MXPA98009055A - Cleaning articles that include a polarofobic region and an invested emulsion of elevated phase inte - Google Patents

Abstract

Cleaning tissues similar to wet handkerchiefs and similar articles that are particularly useful in the removal of perianal soiling. These tissues (201) comprise a carrier comprising at least one polarophobic region, a preferred, optional substrate (202) such as paper mesh, or continuous paper, and an emulsion (209) applied to the porator. The emulsion comprises a lipid phase, external, continuous a polar phase, internal, dispersed. The continuous, lipid phase of the emulsion is sufficiently brittle that it breaks when subjected to low cut pressures during use to release the dispersed internal phase. The inclusion of the polar phobic region allows the ability to control the flow of components of the water phase, internal after the break of the emulsion.

Description

CLEANING ARTICLES THAT INCLUDE A POLAROPHÓBIC REGION AND A HIGH INTERNAL PHASE INVERTED EMULSION CROSS REFERENCE TO RELATED APPLICATION This application is a continuation application in part of copending US Patent Application Serial No. 08 / 640,049, filed April 30, 1996 by G. Gordon et al.

TECHNICAL FIELD This application refers to items that are useful as cleaning tissues similar to wet ones. The application relates in particular to cleaning tissues similar to the wet ones made from a carrier treated with an inverted emulsion of high internal phase comprising a polar internal phase. The carrier contains a region that inhibits the penetration of polar phase components that adversely affects its concentration and integrity in use, and / or preferentially forces the polar phase to a surface of the tissue in order to maintain a second, dry surface . Handkerchiefs are useful in various applications, including those for cleaning hard surfaces and for personal cleansing such as baby handkerchiefs, and particularly for the removal of anal dirt.

BACKGROUND OF THE INVENTION The cleaning of the skin is a problem of personal hygiene that is not easily solved. Of course, the common procedure for washing the skin with soap and water works well, but sometimes it may not be available or inconvenient to use. While soap and water can be used to clean the perianal region after defecation, for example, this procedure would be extremely heavy. Dry paper products are therefore the most commonly used post-defecation anal cleansing product. These dry paper products are usually referred to as "toilet paper" or "sanitary paper". Perianal skin is marked by the presence of fine folds and wrinkles (furrows) and hair follicles that make the perianal region one of the most difficult anatomical areas of cleansing. During defecation, stool is excreted through the anus and tends to accumulate hard to reach locations such as around the base of the hair and in the grooves on the surface of the skin. As fecal matter is dehydrated on exposure to air, or in contact with an absorbent cleaning implement such as toilet paper, it adheres more tenaciously to the skin and hair, making difficult the subsequent removal of dehydrated, remaining dirt. Failure to remove fecal matter from the anal area can have a detrimental effect on personal hygiene. The stool that remains on the skin after post-defecation cleansing has a high bacterial and viral content, is malodorous and dehydrates in general. These characteristics increase the likelihood of perianal disorders and cause personal discomfort (eg, itching, irritation, etc.). In addition, residual fecal matter stains undergarments and causes unpleasant odors emanating from the anal region. In this way, the consequences of inadequate perianal cleansing are clearly unnoticed. For those individuals suffering from anal disorders such as pruritus, hemorrhoids, fissures, cryptitis, or the like, the importance of adequate perianal cleansing takes on a highlighted meaning. Perianal disorders are usually characterized by openings in the skin through which bacteria and viruses can easily enter the residual fecal matter. Those afflicted with anal disorders should therefore achieve a high degree of perianal cleansing after defecation or risk will remain on the skin with the result that their disorders will P710 aggravated by bacteria and viruses. At the same time, victims of anal disorders face more severe consequences of insufficient post-defecation cleansing, since they have greater difficulty in achieving a satisfactory level of dirt removal. The anal disorders return in general to the extremely sensitive perianal region and attempts to remove fecal matter from this region by rinsing with normal rinsing pressure causes pain and can further irritate the skin. Attempts to prevent the removal of dirt by increasing the rinsing pressure can result in severe pain. Contrary, attempts to minimize discomfort by reducing the rinsing pressure give an increased amount of residual fecal material left on the skin. The conventional toilet paper products used for anal cleansing are essentially dry, low density papers that rely exclusively on mechanical processes to remove fecal material from the perianal skin. These conventional products are rubbed against the perianal skin, typically with a pressure of about 7 kilopascals (1 psi) and basically scrape or scour the fecal material from the skin. After the first cleanings, the upper portion of the dirt layer is removed because the rinsing process is P710 able to overcome the cohesive forces dirt in dirt that exist within the fecal matter. A split in the dirt layer itself is thus created to the upper portion of the faecal layer that is removed in the lower portion of the dirt that remains adhered to the perianal skin. The conventional paper products are absorbent and with each successive cleaning, the fecal material becomes increasingly dehydrated, making it stick more tenaciously to the perianal skin and making its removal extremely difficult. Pressing the paper forcefully against the perianal skin will further remove the fecal matter but is intensely painful for people suffering from perianal disorders and may even skip normal perianal skin, potentially causing irritation, inflammation, pain, bleeding and infection. To improve perianal cleaning, tissues have been developed that are kept in a dispenser and soaked in a reservoir of a moisturizing solution. Examples of these products include handkerchiefs that are frequently used to clean babies after bowel movements and may have other additives in the moisturizing solution to mitigate the skin. These handkerchiefs may have a permanent wet concentration, such that they are not copious. Also, these P710 Previous tissues are often damp to dry the skin and tend to have a "cold" feel. There is also a lack of consistency in terms of the moisture content of each of the tissues. Wettable dry paper products have also been used in perianal cleaning. These wettable paper products usually have a temporary wet concentration such that they are copious. However, the users of these products have to wet the paper separately, which can be inconvenient. It is also difficult to obtain the desired level of moisture with these products. Also, the temporary wet concentration of these products is typically inadequate and needs to be improved. The North American Patent Application No. 08 / 336,456, Copendiente, filed on November 9, 1994, by L. Mackey et al., Describes and claims wet cleaning handkerchiefs that are especially useful in the removal of perianal soiling. These cleaning tissues comprise a substrate material (for example, non-woven) which is treated with a water-in-lipid emulsion. These handkerchiefs have a number of significant advantages over the above cleaning products, especially when they are in the form of wet-like cleaning handkerchiefs used for removal of perianal dirt. These items release significant amounts of water during use for the most effective, comfortable cleaning. The continuous lipid phase of the emulsion is sufficiently brittle to be easily broken by contact with little cut (for example, during rinsing of the skin) to easily release this internal phase of water, but sufficiently hard at elevated temperatures where it melts the lipid to prevent the premature release of the water phase during the rigors of the procedure. The continuous lipid phase of these articles is also sufficiently stable during storage to prevent significant evaporation of the internal water phase. The normal tensile and floatability properties, those articles are not adversely affected when treated with high internal phase inverted emulsions of the present invention. As a result, users of these items get a damp, efficient, comfortable cleaning, which tends to change their normal cleaning habits. Despite significant improvements over the above cleaning tissues, the substrates (also referred to as "carriers") described herein are lacking in one aspect. Specifically, because the described carriers are hydrophilic materials, in cutting the emulsion in use, a significant amount of water is absorbed into the substrate, therefore it is not available for contact with the article to be cleaned. As such, it is necessary to surface treat the substrate with additional amounts of emulsion to account for the level of water absorbed by the carrier. Accordingly, in certain circumstances, it would be desirable to provide cleaning products that offer the benefits provided by the cleaning tissues described in the above Copending application, but which require treatment with reduced levels of emulsion. This will provide, among other things, simplification of the handkerchief process, as well as potential economic advantages since less emulsion will be required to offer the desired wetting effects.

