Benefits of technology

[0007]The invention, therefore, is directed to tissue and towel products, as well as other paper products such as wipes and non-woven materials, which minimize irritation and redness and other deleterious effects common to the repeated use of such products on the skin. A lotion which maintains the skin pH balance and provides a smooth, lubricious, non-greasy feeling layer on the skin, is transferred to the skin. More particularly, the invention relates to a tissue product treated with a lotion capable of maintaining skin pH balance comprising a skin pH balancing compound and a nongrease-feelng base lotion preferably containing an emollient and a retention / release agent as base ingredients. The base lotion has the effect of making the treated tissue product feel nongreasy and lubricious. Skin care benefits of the lotionized tissue product are expressed whether the product is used dry or prewetted with water.
[0014]Thus, in accordance with one aspect of the present invention, there is provided a lubricious, nongreasy-feeling lotionized tissue, wipe or nonwoven material, whereby the lotion transfers to the skin during use to provide a breathable, smooth layer which acts to maintain the skin acid mantle and the proper skin moisture / vapor balance and which users find soothing to irritated or damaged skin, and which users may find soothing to irritated skin and which may facilitate healing of chapped skin and skin suffering from discomfort, such as diaper rash or hemorrhoids. Preferably, the skin pH balancing compound is an organic acid, a combination of an organic acid and the salt of an organic acid, or a buffer combination.
[0018]In accordance with yet another aspect of the present invention, there is provided a lubricious, nongreasy-feeling lotionized tissue, wipe or nonwoven material, whereby the lotion forms a cold cream when contacted with water and transfers to the skin during use to provide a breathable, smooth layer which acts to maintain the skin acid mantle and the proper skin moisture / vapor balance and which users find soothing to irritated or damaged skin.

Problems solved by technology

We have discovered that existing lotionized tissue products are limited in their inability to maintain the pH balance of the skin.

examples 1-5

[0038]The lotion formulations compiled in Table 1 comprise a base lotion with and without a pH balancing compound. Examples 1 and 2 relate to a lotion without a pH balancing compound, and are included in Table 1 for comparison. Examples 3-5 relate to lotions obtained by adding a pH balancing compound to a base lotion according to the invention.

[0039]The lotions in Examples 3-5 were prepared according to the following procedure: the base lotion ingredients, i.e., emollient(s), release and retention agent and surfactants were mixed together and healed to 75° C. until the mixture was completely melted. The mixture was maintained at 75° C. for about 15 minutes with moderate agitation. The pH balancing compound was then added, using high agitation, until the compound was completely melted and blended. At this point the lotion was ready for application to the tissue product.

example 6

[0042]Example 6 provides a comparison of a lotionized tissue product containing a pH balancing compound in accordance with the present invention with other treated tissues. The lotionized tissue product was prepared by using the lotion formula described in Example 3. The lotion was applied on one-ply tissue (containing temporary wet strength agent) on a converting line. The results in Table 2 show that the invention (lotionized tissue with pH balancing glycolic acid) is the only tissue having pH balanced to skin pH. The pH of wetted tissue was determined by saturating 5 sheets of each product with 20 ml of tap water (pH=8.63). After 5 minutes, water in the tissue was removed by filtration, then measured for pH using a calibrated standard pH meter.

Abstract

A substrate treated with a lotion including a skin pH balancing compound and a base lotion. The pH balancing compound is preferably an organic acid, such as an alpha-hydroxy acid, an alpha-dihydroxy acid, or a beta-hydroxyacid, a combination of an organic acid and a salt of an organic acid, or a buffer combination, such as combinations of citric acid and disodium phosphate, or disodium citrate and sodium hydroxide. The preferred lotion has the effect of maintaining the skin acid mantle while making the treated substrate, preferably tissue, towel or napkin, optionally wet-strengthened, wipe or nonwoven material, feel smooth, lubricious and nongreasy. The skin care benefits of the lotionized substrate are expressed whether the product is used dry or prewetted with water.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to lotionized tissue and towel products which minimize irritation and redness and other deleterious effects common to the repeated use of such products on the skin.[0002]Absorbent tissue and towel products, such as facial tissue, bath tissue and paper towels, wipes and nonwoven materials have been used to absorb body fluids and cleanse and dry the skin. It has long been recognized, however, that products such as these tend to abrade and dry-out the skin causing uncomfortable irritation and redness. For example, there are numerous pre-moistened wipe products which can be found in the marketplace. However, many of these contain volatile alcohol solutions which remove skin lipids and fats, causing dryness.[0003]To reduce these deleterious effects, tissue products, e.g., tissue and towel products, wipes and nonwoven materials, have been provided with a variety of lotions and lubricant formulations enabling the products to better gl...
