Description

WET CLEANING CLOTHES HAVING SKIN HEALTH BENEFITS Field of the Invention The present invention relates to wet cleaning cloths and cleaning cloth type products. More particularly, the present invention relates particularly to wet cleaning cloths and cleaning cloth-type products that can be used for a variety of purposes including cleaning, cosmetics removal, and sanitation comprising an emulsion composition solution of Oil in water that cleanses the surface of the skin and provides increased skin health benefits.
Background of the Invention The stratum corneum is the outermost layer of the skin and is responsible for the regulation of water levels in the skin and works as a barrier against chemicals and other stressors found in the environment. The complex arrangement of lipids in the space between the cells of the stratum corneum is responsible for the establishment of a normal barrier function. The multi-layered structures of cholesterol, ceramides, and fatty acids, as well as some other minor lipids, provide the main barrier to the transport of hydrophilic substances in or through the skin. The link between barrier function and skin health can be seen through the inflammation of the skin that results from the extraction of lipids from the skin.
In addition to the information, the interrupted barrier function can result in a number of skin conditions, most notably, dry skin. Humidifiers that consist of humectants or occlusive chemicals are commonly used to treat dry skin.
Diaper dermatitis, in infants and adults, is a genre of skin conditions that, in large part, originates from a damaged barrier function. Skin barrier damage can result from a variety of factors, including: Increased skin hydration due to skin occlusion caused by diapers, enzymatic skin damage due to fecal and urinary enzymes, physical abrasion caused by diapers, wash cloths, and wet cleaning cloths, and the removal of lipids from the skin by a surfactant associated with bathing and cleaning.
Occlusion of the skin results in increased hydration of the skin due to blockage of evaporative water lost from the surface of the skin. The level of hydration of the skin wrapped in diapers can reach between five to ten times that of a skin without diapers. Frequent skin contact with diapers with urine can also help increase skin hydration. Increased skin hydration disrupts the organization of skin lipids in the stratum corneum. This interruption may increase the permeability of the skin allowing the penetration of irritants from the stool and urine inside the skin.
The results of the studies carried out on hairless mice reveal that fecal enzymes, specifically proteases and lipases, are the main irritants of the skin in a skin environment with diapers. Faecal proteases degrade stratum corneum proteins resulting in inflammatory reactions and in facilitating the penetration of low molecular weight irritants. It was observed that urine raises the pH of the skin thus facilitating the enzymatic action on the skin as well as causing inflammatory reactions in the skin.
The skin with diapers is typically cleaned by the application of cotton wash cloth or by means of disposable wet wipes. The effect on the skin of the wet cleaning cloths depends on the materials and the surfactant systems used for the cleaning cloths. The skin with diapers is usually cleaned several times a day with cleaning cloths using solutions containing surfactants. Surfactants are known to remove lipids from the stratum corneum or disrupt the lipid structure within the stratum corneum, thus decreasing the barrier function. The cleaning cloth and the cleaning cloth type product material can cause damage by physical abrasion to the skin and can lead to an increase in the transpidermal water loss, an indication of the diminished barrier function. Other cases from which the breakdown of skin barrier function results are frequent hand washing and contact dermatitis that originates from harsh surfactants and other chemical irritants.
Once the skin barrier has been compromised, a series of events can occur within the skin to synthesize and organize the lipids to restore the function of the barrier. The body naturally repairs defects in the function of the skin barrier by increasing the production of key lipids found in the skin, such as cholesterol, ceramides, and fatty acids, and key lipid synthesizing enzymes. Two known environmental conditions inhibit the natural skin barrier repair mechanisms in relation to a skin wrapped in diapers. The first condition is a pH of neutral skin, and the other condition is the occlusion of the skin. Chronic exposure to faeces and urine, as well as continued occlusion of the skin, therefore leads to the chronic interruption of the skin's barrier function.
Wet cleaning cloths are well-known commercial consumer products that have been available in many forms. Perhaps the most common form of wet cleaning cloths has been a moistened pile of leaves that have been packed in a plastic container. Wet cleaning wipes have been made from a variety of materials that have been moistened with a variety of mild and suitable surfactant based solutions. Such wet cleaning cloths have been used for baby wipes, hand wipes, household wipes, industrial wipes, body wipes and face wipes, and the like.