SUMMARY OF THE INVENTION The present invention relates to articles useful in cleaning, and particularly wet-like cleaning handkerchiefs which are especially useful in the removal of perianal soils. These items include: a. a carrier comprising a region polarophobic and optionally, one or more layers of polarophilic substrate; and b. an emulsion applied to the carrier, the emulsion comprising: (1) from about 2 to about 60% of a solidified, continuous internal lipid phase comprising a waxy lipid material having a melting point of about 30 ° C or higher; (2) about 39 to about 97% of an internal polar phase dispersed in the external lipid phase; and (3) an effective amount of an emulsifier capable of forming the emulsion when the external lipid phase is in a fluid state. The present invention also relates to a method for making these articles. This method comprises the steps of: A. Form an emulsion comprising: (1) from about 2 to about 60% of the continuous, external lipid phase, comprising a lipid, waxy material, having a melting point of approximately 302C or higher; (2) from about 39 to about 97% of an internal polar phase dispersed in the lipid phase, external; Y (3) an effective amount of an emulsifier capable of forming the emulsion when the external lipid phase is in a fluid state; b. applying the emulsion to an applicator at a sufficiently high temperature such that the external lipid phase has a plastic fluid consistency, the carrier containing a polarophobic region, and optionally, one or more layers of polarophilic substrates; and c. employ the emulsion applied at a sufficiently low temperature such that the external lipid phase solidifies. The articles of the present invention offer a number of significant advantages or over the above cleaning products, especially when they are in the form of wet-like cleaning tissues used to remove perianal soils. These articles release significant amounts of internal polar phase components (e.g., preferably, water or aqueous solutions) during use for comfortable, more effective cleaning. The lipid phase, continuous with the emulsion is sufficiently brittle to be easily broken by the low-cut contact (eg, during rinsing of the skin) to easily release this internal phase, but hard enough to prevent premature release of the internal polar phase during the P710 rigors of the procedure. The continuous lipid phase of these articles is also stable enough during storage to prevent significant evaporation of the internal polar phase. The properties of the attraction and floatability resistance, normal, these articles are not adversely affected when treated with the high internal phase inverted emulsions of the present invention. As a result, users of these items get a comfortable clean, efficient, moist, without having to change the normal cleaning habits. Because the carriers used in the articles of the present invention comprise a polarophobic region, the relative amount of the polar phase components available on the surface (s) of the article after rinsing is increased. This achieves by placing the polar phobic region such that the internal phase material released in the cut is not absorbed throughout the thickness, width and / or length of the article, but rather directs desired portions thereof. In one aspect, the polar phobic region of the carrier allows the use of an emulsion technology in high density polarophilic carriers by retaining the polar phase released on the surface of the article. In a preferred embodiment, the porlarphobic region is a discrete layer located in the carrier such that one side of the article will wet under the cut, while on the other side it will remain dry for a secondary drying step. That is, in this mode, the internal polar phase does not penetrate the full thickness of the carrier. In addition to perianal cleaning, these articles can be used in many other applications that require the distribution of polar fluids such as water, as well as active products that are soluble or dispersible in polar fluids. These include handkerchiefs for personal cleansing, such as baby handkerchiefs; for cleaning hard surfaces of floors, against ceilings, sinks, bathtubs, toilets and the like; as well as those for the distribution of active microbial or pharmaceutical products, soluble or dispersible in polar solvents. These articles can also play multiple functions. For example, the internal phase invert emulsion applied to these articles can be formulated to provide cleaning and waxing benefits at the same time when used in articles such as furniture, shoes, automobiles and the like.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic representation illustrating a spray system for applying the high internal phase inverted emulsions of the present invention P710 to a carrier substrate such as a continuous paper. Figure 2 is a schematic representation illustrating a system for applying the high internal phase inverted emulsions of the present invention by flexible rotogravure coating to a carrier substrate such as continuous paper. Figure 3 is a cross-sectional view of an article of the present invention where the internal phase comprises a significant level of water. This embodiment, article 201 comprises a hydrophilic sheet 202 treated on one of its surfaces with a hydrophobic material to form hydrophobic layer 205, and treated on the other surface with a hydrophobic material to test hydrophobic layer 206. A first layer 209 of emulsion is located in the hydrophobic layer 205, and a second emulsion layer 210 is located a hydrophobic layer 206. In the embodiment, the hydrophobic layers 205 and 206 are continuous, they are formed by treating both sides of the sheet 202 with 5% p / p of the Syloff 7677 and Syloff 7048 crosslinker in a weight ratio of 95/5, available from Dow Corning Corp., Midland, MI. Figure 4 is a cross-sectional view of another article of the present invention where the internal phase comprises a significant level of water. The Article 301 comprises a hydrophobic layer 305 is a P710 Film formed of polyethylene or polypropylene. A hydrophobic layer surface 305 is treated with emulsion 309. The other side of layer 305 is attached to hydrophilic substrate 303. A second hydrophilic substrate 302 is located in emulsion layer 309. In this embodiment, the pressure in use causes the emulsion 309 to break, causing thereby releasing the components of the internal water phase, which are allowed to penetrate through the hydrophilic layer 302 to a surface of the article. The hydrophobic layer 305 prevents the components of the water phase from penetrating the hydrophilic layer 303. The layer 303 therefore remains dry and can be used to obtain the water components after rinsing. Figure 5 is a cross-sectional view of the article of the present invention where the internal phase comprises a significant level of water. The article 401 comprises a hydrophobic layer 405 which is a film formed of polyethylene or polypropylene. A surface of hydrophobic layer 405 is attached to a first substrate 402 of hydrophilic paper. One layer 409 is applied to the hydrophilic substrate 402. The other surface of the hydrophobic layer 405 is attached to a second hydrophilic substrate paper 403. The other layer 410 is applied to the hydrophilic substrate 403. FIG. 6 is a cross-sectional view of the substrate. another article of the present invention where the phase P710 internal comprises a significant level of water. In this modality, the article 501 is represented as comprising a hydrophobic layer 505 and is a film filmed from polyethylene or polypropylene. One surface of layer 505 is attached to sanitary (hydrophilic) paper 503. The other surface of layer 505 is coated with an emulsion layer 509. A second emulsion layer 509 is coated on a second (hydrophilic) sanitary paper 502. The hydrophilic toilet paper 502 is attached to the surface treated with the emulsion of the hydrophobic layer 505, such that two emulsion layers 509 are located between the toilet paper 502 and the layer 505. This provides a result similar to that exhibited in the article. 301 of Figure 4, but with additional emulsion that is present because they are treated with two surfaces.

DETAILED DESCRIPTION As used herein, the term "comprising" means that the various components, ingredients, or steps, may be employed together in the practice of the present invention. Accordingly, the term "comprising" embraces the more restrictive terms "consisting essentially of" and "consisting of". As used herein, the terms P710"Detergent", "Detersive Surfactant" and "Detergent Surfactant" are used interchangeably, and refer to any substance that reduces the stress of water, specifically an active agent on the surface that concentrates in the oil slicks. water, exert emulsion action, and in this way help in the removal of dirt. As used herein, the term "polar" means a molecule that possesses a bipole moment, that is, a molecule from which the positive and negative electric charges are permanently separated, as opposed to a non-polar molecule in the which charges coincide. A "polar fluid" may comprise one or more polar substituents. As used herein, the term "Polarphilic" is used to refer to surfaces that are wettable by polar fluids deposited therein. Polarophilicity and wettability are typically defined in terms of contact and the surface tension of the fluids and the solid surfaces involved. This is discussed in detail in the American Chemical Society's publication Contact Angle, Wettability and Adhesion, edited by Robert F. Gould (Copyright 1964), which is hereby incorporated by reference. A surface that is going to be wetted by a fluid in the P710 say, polarophilic) when either the contact angle between the polar fluid and the surface is less than 90s, or when the polar fluid tends to spontaneously spread across the surface, both conditions coexisting normally. Conversely, a surface that is "polarophobic" is considered if the contact angle is greater than 902 and the fluid does not spontaneously spread across the surface. Since water is in general the preferred polar material used in the present invention, the preferred embodiments chosen herein refer to the "hydrophilicity" and "hydrophobicity" of the substrate. However, the use of these terms is not limited and must be read to include "polarophilic" and "polarophobic" substrates. In addition, the description of a carrier as having polarophobic (hypolarophilic) choices necessarily refers to the internal polar phase that is used in the emulsion. As used herein, the term "hydrophilic" is used to refer to its surfaces that are wettable by aqueous fluids deposited therein. Hydrophilicity and wettability are typically defined in terms of the contact angle and surface tension of the fluids and the solid surfaces involved. This is discussed in detail in the American Chemical Society's publication Contact Angle, P710 Wettability and Adhesion, edited by Robert F. Gould (Copyright 1964), which is incorporated in this way by reference herein. A surface that is to be wetted by a fluid (i.e., hydrophilic) when either the contact angle between the fluid and the surface is less than 902, or when the fluid tends to spontaneously spread across the surface, both conditions They coexist normally. Conversely, a surface that is "hydrophobic" is considered if the contact angle is greater than 902 and the fluid does not spontaneously extend across the surface. As used herein, the terms "substrate" and "layer", when used to describe the carriers of the present invention, refer to a component whose primary dimension is XY, i.e., along its length and width . It should be understood that the terms substrate and layers are not necessarily limited to individual substrates / layers, or sheets of material. In this way, a substrate or layer can comprise products laminated in combinations of several sheets or continuous papers of the required type of materials. Accordingly, the term "substrate" includes "substrates", and the term "layer" includes the terms "layers" and "layers." All percentages, ratios and proportions used herein are by weight unless P710 Specify otherwise.

