting treated substrate is dried to thoroughly dewater it. The treated substrate may be dried by any method known to those skilled in the art. Non-limiting examples of known drying methods include the use of convection ovens, radiant heat sources, microwave ovens, forced-air ovens, and heated rollers or drums. Drying also includes air drying without the addition of thermal energy other than ambient. A combination of different drying methods may also be used.

The products of the present invention, upon wetting, are capable of producing a mean foam volume of preferably equal to or greater than 30 ml, more preferably equal to or greater than 50 ml, even more preferably equal to or greater than 75 ml and most preferably equal to or greater than 150 ml.

Methods of cleansing and conditioning the skin or hair

The present invention also relates to a method of cleansing and conditioning the skin or hair with the personal cleansing product of the present invention. The methods include the steps of: wetting a thoroughly dry, disposable personal cleansing product comprising a water-insoluble substrate, a foaming surfactant, and a conditioning component, and contacting the skin or hair with the wetted product. In other embodiments, the present invention is also useful in delivering various active ingredients to the skin or hair.

The products of the present invention are thoroughly dry before use and are intended to be wetted with water before use. This product is moistened by immersion in or placing it under a stream of water. Foam is formed on the article by mechanical back and forth movements and / or deformation of the article either before or during contact of the article with skin or hair. Upon wetting, the articles of the present invention produce a mean foam volume preferably equal to or greater than 30 ml, more preferably equal to or greater than 50 ml, even more preferably equal to or greater than 75 ml, and most preferably equal to or greater than 75 ml. · Equal to or greater than 150 ml. The resulting foam is suitable for cleansing and conditioning the skin or hair. During the cleaning procedure and subsequent rinsing with water, the conditioning agents and active ingredients are deposited on the skin or hair. Deposition of conditioning agents and active ingredients is enhanced by physical contact of the substrate with the skin or hair.

A method of consistently depositing conditioning agents and any active ingredients on the skin or hair

The products of the present invention are suitable for consistently depositing the conditioning agents of the present invention on the skin or hair. In other embodiments where the active ingredient is present, the compositions are also suitable for consistently depositing the active ingredients on the skin or hair.

The products of the present invention have a depositing consistency of greater than 60%, preferably greater than 65%, more preferably greater than 70% and most preferably greater than 75%.

A measure of the consistency of depositing is the quotient obtained by dividing the depositing of the conditioning agents via "non-ideal foaming and use" by depositing the conditioning agents via "ideal foaming and use". Non-ideal foaming as used herein means that foaming is achieved by rubbing the surface of the conditioning agent product against or against each other and then contacting the skin or hair with the same surface. This causes ineffective deposition of the conditioning agents since some of the conditioning agents are emulsified by the surfactant. Ideal foaming as used herein means that foaming is achieved by rubbing the surface of the surfactant-containing article against or against each other and then contacting the skin or hair with the surface containing the conditioning component. The same starting points would be applied when both surfaces of the substrate were treated with conditioning agents (eg, deposition obtained by foaming and contacting the skin with the same foamed surface containing emulsified conditioning agents versus skin contact with a foamed surface containing unemulsified conditioning agents). Deposition consistency is maximized when the lipid hardness of the conditioning components is greater than 0.02 kg.

Quantification of the conditioning components deposited on the skin or hair can be measured using various standard analytical techniques well known to those skilled in the art. These methods include, for example, extraction of the skin or hair area with a suitable solvent and subsequent chromatographic analysis (ie, gas chromatography, liquid chromatography, supercritical fluid chromatography, etc.), IR spectroscopy, UV / VIS spectroscopy, mass spectroscopy, etc. skin or hair by techniques, • 0 0 · 0 0

0 * · * · · · · · · · · · · · · · · ·

Such as IR spectroscopy, UV / VIS spectroscopy, opacity measurement, fluorescence spectroscopy, ESCA spectroscopy and the like.

In a typical deposition measurement method, the article of the present invention is moistened with water and squeezed and moved back and forth to form a foam. The product is then rubbed for about 15 seconds with a space on the skin or head approximately 25 to 300 cm ² , preferably 50 to 100 cm ² , which is delimited by a suitable indelible marker. The site is then rinsed for 10 seconds and then allowed to air dry for 10 minutes. This site is then either extracted and the extracts analyzed or analyzed directly using any of the techniques mentioned above.
