Abstract

The present patent application relates to a single-use cosmetic article containing a water-insoluble substrate impregnated with an aqueous cosmetic composition, said substrate being permeable and containing at least a first group of fibers and at least a second group of fibers whose hydrophilicity is different from that of the fibers of the first group. The first and second groups of fibers are arranged such that a first face of the substrate has a hydrophilicity substantially greater than the hydrophilicity of a second face of the substrate, opposite the first face.