A. Carrier for High Internal Phase Inverted Emulsion The carriers of the present invention will comprise at least one polarophobic region and preferably at least one layer of polarophilic substrate. These materials are described in greater detail below, when described in terms of their hydrophobicity and hydrophilicity. It is understood that where an emulsion having a polar internal phase comprising significant levels of preferred water material (s), the terms "polarophobic" and "polarophilic", respectively, are proposed. 1. Hydrophobic Region The hydrophobic region (s) of the carrier can be generated either by 1) treating a hydrophilic substrate (described below) with a water-repellent compound (s) or 2) using a hydrophobic material, such as a thin hydrophobic film or a layer of hydrophobic fibers, as a distinct layer. The preferred design of these products will be a durable hydrophobic region that does not adversely affect the feel or softness of the wearer. When the hydrophobic region is formed via P710 surface treatment of a hydrophilic treatment, the hydrophobic material is applied to the substrate by traditional spray, coating and printing techniques, then cured through heat sources and / or ultraviolet light. (Surface treatment with hydrophobic materials is described, for example, in co-pending US Patent Application Serial No. 08 / 442,935, filed May 31, 1995 by W. Ouellette et al. Entitled "Fluid Transport Webs Exhibiting" Surface Energy Gradients "(Case 5337R2), which is incorporated herein by reference). The resulting carrier is a substrate with at least one surface having at least one hydrophobic region. One skilled in the art will recognize that the application of the hydrophobic material can be controlled such that numerous discrete, discontinuous, hydrophobic regions are provided on the surface of the substrate, or the entire surface of the substrate can be treated to provide a continuous hydrophobic layer. Numerous hydrophobic materials capable of being deposited on a substrate such as a nonwoven are known in the art and are useful herein. Preferred examples include a silicone material from Dow Corning of Midland, Michigan, available as Syl-Off 7677 to which a crosslinker available as Syl-Off 7048 is added in weight proportions of 100 parts to 10 parts, P710 respectively. Another suitable surface treatment is a coating of a UV curable silicone comprising a blend of two silicones commercially available from General Electric Company, Silicone Products Division, of Waterford, NY. , under the designations UV 9300 and UV 9380C-D1, in proportions by weight of 100 parts to 2.5 parts, respectively. Other suitable materials include, but are not limited to, fluorinated materials, such as fluoropolymers (e.g., polytetrafluoroethylene (PTFE), commercially available under the trademark TEFLON) and chlorofluoropolymers. Other materials that can prove to be suitable, such as hydrophobic material are petrolatum, latex, paraffins and the like, although silicone materials are concerned. Others include any of the commercial water repellents cited in Volume 2 of McCutcheon's: Functional Materials 1995, McCutcheon's Division. The Manufacturing Confectioner Publishing Co. (the description of which is incorporated by reference herein) of which GrapHsize, available from Akzo Nobel Chemicals Inc., and Norgard 10-T, available from Norman Fox & Co., are preferred. The necessary addition levels of the hydrophobic compound will depend on the substrate, but will generally fall in the range from about 1% to about 10% addition based on the dry weight of the substrate layer.

P710 The incorporation of a thin film or fiber layer to provide the hydrophobic region of the carrier can be achieved by using any type of resin that can be extruded to form a hydrophobic film or fiber layer. Resins useful in the formation of hydrophobic films / fibers include, but are not limited to polyolefins such as polyethylene or polypropylene, polyacrylics, polyamides, polystyrenes, polyurethanes and the like. Thin films derived from polyolefins, preferably polyethylene or polypropylene, are most preferred. The film or fibers can be used as a hydrophobic flat sheet layer and can optionally be attached to an average adhesive substrate, temperature bonding, or pressure bonding. Due to the need for flexibility of the tissue article to allow for better cleaning, it is desirable to mechanically treat the hydrophobic thin films in such a way as to make it more flexible. The ring winding is an action that gives the film more flexibility. This technique is described in greater detail in U.S. Patents Nos. 5,164,897 to Weber et al., And No. 5,366,782 to Curro et al., Both of which are incorporated herein by reference. An alternative means to achieve flexibility is to use a continuous paper of P710 films similar to an elastic, structural, hydrophobic (referred to later as "SELF"). A continuous paper of elastic-like film, structural, is an extendable material that exhibits a behavior similar to an elastic in the direction of elongation without the use of additional elastic materials. The SELF continuous papers and the techniques for obtaining the "SELF" films are described in commonly assigned, copending, inclined US Patent Application Serial No. 08 / 203,456"Absorbent Article with Multiple Zone Structural Elastic-Like Film Web Extensible Waist feature ", presented by D. Roe, and collaborators on February 24, 1994, which is incorporated herein by reference. In addition, a micro-aperture film allows flexibility while maintaining a hydrophobic barrier against moderate pressure. Preferred articles are those in which the hydrophobic region is either a cross-linked silicone compound or applied to all or a portion (preferably all) of one or both surfaces (preferably one) of the hydrophilic substrate (s) or a thin, mechanically treated polymer film, such as polyethylene treated with ring roller or SELF.

