Substrate Comprising A Composition Reducing The Adherence Of Feces Or Menses To The Skin

Abstract

A composition applied on a substrate comprised by, or forming, or used for manufacturing of, a disposable absorbent article may be used for reducing the adherence of feces or menses to the human skin. The composition deposited on the substrate does not affect negatively the manufacturing process of the disposable absorbent article and imparts desirable fluid handling properties to the substrate. The composition may also be desirably deposited on a substrate used as, or in a wipe.
