摘要

A method for delivering active ingredients to a wet substrate from a flexible, three- dimensional, water-absorbent substrate material comprised of a web of substantially water-insoluble fibers into which is infused a solid anhydrous composition having a melting point of from about 45°C to about 55°C said anhydrous composition comprising (i) at least one surfactant selected from the group consisting of cationic quaternary surfactants, anionic surfactants or nonionic surfactants or one multi-lamellar liquid crystal emulsifier system, (ii) at least one fatty alcohol, (iii) at least one emollient selected from the group consisting of cosmetically-acceptable oils, esters and liquid triglycerides, (iv) at least one active ingredient and (v) optionally, a solid cleansing agent having a melting point from about 50°C to about 70°C. Preferred active ingredients are skincare and haircare actives, including emollients, humectants, conditioning agents, sunscreens and sunblocks, and artificial tanning agents.