P710 2. Hydrophilic Substrate Layer The carriers of the present invention preferably comprise at least one hydrophilic substrate layer. Suitable materials for use as the substrate include woven materials, non-woven materials, foams, sponges, wadding, beads, bedspreads, films, and the like. Particularly preferred substrates for use in the present invention are the non-woven types. These nonwoven substrates may comprise any conventionally formed nonwoven sheet or mesh having a suitable basis weight, gauge (thickness), absorbency characteristics and strength. Non-preferred substrates can be defined in general as fibrous or filamentary, bonded products having a mesh structure, in which the fibers or filaments are randomly distributed as in "settling in the air" processes or certain "settling" processes wet "or with a degree of orientation, as in certain processes of" wet settlement "or" loaded ". The fibers and filaments of these non-woven substrates can be natural (for example, wood pulp, wool, silk, jute, hemp, cotton, linen, enequen, or ramia) or synthetic (for example, polyvinyl derivatives, cellulose ester , rayon, polyolefins, polyamides or polyesters) and can be joined together with a resin of P710 polymeric binder. Examples of commercially available, suitable nonwoven substrates include those sold under the trademark Sontara "by DuPont and Polyweb® by James River Corp. For reasons of cost, ease of manufacture and availability of the article (eg, floodability), the Preferred type of the nonwoven substrate used in handkerchiefs of the present invention comprises those made of wood pulp fibers, for example, continuous papers As noted, the continuous papers can be separated by techniques of either air sedimentation or sedimentation in The continuous papers sedimented in air such as Air Tex® SC130 are commercially available from James River Corp. More conventionally, the continuous papers are made by wet sedimentation procedures, in these processes, a continuous mesh or paper is made to form an aqueous papermaking finish, depositing this finish on a super It is a formalin material, such as the Fourdrinier wire, and then removes the water when draining, for example, by gravity, by drying aided by vacuum and / or by evaporation, with or without pressing, to thereby form a paper mesh of fiber silk consistency. In many cases, the papermaking apparatus is adjusted to rearrange P710 the fibers in the slurry of the finished papermaking as the dehydration continues to form paper-length substrates, handling, volume, appearance, absorbency, especially desirable, etc. The papermaking finish used to form the preferred paper mesh substrates for articles of the present invention essentially comprises an aqueous suspension of papermaking fibers (i.e., paper pulp) and may optionally contain a wide variety of products. Chemicals such as wet strength resins, such surfactants, pH control agents, softness additives, debonding agents and the like. The wood pulp in all its variations can be used to form the finished papermaking. The wood pulps useful herein include both sulphite and sulfate pulps, as well as mechanical, thermomechanical and chemo-thermo-mechanical pulps, all of which are well known to those skilled in the papermaking art. Pulps derived from deciduous or coniferous trees can be used. Preferably, the papermaking end for forming the preferred paper mesh substrates for handkerchiefs of the present invention comprises the Kraft pulp derived from the P710 from soft northern woods. A manufacturing number of paper processes have been developed which utilize a papermaking apparatus that forms paper meshes having desirable or particularly useful fiber configuration. These configurations can serve to impart these characteristics of the paper mesh as improved volume, absorbency and strength. One such process employs a printing fabric in the papermaking process which serves to impart a knuckle pattern of high density and low density areas in the resulting paper mesh. A process of this type, and the papermaking apparatus for carrying out this process, is described in greater detail in U.S. Patent No. 3,301,746 (Sanford et al.), Issued January 31, 1967, which is incorporated herein by reference. the present by reference. Another papermaking process employs a step drying fabric having relief knuckles raised above the plane of the fabric. These impressions create protrusions on the dried sheet of passage, and provide the sheet with elasticity in the direction through the machine. A process of this type is described in European Patent Publication No. 677,612A2, published on October 18, 1995 by G. Wendt et al., The description of which is described herein by reference.

P710 Yet another papermaking process carried out with a special papermaking apparatus is one that provides a paper mesh having a different, continuous network region formed by a plurality of "dome" dispersed to everything length of the network region in the substrate. These domes are formed by compressing an embryonic mesh as formed during the papermaking process in a foraminous deflection medium having a pattern network surface formed by a plurality of discrete, isolated, deflection conduits on the surface of the web. diversion member. A process of this type, and the apparatus for carrying out the process is described in greater detail in U.S. Patent No. 4,529,480 (Trokhan), issued July 16, 1985; U.S. Patent No. 4,637,859 (Trokhan), issued January 20, 1987; and U.S. Patent No. 5,073,235 (Trokhan), issued December 17, 1991, all of which are incorporated by reference. Another type of process in papermaking and the apparatus for carrying out that is suitable for manufacturing composite paper substrate, in layers, is described in US Patent No. 3,994,771 (Morgan et al.); issued on April 30, 1976, which is incorporated herein by reference. Preferred paper mesh substrates should P710 form one of two or more folds that can be laminated together. The lamination, and the lamination carried out in combination with an embossing process to form a plurality of protrusions in the laminated product, is described in greater detail in U.S. Patent No. 3,414,459 (Wells); issued on December 3, 1968, which is incorporated by reference. These paper substrates preferably have a basis weight between about 10 g / m2 and about 65 g / m2 and a density of about 0.6 g / cc or less. Preferably, the basis weight will be about 40 g / m2 or less and the density will be less than about 0.3 g / cc or less. Preferably, the density will be between about 0.04 g / cc and about 0.2 g / cc. See column 13, lines 61-67, from U.S. Patent No. 5,059,282 (Ampulski et al.), Issued October 22, 1991, which describes how the density of the sanitary paper is measured. (Unless otherwise specified, all amounts and weight in relation to the paper mesh or continuous paper substrate are on a dry weight basis). In addition to the papermaking fibers, the finished papermaking used to make these paper mesh substrates may have other components or materials added thereto, are or become P710 subsequently known in the art. The types of desirable additives will depend on the proposed end use of the sheet of the contemplated fabric. For example, in handkerchief products such as toilet paper, paper towels, facial paper, baby handkerchiefs and other similar products, a high wet strength is a desirable attribute. In this way, it is often desirable to add to the papermaking finishing chemicals known in the art as "wet strength" resins. A general dissertation on the types of resistance of queens not used in the paper technique can be found in the article series TAPPI No. 29, Wet Strength in Paper and Paperboard, Technical Association of the Pulp and Paper Industry (New York, 1965 ). The most useful wet strength resins have been generally cationic in nature. For the generation of permanent number strength, the polyamide-epichlorohydrin resins are cationic wet strength resins that have been found to be of particular utility. Suitable types of these resins are described in the patent North American No. 3,700,623 (Keim), issued on 24 October 1972, and US Patent No. 3,772,076 (Keim), issued on November 13, 1973, both of which are incorporated by reference. A commercial source P710 of a useful polyamide-epichlorohydrin resin is Hercules, Inc. of Wilmington, Delaware, which sells this resin under the trademark Kymene® 557H. It has also been found that polyacrylamide resins are useful as wet resins resistance. These resins are described in U.S. Patent Nos. 3,556,932 (Coscia et al.), Issued January 19, 1971, and No. 3,556,933 (Williams et al.), Issued January 19, 1971, both of which are incorporated by reference. A commercial source of polyacrylamide resins is American Cyanamid Co., of Stamford, Connecticut, which sells this resin under the trademark ParezR 631 NC. Still other cationic water-soluble resins which find utility as wet strength resins are the urea-formaldehyde and melamine-formaldehyde resins. The most common functional groups of these polyfunctional resins are nitrogen-containing groups such as amino groups and methylol groups attached to nitrogen. Polyethylene imine queens may also find utility in the present invention. In addition, the temporary wet strength resin such as Caldas 10 (manufactured by Japan Carlit), CoBond 1000 (manufactured by National Starch and Chemical Company) and Parez 750 (manufactured by American Cyanamide Co.) Can be used in the P710 present invention. It should be understood that the addition of the chemical products such as the temporary wet strength and wet strength resins discussed above with respect to pulp finishes is optional and not necessary for the practice of the present invention. In addition to wet strength additives, it may also be desirable to include certain paper control fibers and dry strength additives known in the art. In this regard, starch binders have been found to be particularly suitable. In addition to reducing the lint formation of the paper substrate, the low levels of starch binders also my part a modest improvement in dry attraction strength without imparting stiffness that could result from the addition of high levels of starch. Typically, the starch binder is included in such an amount that it is retained at a level from about 0.01 to about 2%, preferably from about 0.1 to about 1%, by weight of the paper substrate. In general, suitable starch binders for these paper mesh substrates are characterized by water solubility, hydrophilicity. Although it is not proposed to limit the range of starch binders P710 suitable, representative starch materials include corn starch, potato starch, with silky corn starch known initially as amioca starch which is particularly preferred. Amioca starch differs from common corn starch as it is completely amylopectin, whereas common corn starch contains both amylopectin and amylose. Several unique characteristics of amioca starch are further described in "Amioca - The Starch From Waxy Corn." H. H. Schopmeyer, Food Industries, December 1945, pp. 106-108 (Vol. Pp. 1476-1478). The corn binder may be in granular or dispersed form, the starch form especially preferred. The starch binder is preferably preferably sewn to induce swelling of the granules. More preferably, the starch granules swell, since when sewn, to a point just before the starch granule dispersion. These highly swollen starch granules should be referred to as "highly stitched". The conditions for expression in general may vary depending on the size of starch granules, granules of crystallinity of the granules, and the amount of the amylose present. Fully stitched amioca starch, for example, can be prepared by heating an aqueous slurry of P710 about 4% consistency of starch granules at about 19O2 F (about 882 C) for between about 30 and about 40 minutes. Other exemplary starch binders that can be used include modified cationic starches such as those modified to have nitrogen-containing groups, including amino groups, methylol groups, attached to nitrogen, available from the National Starch and Chemical Company, (Bridgewater, New Jersey ), which has previously been used as pulp finisher additives to increase wet and / or dry strength. Many of the materials described as useful as the optional hydrophilic substrate layer are inherently hydrophilic. Materials that are not naturally hydrophilic can be treated with any variety of hydrophilizing agents well known in the art. Suitable surfactants for hydrophilization include, for example, ethoxylated esters such as Pegosperse® 200-ML, manufactured by Glyco Chemical, Inc. of Greenwich, Connecticut, ATMRR 645, manufactured by ICI, glucose amides, triblock copolymers of ethylene and propylene oxide such as Pluronic® P103, manufactured by BASF, and ethylene glycol silicone copolymers such as DC190, manufactured by Dow Corning of Midland, Michigan. Surfactants can be P710 applied to the surface of the substrate by spraying, printing, or other suitable methods such as those described in US Patent No. 4,950,264, issued to Osborn on August 21, 1990, the description of which is incorporated herein by reference.

