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.

1. A method for delivering a cleansing agent and at least one active ingredient to a wet substrate selected from the group of wet skin or wet hair comprising contacting the wet substrate with a personal care article made of a flexible, three-dimensional, water-absorbent substrate material comprised of a web of substantially water-insoluble fibers, 1 where the personal care article is comprised of two halves, wherein (a) a first half is infused with 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 cationic quaternary surfactant (ii) at least one fatty alcohol, (iii) at least one emollient selected from the group consisting of cosmetically-acceptable oils, esters and liquid triglycerides, and (iv) at least one active ingredient and(b) a second half is infused with a solid cleansing agent that is a pourable soap having a melting point from about 50° C. to about 70° C. and is impregnated substantially throughout the interior of the flexible, three-dimensional, water-absorbent substrate, where the second half produces lather in both hard as well as soft waterwherein the first and second halves are joined, bonded, adhered, fastened or otherwise affixed to each other and further wherein the personal care article can be used multiple times. 2. The method of claim 1 where the cationic quaternary surfactant is selected from the group consisting of alkyl quats, alylamido quats, imidazoline quats and polymeric quats. 3. The method of claim 2 where the cationic quaternary surfactant is selected from the group consisting of behentrimonium methosulfate, distearyldimonium chloride, steapyrium chloride, lauramidopropyl PG-dimonium chloride phosphate and cocamidopropyl PG-dimonium chloride phosphate. 4. The method of claim 1 where the at least one fatty alcohol is a solid fatty alcohol. 5. The method of claim 4 where the at least one fatty alcohol is two solid fatty alcohols selected from the group consisting of cetyl alcohol, cetearyl alcohol and stearyl alcohol where the two solid fatty alcohols are present at a combined concentration of from about 55% to about 80% by weight of the solid anhydrous composition. 6. The method of claim 1 where the active ingredient is a skincare active or haircare active selected from the group consisting of emollients, humectants, occlusive conditioning agents, sunscreens or physical sunblocks, self-tanning agents, anti-inflammatory agents, antioxidants, vitamins and derivatives thereof, skin soothing agents and skin bleaching/lightening agents. 7. The method of claim 6 where the solid anhydrous composition further comprises an occlusive conditioning agent. 8. The method of claim 7 where the occlusive conditioning agent is petrolatum. 9. The method of claim 6 where the skincare active is a self-tanning agent and the solid anhydrous composition containing the self-tanning agent has a melting point of from 40 to 45° C. 10. The method of claim 1 where the at least one emollient is a liquid triglyceride. 11. The method of claim 10 where the at least one emollient is caprylic/capric triglycerides.
