Description

ABSORBENT TISSUES THAT PROVIDE AN INCREMENT OF SKIN BARRIER Field of the Invention The present invention relates to the inclusion of a hydrophobic lotion enriched with lipids on absorbent tissue products, such as facial tissue, bath tissue, paper towels and the like. More particularly, the present invention relates to the increase of a skin barrier function by the delivery of hydrophobic oil-based compositions from the absorbent tissue products to the skin.

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 acts as a barrier against chemicals and other stressors found in the environment. The complex arrangement of lipids in the intracellular space 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 is evident from the inflammation of the skin caused by the extraction of lipid from the skin.

The skin barrier can be damaged due to a number of mechanisms. Physical abrasion, for example caused by the repeated rubbing of absorbent tissue products on the skin, removes layers of the skin and therefore damages the skin barrier. Biological fluids, such as urine, feces, nasal and vaginal secretions, may contain a variety of components that can damage the skin barrier. Examples of these components include proteases, lipases, bile acids, and fatty acids. Once the skin barrier is compromised, these components, in addition to other constituents of biological fluids, can initiate or exacerbate skin inflammation.

Excessive hydration also has a negative impact on the skin barrier. Frequent skin contact with fluids such as nasal discharge can contribute to increased skin hydration. The increased skin hydration disrupts the lipid organization of the skin in the stratum corneum. This interruption can increase the permeability of the skin of the irritants, and therefore increasing the risk of inflammation of the skin.

Absorbent tissue products such as facial tissue and tissue paper have been used to absorb body fluids and leave skin dry. The absorbent tissue, in addition to absorbing the fluids, however, also scrapes the skin during use and frequently does not leave the skin completely dry and free of the body fluid that is trying to absorb the tissue. During the frequent sounding of the nose or perianal cleansing, for example, the skin may be scratched enough to appear red and painful to the touch. To reduce skin abrasion, tissue adhesive formulas can be applied to the tissue so that, in use, the additive formula either provides lubricity by causing the tissue to slip across the surface of the skin, or the tissue and deposit on the skin.

Once deposited on the skin, these additive formulas provide a benefit to the skin by occluding the skin. Therefore, these formulas provide a short-term benefit by providing an artificial barrier, even when the underlying stratum corneum has still been damaged.

Therefore, what is required in the art is a chemical formula that when applied from an absorbent tissue, increases the barrier function of the skin by delivering a lipid chemistry while minimizing physical damage caused by rubbing the skin. absorbent tissue on the surface of the skin.

Synthesis of the Invention It has now been discovered that the skin barrier-enhancing absorbent tissue product can be made by applying, on the tissue, an hydrophobic oil-based composition comprising a natural oil or fat, a sterol or sterol derivative, a humectant, an emulsifying surfactant having a hydrophilic and lipophilic balance range of from about 3 to about 6, an emollient, a wax, and optionally a viscosity enhancer and then resolidifying the composition to form a distribution, preferably a uniform distribution , of solid deposits on the surface or surfaces of the tissue. Because the composition is a solid at room temperature and solidifies rapidly after deposit, it has a tendency to penetrate and migrate into the sheet. Compared to the tissues treated with the liquid formulas, it leaves a larger percentage of the anhydrous solid lotion composition added on the surface of the tissue where it can make contact and transfer to the user's skin to provide increased skin health benefits. . In addition, a lower aggregate amount may be used to deliver the same benefit at a lower cost due to the efficient placement of the composition essentially on the surface of the product.

Optionally, the amount of viscosity increaser in the hydrophobic oil-based composition can be from about 0% by weight to about 25% by weight, more specifically from about 5% by weight to about 20% by weight. weight, and even more specifically from about 10 to about 15% by weight. As used herein, suitable viscosity builders include, but are not limited to the following materials: the group consisting of polyolefin resins, polyolefin polymers, ethylene / vinyl acetate copolymers, polyethylene and the like as well as mixtures thereof .

The resolidification of the hydrophobic composition based on melted oil can occur almost instantaneously, without the need for external cooling means, such as chill rolls, if the composition is heated to a temperature only slightly above or at the melting point of the composition. However, external media such as chill rolls, either before or after the application of the melt can be used if desired to accelerate the resolidification. Such instant resolidification tends to prevent the penetration of the composition into the tissue and to retain it on the surface of the tissue, which is advantageous. For example, the temperature of the molten composition may advantageously be above the melting point of about 10 ° C or less, more specifically about 5 ° C or less and even more specifically about 2 ° C or less. As the temperature of the molten composition approaches the melting point, the viscosity of the molten composition generally increases, which further increases the tendency of the molten composition to be retained on the surface.

For the purposes given here, the "melting point" is the temperature at which the majority of the melt occurs, recognizing that the melt actually occurs over a range of temperatures. The melting point of the compositions of this invention can be from about 30 ° C to about 100 ° C, more specifically from about 40 ° C to about 90 ° C, and even more specifically from about 80 ° C. 50 ° C to around 70 ° C.

In addition, for the purposes given here "penetration hardness" is the penetration of needle in millimeters according to ASTM D 1321, "Penetration of Oil Wax Needle". The lower needle penetration hardness values correspond to the harder materials. The penetration hardness of the compositions of this invention can be from about 5 millimeters to 360 millimeters, more specifically from about 5 to about 200 millimeters, more specifically from about 5 to about 150 millimeters, and yet more specifically from around 5 millimeters to around 100 millimeters. (Formulas that have a needle penetration hardness greater than 360 millimeters can not be measured using the ASTM D 1321 method).