B. Internal high phase inverted emulsion The articles of the present invention comprise an emulsion that is applied to the carrier. The following describe preferred materials useful in the preparation of emulsions. It is understood that where an emulsion having a polar internal phase comprising significant levels of material (s) different from water, the terms "polarophobic" and "polarophilic", respectively, are proposed. Where an optional hydrophilic substrate layer is present, the emulsion will be applied to either the hydrophilic substrate and the hydrophobic region (s). Preferably, the emulsion is preferably applied to the hydrophilic substrate. The emulsion comprises: (1) a lipid phase, external, solidified, continuous; (2) an emulsifier that forms the emulsion when the external lipid phase is fluid; and (3) a polar phase, internal, dispersed in the lipid phase, external. Because the internal phaseP710 It contains a high level of polar material, this emulsion is typically referred to as an "inverted high internal phase emulsion". The inverted emulsion of high internal phase is broken when subjected to a low cut during use, for example, rinsing of the skin or other surface, to release the internal polar phase. 1. External Lipid Phase The outer, solidified, continuous lipid phase provides the essential stabilizing structure for the high internal phase inverted emulsions of the present invention. In particular, this continuous, lipid phase is what keeps the internal polar phase dispersed from being released prematurely before use of the article, such as during storage. The continuous, external lipid phase may comprise from about 2 to about 60% of the emulsion of the present invention. Preferably, this continuous, lipid phase will comprise from about 5 to about 30% of the emulsion. More preferably, this lipid phase will comprise from about 6 to about 15% of the emulsion. The main constituent of this lipid phase, continuous, is a lipid, silky material. That P710 Lipid material is characterized by a melting point of about 302 C or higher, i.e., it is solid at ambient temperatures. Preferably, the lipid material has a melting point of about 50 ° C or higher. Typically, the lipid material has a melting point in the range of from about 40a C to about 802 C, more typically, in the range from about 50a to about 702C. Although this silky, lipid material is solid to ambient temperatures, it also needs to be fluid in plastic at those temperatures at which the carrier is applied, the inverted emulsion of this internal phase. In addition, although the lipid material is fluid to the plastic those temperatures at which the emulsion is applied to the carrier substrate, it must still be desirable that it be somewhat stable (i.e., have a coalescence of emulsion micro-droplets) for extended periods of time. time at elevated temperatures (e.g., about 502 C or greater) that is normally encountered during storage and distribution of the articles of the present invention. This lipid material also needs to be sufficiently brittle to the conditions of use cut of the article such that it breaks and releases the internal polar phase, dispersed. These lipid materials P710 it should also desirably provide a good feeling to the skin when the personal care product is used such as wet-like cleaning tissues and paper used in perianal cleaning. Suitable lipid, silky materials for use in the high internal phase inverted emulsion of the present invention include natural and synthetic waxes, as well as other oil soluble materials having a serous consistency. As used herein, the term "wax" refers to organic mixtures or compounds that are generally insoluble in polar materials such as water and tend to resist as microcrystalline amorphous solids at room temperatures (eg, about 252 C). Suitable waxes include various types of hydrocarbons, as well as esters of certain fatty acids and fatty alcohols. These can be derived from natural sources (ie, animal, vegetable or animal) or can be synthesized. Mixtures of various waxes can also be used. Some representative animal or vegetable waxes that can be used in the present invention include beeswax, carnauba, whale sperm, lanolin, lacquer wax, candelilla, and the like. Animal and vegetable waxes, particularly preferred are beeswax, lanolin and candelilla. Representative waxes P710 and mineral sources that can be used in the present invention include petroleum-based waxes such as paraffin, microcrystalline wax petrolatum, and fossil or ground waxes such as white ceresin wax, yellow ceresin wax, white ozocerine wax, and the like. Particularly preferred mineral waxes are petrolatum, microcrystalline wax, yellow ceresin wax, and white ozocerine wax. Representative synthetic waxes that can be used in the present invention include ethylenic polymers such as polyethylene wax, chlorinated naphthalenes such as "Halowax", hydrocarbon type waxes made by the Fischer-Tropsch synthesis, and the like. Particularly preferred synthetic waxes are polyethylene waxes. In addition to the lipid material as waxy, the continuous lipid phase may include minor amounts of other lipophilic or lipid miscible materials. These other lipofilic / lipid visible materials are typically included for the purpose of stabilizing the emulsion to minimize water loss or to improve the aesthetic feel of the emulsion in the skin. Suitable materials of this type that may be present in the continuous lipid phase include hot melt adhesives such as Findley 193-336 resin, long chain alcohols such as cetyl alcohol, alcohol P710 stearyl, and cetearyl alcohol water insoluble soaps such as aluminum stearate, silicone polymers such as polydimethylsiloxanes, hydrophobically modified silicone polymers such as phenyl trimethicone, and the like. Other suitable lipophilic / miscible lipid materials include polyol polyesters. By "polyol polyester" is meant a polyol having at least 4 ester groups. By "polyol" it is necessary to say a polyhydric alcohol having at least 4, preferably from 4 to 12, and more preferably from 6 to 8, hydroxyl groups. Polyols include polysaccharides, disaccharides and trisaccharides, sugar alcohols and other sugar derivatives (e.g., alkyl glycosides), polyglycerols (e.g., diglycerol and triglycerol), pentaerythritol, and polyvinyl alcohols. Preferred polyols include xylose, arabinose, ribose, xylitol, erythritol, glucose, methyl glucoside, mannose, galactose, fructose, sorbitol, maltose, lactose, sucrose, raffinose and maltotriose. Sucrose is an especially preferred polyol. With respect to the polyol polyesters useful herein, it is necessary that all the hydroxyl groups of the polyol are esterified, however, the disaccharide polyesters can have only 3, and preferably no more than 2, non-esterified hydroxyl groups. Typically, substantially all (for example, at least 85%) of the P710 hydroxyl groups of the polyol are esterified. In the case of the sucrose polyesters, typically about 7 to 8 of the polyol hydroxyl groups are esterified. By "liquid polyol polyester" is meant a polyol polyester of the groups defined herein below having a fluid consistency at or below about 372 C. By "solid polyol polyester" is meant a polyester polyol starting from of which the groups described hereinafter have a plastic or solid consistency at or above about 372 C. As described hereinafter, the liquid polyol polyesters and the solid polyol polyesters can be used successfully as emollients and immobilization agents, respectively, in the emulsions of the present invention. In some cases, the solid polyol polyesters may also provide some emolliency functionality. 2. Internal Polar Phase Typically, the main component of the high internal phase inverted emulsions of the present invention is the internal polar phase dispersed.

This internal polar phase can provide a number of different benefits when released. For example in P710 cleaning tissues similar to wet, preferred, for perianal cleaning, this inner polar phase released (preferably water) provides the primary cleaning action for these handkerchiefs. In other products, the internal polar phase released can be used to distribute a variety of active components that are soluble or dispersible in polar lipids (preferably water). The internal polar phase can comprise from about 39 to about 97% of the emulsion of the present invention. Preferably, the internal polar phase will comprise from about 67 to about 92% of the emulsion. More preferably, the polar phase will comprise from about 82 to about 91% of the emulsion. In preferred embodiments, the internal polar phase will comprise water as the main constituent. That is, the emulsion will be an emulsion of water in lipid. In preferred embodiments, the internal polar phase will contain a significant percentage of water, preferably at least about 60%, by weight of the internal polar phase, more preferably at least about 75% by weight, even more preferably at least about 85% by weight. % in weigh. In these embodiments, in addition to water, the internal water phase may comprise other water soluble or dispersible materials that do not adversely affect the water.