Typically, such conventional cleaning cloths have included a single layer of an essentially homogeneous material. For example, conventional wet wiping cloths have included a fabric of air-laid fibers that are mixed or evenly distributed throughout the fabric. Wipers have included polymeric fibers such as polyester, polyethylene and polypropylene and natural or synthetic fibers such as cellulosic fibers. Other conventional wet wiping cloths have included a woven fabric of polypropylene and cellulosic fibers wherein the fibers are uniformly mixed through the fabric.
However, other forms of the wet cleaning cloth or cleaning cloth type products include a cleaning cloth product having a nonwoven layered base sheet. The layered base sheet may include at least two layers placed in a front relationship with one another, wherein one of the layers includes fibers that are not included in the other layer. Such an arrangement can be where at least one of the layers includes polyethylene fibers and at least one of the layers includes polypropylene fibers. In alternate forms, the layers may include similar materials, but in different amounts. The different layers may be configured to provide different physical properties, such as the softness for the cleaning cloth product while another layer may be configured to provide other properties, such as strength, to the cleaning cloth product.
The balance of physical properties, such as softness, flexibility, strength, integrity and elasticity has not been fully optimized. The topical chemistry can be used to increase the properties of the delivered product of the wet cleaning cloths of the cleaning cloth type products. This has been particularly true for those users who want improved skin health or the ability to impart health benefits to the skin. The skin health benefits of the cleansing cloth product or the skin health benefits imparted by the cleansing cloth product may be perceived as being particularly important for cleansing wipes for the body which are intended for repeated contact with the skin. the skin of an adult to an infant.
Therefore, what is required in the art are products that help to maintain the skin's barrier function, particularly in the skin environment with diapers, such as a wet cleaning cloth product or cleaning cloth type that: a) deposit adequate chemicals on the skin to increase the skin barrier; b) minimize physical damage to the skin due to the cleaning cloth; c) leave the feeling of soft and docile skin; and d) provide a long-lasting benefit until the next cleaning event while effective cleansing is still provided while providing an increase in skin barrier.
Synthesis of the Invention It has now been discovered that an improved cleaning cloth or wiper cloth product, used for a variety of purposes, including cleaning, cosmetics removal and sanitation, that increases the skin barrier can be made by applying, absorbing inside. or otherwise moistening the wet cleaning cloth or the cleaning cloth type product with an oil-in-water emulsion composition comprising a natural fat or oil, sterol or a sterol derivative, a humectant, emulsifying surfactants and surfactant combinations that They have a range of hydrophilic and lipophilic balance of around 7 to about 18 and water. The composition is also easily transferred from the wet cleansing diaper or from the cleansing cloth type sheet to the skin being contacted with the sheet to provide increased skin barrier benefits while providing a desired product purpose. .
Therefore, in one aspect, the invention relates to an oil-in-water emulsion composition comprising from about 0.1 percent by weight to about 30 percent by weight of natural fats or oils, from about 0.1. percent by weight to about 10 percent by weight of a sterol or a sterol derivative, from about 0.1 weight percent to about 99.5 weight percent of a humectant, and from about 0.5 to 0.5 weight percent; about 20 percent by weight of an emulsifying surfactant that has a range of hydrophilic and lipophilic balance of around to about 18, from about 45 to about 99.5 percent by weight of water and the pH of the adjusted emulsion at a pH of about 4 to about 7.

The wet wiping cloths of the present invention comprise a single layer or a layered base sheet containing a liquid. The liquid is typically any solution which can be absorbed into the base sheet of the wet cleaning cloth and can include any suitable components which provide the desired cleaning cloth properties. Typically, the components have included water, emollients, surfactants, fragrances, preservatives, chelating agents, pH buffers or combinations thereof as are well known to those skilled in the art. The liquid also contains certain medications and / or lotions. The emulsion composition of the present invention is more specifically designed to provide improved skin health benefits, such as increased barrier function and skin protection.