The hardness of the formulas of this invention is important for two reasons. First, the softer the formula, the more mobile the formula will be, making the formula more likely to migrate to the inner layers of the tissue, which is undesirable. Second, softer formulas tend to be more greasy / oily to the touch which is also less desirable. In general, formulas that have a needle penetration hardness of from about 200 millimeters to 360 millimeters feel creamy to slightly greasy with less softness (depending on the additives). Formulas that have needle penetration hardness values of from about 5 millimeters to about 200 millimeters feel silky to creamy and very soft (depending on the additives).

The melt viscosity point and / or the process temperature viscosity of the formulas or compositions of this invention is important for two reasons: first, the higher the viscosity of the melting point or the viscosity of the process temperature applied to the outer surface of the diaper lining, the formula will be less feasible to penetrate through the stratum or inner layers of the tissue. The less penetrate the formula through the tissue, the more there will be on the surface of the tissue where it can be easily transferred to the surface of the skin of the users. Second, the higher the viscosity of the formula mentioned above or the melting point of the formula, the less likely it is that the formula will migrate to adverse or typical storage conditions.

In order to better increase benefits for consumers, additional ingredients can be used. The class of ingredients and their corresponding benefits include, without limitation, anti-acne assets (a drug product used to reduce the number of acne spots, acne pimples, black heads and white heads); agents against frothing (reduce the tendency to foam during processing); antimicrobial assets; antifungal assets; antiseptic assets; antioxidants (integrity of the product to avoid oxidation of natural oils or other ingredients of the formula); astringent-cosmetics (induce a tightening or scorching sensation on the skin); drug-astringent (a drug product which verifies exudate, discharge or bleeding when applied to the skin or mucous membrane and works by a coagulating protein); biological additives (increase the functioning or attraction to the consumer of the product including vitamins); dyes (impart color to the product); deodorants (reduce or eliminate unpleasant odor and protect against the formation of bad odor on body surfaces); emollients (help maintain the smooth, smooth and supple appearance of the skin by its ability to remain on the surface of the skin or in the stratum corneum to act as lubricants, to reduce scaling and to improve the appearance of the skin); film formers (to retain the active ingredients on the skin by producing a continuous film on the skin with drying); fragrances (attraction to the consumer); natural moisturizing agents (NMF) and other skin moisturizing ingredients known in the art; skin conditioning agents; skin exfoliating agents (ingredients that increase the rate of cell change of the skin such as alpha hydroxy acids and beta hydroxy acids); skin protectors (a drug product which protects the injured or exposed skin or the surface of the mucous membrane from harmful or annoying stimuli); solvents (liquids used to dissolve the components found useful in cosmetics or drugs); sunscreens (ingredients that absorb at least 85% of the light in the ultraviolet range at wavelengths of 290 to 420 nanometers, but transmit ultraviolet light at wavelengths longer than 420 nanometers); and surfactants (as cleaning agents, solubilizing agents, suspending agents, and wetting agents).

The aggregate of total tissue of the composition can be from about 0.5% by weight to about 40% by weight, more specifically from about 5 to about 30% by weight, and more specifically from about 10% by weight. about 15% by weight, based on the weight of the tissue. The amount of aggregate will depend on the desired effect of the composition on the attributes of the product and the specific composition. A preferred method for uniformly applying the heated composition to the tissue tissue surface is rotogravure printing, either direct or indirect (Off-center) because this is a more accurate and accurate printing process and offers maximum control of composition distribution and transfer rate. However, other printing methods may be used, but not limited to flexographic printing or spraying such as WEKO.

As used herein, all recited ranges of quantities, temperatures, molecular weights and penetration hardness are intended to include all sub-ranges within the ranges quoted, even if this is not specifically stated.

The term "non-uniformly" as used herein, refers to the amount, the pattern of distribution, the thickness of the application, the uncovered areas, or the like, for which the composition may be varied on the surface or surfaces outside of the tissue or towel product.

Also as used herein, a "tissue product" can be a facial tissue, a sanitary bathroom tissue, a paper towel, a paper napkin or the like. The tissue products of this invention can be one-stratum, two-stratus, three-stratum or more. In all cases, the composition is applied to one or both of the exterior surfaces of the product after the product has dried. The composition can be applied after the strata are put together or before the strata are put together. The individual layers can be layered or mixed (homogeneous), they can be creped or non-creped, dried continuously or wet pressed.

Example 4 Repetitive cleaning with an absorbent tissue treated with a formula enriched with hydrophobic lipid reduces barrier damage compared to an untreated absorbent tissue.

Absorbent tissue treated with a formula enriched with hydrophobic lipid was cleaned repetitively on the side of the face to determine the extent of barrier damage as measured by transepidermal water loss. The study consisted of repetitively cleaning the face of 10 panelists with the absorbent tissues for a total of 15 cleaning cycles. The cleaning cycles were ordered in time at approximately 30 minutes of separation with each cleaning cycle consisting of 20 cleaning cloths. A transepidermal water loss reading of the baseline and the transepidermal water loss readings after every two cleaning cycles were obtained from each panelist using the Dermalab evaporimeter. The change in transepidermal water loss between cleaning cycles was determined for each treatment. * Denotes statistically different than untreated absorbent tissue.

Repetitive cleaning with absorbent tissues treated with hydrophobic lipid enriched formulas results in less skin barrier damage compared to untreated absorbent tissue.

Thus, the examples representatively illustrate that the hydrophobic lipid-enriched composition of the present invention can provide absorbent tissue products having improved softness as well as improved protection of skin barrier function. Thus, different aspects of the present invention can advantageously provide absorbent tissue products which, when compared to conventional tissue products, are softer and have improved protection of the skin barrier function. Such absorbent tissue products can advantageously be used for absorbent tissue products, such as facial tissue, bath tissue, paper towels and the like.