P710 stability of the inverted emulsion of high internal phase. A material of the type that is typically included in the internal water phase is a water soluble electrolyte. The dissolved electrolyte minimizes the tendency of the materials present in the liquid phase to dissolve also in the water phase. Any electrolyte capable of imparting ionic concentration to the water phase can be used. The electrolytes used include water-soluble monovalent or trivalent inorganic salts such as water-soluble halides, for example, chlorides, nitrates and sulfates of alkali metals and alkaline earth metals. Examples of electrolytes include sodium chloride, calcium chloride, sodium sulfate, magnesium sulfate, and sodium bicarbonate. The electrolyte will typically be included in a concentration in the range of from about 1 to about 20% of the water phase. Other water-soluble or water-dispersible materials, which may occur in the internal water phase, include thickeners and dispersity modifiers. Suitable thickeners and suitable viscosity modifiers include hydrophobically modified polyacrylic resins, water-soluble polyacrylic resins such as Carbopol and Pemulen, starches such as corn starch, potato starch, tapioca, gums such as gum P710 guar, gum arabic, cellulose esters such as hydroxypropyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, and the like. These thickeners and viscosity modifiers will typically be included in a concentration in the range of about 0.05 to about 0.5% of the water phase. Other water-soluble or dispersible materials that can occur in the internal water phase include polycationic polymers to provide steric stabilization to the water interface with lipid and nonionic polymers that also stabilize the water-in-lipid emulsion. Suitable polycationic polymers include Retén 201, Kymene R 557H and Acco 711. Suitable nonionic polymers include polyethylene glycols (PEG) such as Carbowax. These nonionic polycationic polymers will typically be included at a concentration in the range of from about 0.1 to about 1.0% of the water phase. In addition, or alternative to containing water, the internal polar phase may comprise polar materials, including solvents such as ethanol, isopropanol, butanol and hexanol; glycols such as substituted glycols such as propylene glycol, butylene glycol or hexylene glycol, polyglycols such as diethylene glycol or triethylene glycol; glycol ethers such as short chain derivatives (eg, C1-C6) of P710 oxyethylene glycol and oxypropylene glycol, such as n-hexyl ether of mono- and di-ethylene glycol, n-butyl ether of mono-, di- and tri-propylene glycol, and the like. All solvents, such as tetrahydrofuran, methyl sulfoxide, acetone and other miscible solvents substantially in water can be included in the internal polar phase. 3. Emulsifier Another key component of the high internal concentration inverted emulsion of the present invention is an emulsifier. In the emulsions of the present invention, the emulsifier is included in an effective amount. What constitutes an "effective amount" will depend on the number of factors including the respective amounts of the lipid and polar phase components, the type of emulsifier used, the level of impurities present in the emulsifier, and the like. Typically, the emulsifier comprises from about 1 to about 10% of the emulsion. Preferably, this emulsifier will comprise from about 3 to about 6% of the emulsion. Preferably, this emulsifier will comprise from about 4 to about 5% of the emulsion. While the individual "emulsifier" is used to describe this component, more than one emulsifier may be used when forming the P710 emulsion. In fact, as discussed below, it may be desirable to use a primary or secondary emulsifier when certain materials are used. While not intending to limit the scope of the invention, where two emulsifiers are used, it is preferred where the primary emulsifier comprises from about 1 to about 7%, preferably from about 2 to about 5% by weight, more preferably preferably from about 2 to about 4% by weight of the emulsion; and the secondary emulsifier comprises from about 0.5 to about 3%, more preferably from about 0.75 to about 2%, more preferably from about 0.75 to about 1.5% by weight of the emulsion. The emulsifier needs to be substantially lipid soluble or lipid miscible with the lipid phase materials, especially at the temperatures at which the lipid material is melted. It must also have a relatively low HLB value. Suitable emulsifiers for use in the present invention have HLB values typically in the range of about 2 to about 5, which may include mixtures of different emulsifiers. Preferably, these emulsifiers will have HLB values in P710 the range from about 2.5 to about 3.5. Suitable emulsifiers for use in the present invention include silicone polymer emulsifiers such as alkyl dimethicone-copolyols (e.g., Dow Corning Q2-5200 laurylmethicone-copolyol). These emulsifiers are described in detail in co-pending US Patent Application Serial No. 08 / 430,061 filed April 27, 1995 by L. Mackey (Case 5653), which is incorporated herein by reference. Other suitable emulsifiers are described in co-pending US Patent Application No. 08 / 336,456, filed November 9, 1994 by L. Mackey et al. (Case 5478), which is incorporated by reference herein. The emulsifiers described herein include certain sorbiton esters, preferably sorbitan esters of straight chain saturated or unsaturated fatty acids of 16 to 22 carbon atoms. Due to the manner in which they are typically manufactured, these sorbitan esters usually comprise mixtures of mono-, di-, tri-esters. Representative examples of suitable sorbitan esters include sorbitan mono oleate (eg, SPA-80), sorbitan sesquatose (eg, Arlacel "83), P710 sorbitan monoisostearate (eg, CRILLR 6 made by Croda), sorbitan stearates (eg, SPANR 60), sorbitan triolate (eg, SPANR 85), sorbitan tristearate (eg, SPAN "65) and dipalmitates of Sorbitan (eg, SPAN * 40) Laurylmethicone copolyol is a particularly preferred emulsifier for use in the present invention Other suitable emulsifiers described herein include glyceryl monoesters, preferably glyceryl monoesters of saturated chain fatty acids, saturated or branched, from 16 to 22 carbon atoms, such as glyceryl monostearate, glyceryl monopalmitate and glyceryl monobehenate; certain fatty acid esters of sucrose, preferably sucrose esters of saturated, unsaturated and branched chain fatty acids; to 22 carbon atoms such as sucrose trilaurate and sucrose distearate (eg, Crodesta "FIO), and certain polyglycerol esters of saturated, unsaturated or branched fatty acids of 16 to 22 carbon atoms such as glycerol monooleate and tetraglycerol monooleate. In addition, these primary emulsifiers can use co-emulsifiers to provide additional water-in-lipid emulsion stability, suitable co-emulsifiers include phosphatidyl cholines and phosphatidyl choline containing compositions such as P710 lecithins; long chain fatty acid salts of 16 to 22 carbon atoms, such as sodium stearate, short chain aliphatic quaternary ammonium salts of 1 to 4 carbon atoms, dialiphatic of 16 to 22 long-chain carbon atoms, such as dikebo-dimethyl-ammonium chloride and di-dimethylammonium methylsulfate; short chain dialiphatic quaternary ammonium salts of 1 to 4 carbon atoms, of dialcoyl (alkenoyl) -2-hydroxyethyl of 16 to 22 long-chain carbon atoms such as diclofoil-2-hydroxyethyl-dimethyl-ammonium chloride, the dialiphatic imidazolinium quaternary ammonium salts of 16 to 22 long-chain carbon atoms, such as methyl-l-baking-amido-ethyl-2-bait-imidazolinium methylsulfate and methyl-l-oleyl-amido-methyl sulfate ethyl-2-oleyl-imidazolinium; benzyl quaternary ammonium salts, monoaliphatic long-chain 16 to 22 carbon atoms, and short chain aliphatic carbon atoms such as dimethyl-steryl-dimethyl-benzyl-ammonium chloride, and synthetic phospholipids such as stearamide propi1-PG-dimonium chloride (Phospholipid PTS from Mona Industries). Interfacial tension modifiers such as cetyl and stearyl alcohol to pack more tightly into the outer inner phase of the polypeptide inner phase can also be included. Preferred emulsifiers useful in the P710 manufacture of the articles of the present invention include high viscosity emulsifiers described in co-pending US Patent Application No. 08 / 759,547, filed December 5, 1996 by L. Mackey et al. (Case 6062R), which is incorporated in the present by reference. These emulsifiers preferably have a viscosity at 552 C of at least about 500 centipoise. (Viscosity can be measured using a Brookfield rotary disk viscometer from Lab-Line Instrumens). This application specifically describes the use of emulsifiers such as those designated by Lubrizol Corporation (Wickliffe, OH) as OS-122102, OS-121863, OS-121864, OS-80541J and 0S-80691J, which are reaction products (i) a carboxylic acid substituted with hydrocarbyl or anhydride (preferably a succinic acid substituted with polyisobutylene or anhydride, and (ii) an amine or alcohol, to form an ester or amide product The materials, and methods for their manufacture are described in US Patent No. 4,708,753 issued on 24 November 1987 to Forsberg [see especially column 3, lines 32-38, and Column 8, line 10, column 26, line 68], and North American Patent No. 4,844,756, issued on June 4, 1989 to Forsberg, both of the which are incorporated by reference herein.