The amount of the oil-in-water emulsion composition of the present invention contained within each cleaning cloth may vary depending on the type of material used to provide the cleaning cloth or the cleaning cloth type product, the type of container being used. used to store the wet cleaning cloths, and the desired end use of the wet cleaning cloth. Generally, each cleaning cloth or cleaning cloth type product may contain from about 100 to about 600% by weight and desirably from about 250 to about 450% by weight of liquid based on the dry weight of the cleaning cloth to improve the cleanliness. In a particular aspect, the amount of liquid contained within the cleaning cloth is from about 300 to about 400% by weight and desirably from about 330% by weight based on the dry weight of the wet cleaning cloth. If the amount of liquid is less than the above identified ranges, the cleaning cloth can also be very dry and may not work properly. If the amount of liquid is greater than the ranges identified above, the cleaning cloth may be supersaturated and soaked and the liquid may stagnate at the bottom of the container.
Each wet cleaning cloth is generally rectangular in shape and can have any suitable width and bent lengths. For example, the cleaning cloth may have a split length of from about 2.0 to about 80.0 centimeters and desirably from about 10.0 to about 25.0 centimeters and an unfolded width of from about 2.0 to about 80.0 centimeters and desirably from from around 10.0 to around 25.0 centimeters. Typically, each individual wet cloth is arranged in a folded configuration and stacked on top of each other to provide a stack of wet cleaning cloths. Such bent configurations are well known to those of ordinary skill in the art and include the configurations bent in c, bent in z, bent in fourth and the like. The stack of folded wet cleaning wipes can be placed inside a container, such as a plastic tube to provide a package of wet wiping cloths for eventual sale to the consumer. Alternatively, the wet wiping cloths may include a strip of continuous material which has perforations between each wiping cloth and which can be arranged in a stack or rolled in a roll for the assortment.
However, the product of wet cleaning cloth or cloth type can assume a variety of shapes including but not limited to the generally circular, oval, square or irregularly shaped shape. The size of the type of cleaning cloth or wet cleaning cloth will also vary from the desired end use of the cleaning cloth.

In addition, materials can be formed into balls, such as cotton balls or applied to delivery systems such as scouring applicators.
If a layer of the base sheet is a combination of polymeric and natural fibers, such as polypropylene and cellulosic fibers, the relative percentages of the polymer fibers and natural fibers in the layer can vary over a wide range depending on the characteristics desired of the wet cleaning cloths. For example, the layer may comprise from about 20 to about 95% by weight, desirably from about 20 to about 60% by weight, and more desirably from about 30 to about 40% by weight of polymer fibers based on the dry weight of the layer. Such a layer of natural and polymeric fibers can be manufactured by any method known to those skilled in the art.
Generally, it is desirable that such a layer be formed by a coform process for a more uniform distribution of the polymeric and natural fibers within the layer. Such coform layers are generally manufactured as described in U.S. Patent No. 4,100,324 issued to Anderson et al. On July 11, 1978; U.S. Patent No. 4,604,313 issued to MacFarland et al. on August 5, 1986 and U.S. Patent No. 5,359,624 issued September 27, 1994; all of which are incorporated herein by reference in the extent to which they are consistent therewith.
Typically, such coform layers comprise a matrix formed of melt-blown microfiber thermoplastic polymeric microfibers, such as, for example, polypropylene microfibers and cellulosic fibers, such as, for example, wood pulp fibers. A coform layer is formed by initially forming at least one primary air stream containing the synthetic or polymeric fibers and fusing the first stream with at least one secondary stream of natural or cellulosic fibers. The primary and secondary currents are fused under turbulent conditions to form an integrated stream that contains a homogeneous and complete distribution of the different fibers. The integrated air stream is directed to a forming surface to form the material layer with air. A multiplicity of these coform layers can be formed in succession to provide a fabric of multiple coform layers.
The different fibers in the different layers of the layered base sheet of the present invention, such as the polypropylene and polyethylene microfibers set forth above, typically may not be compatible with each other and may not bond to one another. However, the different fibers may become entangled with one another resulting in adequate securing between the layers. For example, in a layered base sheet containing a coform layer of polyethylene and cellulosic fibers and a coform layer of polypropylene and cellulosic fibers, the polyethylene and polypropylene fibers can become entangled with each other and the cellulosic fibers can bind at least partially to the cellulosic fibers which results in an assurance between the layers.
