Abstract
A superior skin barrier enhancing body facing material on an absorbent article, can be made applying, on the outer surface of the body facing material, a melted lipid-enriched hydrophilic composition comprising a hydrophilic solvent, a high molecular weight polyethylene glycol, a fatty alcohol (C14-C30 or greater), humectant, an oil-in-water emulsifying surfactant having an HLB range greater than 7, a sterol or sterol derivative, and a natural fat or oil, and thereafter resolidifying the composition to form a distribution of solid compositon on the outer surface of the body facing material.
Claims43
A body facing material having an outer surface, wherein said outer surface of said body facing material has a composition that enhances skin barrier consisting of:
- from about 10 to about 90 weight percent hydrophilic solvent;
- from about 5 to about 95 weight percent high molecular weight polyethylene glycol having a molecular weight of about 720 or greater;
- from about 1 to about 30 weight percent of a C14 to C30 or greater fatty alcohol;
- from about 0.5 to about 10 weight percent of humectant;
- from about 1 to about 20 weight percent of oil-in-water emulsifying surfactant having an HLB range greater than 7;
- from about 0.1 to about 10 weight percent of sterol or sterol derivative;
- and,
- from about 0.1 to about 30 weight percent of natural fats or oils.
A method of making a body facing material that enhances skin barrier having an outer surface consisting:
- (a) heating a composition consisting a hydrophilic solvent, a high molecular weight polyethylene glycol, a fatty alcohol, a humectant, an oil-in-water emulsifying surfactant having an HLB range greater than 7, a natural fat or oil, and a sterol or sterol derivative, to a temperature above the melting point of said composition, causing said composition to melt, said composition having a melting point of from about 30° C. to about 100° C.;
- (b) applying said melted composition to said outer surface of a body facing material web;
- and (c) resolidifying said melted composition.
A method for enhancing/restoring/maintaining skin barrier function skin of a user, comprising the steps of:
- a) contacting a body facing material on said skin of said user wherein said material comprises a skin barrier enhancing/restoring/maintaining composition that provides a skin barrier enhancing/restoring/maintaining benefit upon transfer of said composition to said user's skin;
- b) transferring at least a portion of said composition during use of said body facing material;
- and,
- c) repeating steps a) and b) with one or more additional body facing material with sufficient frequency to enhance/restore/maintain said skin barrier in an area of skin contacted by said body facing material, relative to skin contacted by an equivalent body facing material that does not comprise said skin barrier enhancing/restoring/maintaining composition,
- wherein said skin barrier enhancing/restoring/maintaining composition comprising:
- from about 5 to about 90 weight percent hydrophilic solvent, from about 5 to about 95 weight percent high molecular weight polyethylene glycol having a molecular weight of about 720 or greater, from about 1 to about 25 weight percent of a C14 to C30 or greater fatty alcohol, from about 0.5 to about 10 weight percent of humectant, from about 1 to about 20 weight percent of oil-in-water emulsifying surfactant having an HLB range greater than 7, and from about 0.1 to about 10 weight percent of sterol or sterol derivative.