P710 Other materials believed useful in the present invention include hydrocarbon-substituted succinic anhydrides such as those described in U.S. Patent No. 3,215,707, issued November 2, 1965 to Rense; U.S. Patent No. 3,231,587, issued January 25, 1996 to Rense; U.S. Patent No. 5,047,175 issued to Forsberg on September 10, 1991; and World Patent Publication No. WO 87/03613, published by Forsberg on June 18, 1987. These publications are all incorporated by reference herein. Still other useful materials such as the emulsifier, particularly as a co-emulsifier with a high viscosity emulsifier, are the ABA block copolymers of 12-hydroxystearic acid and polyethylene oxide. These materials describe U.S. Patent No. 4,875,927, issued to T. Tadros on October 24, 1989, which is incorporated by reference herein. A representative material of this kind useful as an emulsifier herein is available from Imperial Chemical Industries PLC as Arlacel P135. While all of the materials described above can be used as an individual emulsifier, it may be desirable to employ more than one emulsifier when the emulsion is formed. In particular, P710 where a high viscosity emulsifier is used, a certain "sticky" feel can result when the treated article is subjected to the cutting pressures in use that break the emulsion. In this case, it may be desirable to use a co-emulsifier of a relatively lower viscosity with the primary emulsifier, to allow the use of a smaller amount of the main emulsifier, thereby relieving the stickiness. In a preferred embodiment of the present invention, a primary emulsifier available from Lubrizol (ie, reaction product of succinic acid substituted with polyisobutylene and an amine) and a secondary emulsifier which is an ABA block copolymer of poly-12- acid. hydroxystearic and polyethylene oxide (e.g. Arlacel P135 from ICI) are used to provide the emulsion with improved water retention levels over time, as well as beneficial reduced tack (via reduction in the level of the primary emulsifier). The person skilled in the art will recognize that different desired end uses will dictate whether multiple emulsifiers are appropriate, and the appropriate relative amounts of each if appropriate. This determination will require only routine experimentation by one skilled in the art in view of the present disclosure.

P710 4. Optional Emulsion Components The high internal phase inverted emulsions of the present invention may also comprise other optional components that are specifically resolutions containing moisture of this type. These optional components may be present in either the lipid, continuous phase or the internal polar phase and include perfumes, antimicrobials, eg, antibacterials, pharmaceutical actives, deodorants and pacifiers, astringents, skin moisturizers, and the like, as well as mixtures of these components. All these materials are well known in the art as additives for the formulations and can be employed in effective amounts, suitable in the emulsions of the present invention. A particularly preferred optional component that is included in the emulsions of wet-like cleaning tissues according to the present invention is glycerin as a skin conditioning agent. The emulsion component of the articles of the present invention is described and claimed herein in terms of the components (i.e., the components of the lipid phase, the components of the internal polar phase, the components of the emulsifier, etc. .) and the corresponding amounts of these components, which occur after the formation of emulsion. This is, P710 when the stable emulsion is formed and applied to the carrier. However, it is understood that the description (components and amounts) of the emulsion also covers the emulsions formed by combining the described components and levels, despite the chemical identity of the components after emulsification and application to the carrier.

C. Other Optional Cleaning Components In addition to the high internal phase inverted emulsion, there are other optional components that may be included in the articles of the present invention, typically for the purpose of improving the cleaning performance of the article when the internal polar phase of the emulsion is released. Certain of these optional components can not be present in the emulsion at significant levels (eg, greater than 2% of the polar internal phase) because they can cause premature breakdown of the emulsion. These include various anionic detergent surfactants having relatively high HLB values (eg, HLB from about 10 to about 25), such as sodium, linear alkylbenzene sulphonates (LAS), or alkyl ethoxy sulfates (AES), as well as nonionic detergent surfactants such as alkyl ethoxylates, P710 alkyl-amine oxide, alkyl polyglycosides, zwitterionic detergent surfactants, ampholytic detergent surfactants, and cationic detergent surfactants such as cetyl trimethyl ammonium salts, and lauryl trimethyl ammonium salts. See U.S. Patent No. 4,597,898 (Vander Meer), issued July 1, 1986 (incorporated herein by reference) especially columns 12 to 16 for anionic, nonionic, zwitterionic, ampholytic, and cationic, representative detergent surfactants. In contrast, these high HLB detergent surfactants can be applied or included in an article separately from the emulsion. For example, an aqueous emulsion of these high HLB detergent surfactants can be applied to the carrier either before or after application of the emulsion to the carrier. During the rinsing, the emulsion breaks down, releasing the internal polar phase (e.g., water), so that it can then be combined with the high HLB detergent surfactant to provide an improved hard surface cleaning. Although the description of the invention generally relates to the application of an individual emulsion to the carrier, it is recognized that two or more different emulsions can be used in the preparation of an individual article. In these embodiments, emulsions can P710 differ in a variety of ways, including, but not limited to, the ratio of the internal polar phase and the lipid phase, external, the emulsifiers used, the components used for either the internal and lipid phases, or both, and Similar. The use of multiple emulsions in an article may be particularly desirable when two or more components are incompatible with each other, but each is included in separate emulsions. Alternatively, if a particular reaction is desired at the time of use, reagents can be provided in separate emulsions. When cutting the emulsions during use, the desired reaction will occur. For example, where formation is desired during the rinsing process, a mild acid may be incorporated into the internal polar phase of an emulsion, while bicarbonate is incorporated into the internal polar phase of the second emulsion. When cutting the emulsions during use, the reagents interact to provide the desired foam.

Dj_ Preparation of the Articles Treated by the Emulsion In the preparation of the articles according to the present invention, the inverted emulsion of high internal phase is initially formulated. Typically, this is achieved by mixing or melting together the components of P710 lipid phase and the emulsifier. The particular temperature at which this lipid mixture is heated without an emulsifier will depend on the melting point of the components of the lipid phase. Typically, this lipid / emulsifier mixture is heated to a temperature in the range of from about 502 C to about 902 C, preferably from about 702 to about 802 C, before they are mixed, stirred or otherwise combined with the components of the water phase. The melted lipid / emulsifier mixture is then mixed with the polar phase components and then mixed together, typically under low cut conditions to provide the emulsion. This inverted emulsion of high internal phase is then applied in a fluid state in plastic at the temperatures indicated above to the carrier, for example, a paper mesh laminated to a polarophobic material. Any of a variety of methods that apply materials that have a fluid plastic consistency can be used to apply this emulsion. Suitable methods include spraying, printing (eg, flexographic or screen printing) coating (eg, gravure coating (extrusion, combinations of these application techniques, e.g., spraying the detergent surfactant into the mesh).