Such an interlayer and entanglement bond can be increased by means of thermomechanical processes wherein the layered base sheet is passed between a smooth anvil roller and a heated pattern roller. The pattern roller may have any highlighted pattern which provides the desired entanglement and interlayer bond. Desirably, the patterned roller defines a raised pattern which defines a plurality of bonding sites which define a bonding area of between about 4 and about 30% of the total roll area for improved interlayer fastening.
The base sheet for cloths or wet cleaning cloth type products can have a total basis weight of from about 25 to about 120 grams per square meter and desirably from about 40 to about 90 branches per square meter. Such base weight of the layered base sheet can also vary depending on the desired end use of the cleaning cloth or the wiper type products. For example, a base sheet suitable for cleaning the skin can define a basis weight of from about 60 to about 80 grams per square meter and desirably about 75 grams per square meter. In a particular embodiment wherein the base sheet includes the polypropylene coform layers and the cellulosic fibers and the polyethylene and cellulosic fibers, the base sheet in layers defines a basis weight of from about 60 to about 90 grams per meter square and desirably about 80 grams per square meter for improved smoothness and adequate strength.
In a particular embodiment, it is desired that the wet cleaning cloth of the present invention defines a strength sufficient to withstand the forces exerted by the user when the latter is moistened with the solution. For example, the base sheet for wet cleaning cloths or cleaning cloth type products can define a tensile strength of at least about 1.23 newtons per centimeter in the machine direction and at least about 0.70 newtons per centimeter in the direction transverse to the machine. Cleaning cloths or the type of cleaning cloth that has alternate ranges of tensile strength can also be effectively employed. As used herein, the term "machine direction" refers to the direction in which the materials are manufactured while the direction transverse to the machine refers to a direction which is perpendicular to the machine direction.
In a particular embodiment, wherein the base sheet includes the coform layers of polypropylene and cellulosic fibers and polyethylene and cellulosic fibers, the base sheet in layers defines a tensile strength of from about 1.31 to about 3.50 newtons per centimeter in the machine direction and from about 0.84 to about 1.40 newtons per centimeter in the direction of the cross machine and desirably from about 1.58 to about 1.93 newtons per centimeter in the machine direction and from about 0.93 to about 1.11 newtons per centimeter in the cross machine direction. In such a configuration, the coform layer which includes the polypropylene fibers provides the majority of the strength to the base sheet while the coform layer which includes the polyethylene fibers provides a smooth surface for contact with the wearer's skin. Thus, the tensile strength of such a layered base sheet is superior to the tensile strength of a single layer containing polyethylene fibers and which provides a smoother surface than a single layer containing polypropylene fibers.

The test formulas (15 microliters) were added to the surface of the EpiDermMARCA skin model and incubated for 30 minutes at 37 ° C, 5% C02 before dosing with the fecal enzyme, trypsin. The study was conducted using an Epi-200 assay medium devoid of hydrocortisone and a pH indicator that was prepared by the manufacturer. After 30 minutes, the underlying medium was removed and replaced with a fresh preheated medium followed by the application of 10 microliters of 200 μg / ml trypsin. The skin wells were incubated for 6 hours before the underlying medium was removed and stored for further analysis. The medium was assayed for the permeated trypsin content using a fluorescent substrate (Boc-Gin-Ala-Arg-AMC.HCl, from Bachem California, Inc., of Torrance, California) specific for trypsin-like activity. Also, the amount of IL-la in the medium was measured using the commercially available ELISA kits (Quantikine ^ 11 ^ Human IL-la Immunoassay, R &D Systems, of Minneapolis, Minnesota) specific for IL-la to assess the capacity of the formulas to avoid a proinflammatory response by the enzyme in comparison to the control without treatment.
Table 1.1: Irritation: Proinflammatory response (IL-la) Table 1.2: Permeated Trypsin Formulas 1 and 2 increased the skin barrier of the EpiDermMARCA skin model against trypsin and reduced the proinflammatory response as measured by IL-la after 6 hours compared to trypsin control.
