PERSONAL CARE COMPOSITIONS CONTAINING A WATER-DISINTEGRATABLE POLYMERIC FOAM

摘要

Disclosed are personal care compositions for topical application to the hair or skin, and corresponding methods of application, said compositions and methods comprising or are directed to a solid polymeric foam containing (A) a solid polymer-containing structurant having a defined water solubility and/or dissolution profile; and (B) an active ingredient comprising a surfactant in a weight ration of the surfactant to the solid polymer structurant of from about 1:8 to about 10:1, preferably 1:1.6:1 to about 10:1; wherein the solid polymeric foam disintegrates in water in accordance with a Substrate Disintegration Test such that no individual foam pieces remain after disintegration that have a topographical area of more than about 10% of the topographical area of the solid polymeric foam prior to application with water. The disclosed compositions and method provide effective topical delivery of active ingredients from a solid polymeric foam substrate that slowly disintegrates and is rinsed away during prolonged single-use or other similar application, such as showers or baths.