P710 paper, followed by the coating by etching the emulsion on the mesh treated with detergent. The emulsion can be applied to either or both surfaces of the carrier, or it can be applied to the internal surface (s) of the folds that make up the carrier. For example, in the case of a two-fold carrier where the hydrophilic substrate is a paper mesh with an internal surface treatment of GrapHsize (Akzo Chemicals Inc.) to provide a hydrophobic layer, the emulsion can be applied to the surface inner of the paper mesh, leaving the outer surface of the paper mesh free from the emulsion. This carrier design minimizes the transfer of wax and emulsifier to the wearer's skin which is especially desirable when high emulsion loads are used to provide more liquid for cleaning. For example, to provide the liquid level of a typical baby handkerchief, an emulsion charge of three times the carrier should be used. The application of the emulsion on both sides of the paper mesh substrate can be either sequential or simultaneous. Once the emulsion has been applied to the substrate, it is allowed to cool and solidify to form a typically discontinuous, solidified coating or film on the substrate surface. There are three fold handkerchiefs that can be P710 do with the central fold that is a hydrophobic sweep and the outer pleats that are hydrophilic meshes and paper. The emulsion can be applied to the inner surface of an outer fold (eg, substrate) and / or to a surface of the central barrier fold (hydrophobic) and the user will have a handkerchief with one side that is wet in use and the other which can be used for cleaning. Even in a package of tissues, the handkerchief drying side will remain dry because the aqueous fluid is not free to migrate as in wet non-encapsulated tissues. When a paper mesh is used as a hydrophilic substrate, the inverted emulsion of this internal phase is typically applied to the paper mesh and after the mesh has dried, i.e., the "dry mesh" addition method. The emulsion can be applied non-uniformly to the surface (s) of the materials constituting the carrier. By "non-uniform" it is meant that the amount, pattern of distribution, etc., of the emulsion may vary over the surface (s) of the material being treated. For example, some portions of the surface of a paper mesh may have greater or lesser amounts of the emulsion, including portions of the surface that do not have any emulsion. The inverted emulsion of high internal phase can be applied to the paper mesh P710 at any point after it has dried. For example, the emulsion can be applied to the paper mesh after it has been pleated from a Yankee dryer. Usually, it is preferred to apply the emulsion to the paper mesh as it is unwound from a roll of origin and before it is wound onto smaller, finished product rolls. In the application of high internal phase inverted emulsions for the carriers, vacuum coating and photoengraving methods are usually preferred. Figure 1 illustrates a preferred method where the emulsion is sprayed onto a carrier 10. With reference to Figure 1, this spray or spray system has a spray head 12 which applies a dispersed spray 14 of the emulsion on the carrier 10. This spray system is actuated by an assembly consisting of a ball screw unit 16 which is connected by the coupling 18 to a piston 26 of a hydraulic cylinder 22. A portion of the cylinder 22 is shown in Figure 1 as shown in FIG. filled with the inverted emulsion of high internal phase as indicated by 30. The cylinder 22 is heated to maintain the emulsion 30 in a fluid or plastic state. The emulsion 30 is introduced to the cylinder 22 via a 4-way coupling 34 having a line 38 connected to a filling orifice 42, P710 heated. The coupling 34 also has a line 46 which is connected to the pressure meter 50 and the spray head 12. There are three valves indicated as 56, 58 and 60 which control the flow of the emulsion in the lines 38 and 46. The system of The spray shown in Figure 1 also has a line 64 connected to the spray head 12 which allows the air generally indicated as 68 to be admitted to the spray head. Line 64 also has a pressure gauge and pressure regulator 72 for controlling and measuring air pressure in the line. Lines 64 and 46 are heated to maintain the emulsion in a molten state before application to the carrier. By filling the cylinder 22 with the emulsion 30, the valves 56 and 60 are closed and valve 58 is opened. The ball screw unit 16 is driven so that the piston 26 moves to the left. The vacuum created by the cylinder 22 extracts the emulsion from a filling hole 42 through a line 38 and up to the cylinder 22. To provide the emulsion from the cylinder 22 to the spray head 12, the valve 58 is closed and the valves 56 and 60 open. The ball screw unit 16 is driven so that the piston 26 moves to the right. This forces the emulsion 30 out of the cylinder 22 and up to the edge 46 of the coupling 34. The emulsion then passes through the valve 60 and up to the spray head 12 where it is dispersed P710 incorporating air from line 64 to provide dispersed spray 14 which is then applied to carrier 10. Figure 2 illustrates an alternative method for applying high internal phase inverted emulsion comprising a flexible gravure press system. With reference to Figure 2, a carrier 110 is unwound from the original fabric roll 112 (which rotates in the direction indicated by the arrow 112a) and is advanced around the rotation rolls 114, 116 and 118. turn 118, the carrier 110 is advanced to a rotogravure printing station indicated generally as 120 where the emulsion is then applied to both sides of the carrier. After leaving the station 120, the carrier 110 becomes a treated mesh indicated by 122. The treated mesh 122 is advanced to the surface rewinding roller 126 (which rotates in the direction indicated by the arrow 126a) and then rolled into roll 128 of the finished product (ie in the direction indicated by arrow 128a). Station 120 comprises a pair of rotogravure presses 130 and 134, likewise heated. The press 130 consists of a smaller anilox cylinder 138 and a larger pressure plate cylinder 142; the press 134 consists similarly of a smaller anilox cylinder 146 and a larger printing plate cylinder 150. The P710 Anilox cylinders 138 and 146 each have a ceramic or chrome surface, while the printing plate cylinders 142 and 150 each have a rubber with a relief pattern, polyurethane, or photopolymer surface. The anilox and printing plate cylinders rotate in the directions indicated by arrows 138a, 142a, 146a and 150a, respectively. as shown in Figure 2, the printing plate cylinders 142 and 150 are placed together and provide a roll separation area indicated by 154 through which the carrier 110 passes. The molten, hot emulsion is molded (FIG. for example, 60a C) to or sprayed on each of these rotogravure presses 130 and 134, linked in the roller separation areas indicated by arrows 158 and 162, respectively, at a constant volumetric flow rate. (Emulsion derived to presses 103 and 134 may be the same or different). In other words, the emulsion is added to the rotogravure presses 130 and 134, linked at the same speed as the emulsion that is applied to the carrier 110. This eliminates the "accumulation" of emulsion in the system. As the anilx cylinders 138 and 146 rotate in the directions indicated by the arrows 138a and 146a, they act as rotating doctor blades to spread the emulsion evenly across the surfaces of the cylinders 142 and 150 of P710 printing plate, respectively, and for removing the excess emulsion from the printing plates of the cylinders 142 and 150. The emulsion extending over the printing plate cylinders 142 and 150 (which rotate in the opposite direction as indicated by the arrows 142a and 150b) is then transferred to both sides of the carrier 110 in the roller separation area 154. The amount of the emulsion transferred to the carrier 110 can be controlled by: (1) adjusting the width of the roller separation area 154 between the printing plate cylinders 142 and 150; (2) adjust the width of the roller separation areas 158 and 162 between the cylinder pairs 138/142 and 146/150 anilox / printing plate; (3) the relief of the printing image (i.e., the valley depth) of the printing plate of the cylinders 142 and 150; (4) the printing area (i.e., the valley area) of the printing plate of the cylinders 142 and 150; and / or (6) the printing pattern of the printing plate of the cylinders 142 and 150.

C) Application of Emulsion to the Carrier The emulsion prepared in step A can be applied using the spray system shown in Figure 1. The emulsion is heated to the temperature of 602 C so that it becomes fluid or melted. The ball screw unit 16 is moved to a linear section of 0.002 inches / second as the piston 26 is operated (diameter P710 3.5 inches) to push the emulsion out of the cylinder 22 (emulsion pressure to approximately 12 psig). The emulsion goes to the spray head 12 (spray head with external mixing by spray adjustment SUE15 from Spray Systems Inc., Wheaton, Illinois) dispersed in the air (at 1.2 psig) heated to approximately 60 ° C.

The cylinders 142 and 150 then transfer the emulsion to both sides of the carrier 110. The coated carrier 122 is transferred to the surface rewinder roller 126 such that the coated central width of the carrier 122 is over the pressure area of the roller 126. As a result, the coated central width of the carrier 122 is not in contact with the surface of the roller 126, while the uncoated edges of the carrier 122 are in contact with the surface of the roller 126. The carrier 122 is then wound onto the finished product roller 128 .
