Patent ID: 8865144

Claim:
A personal care composition comprising: (a) a responsive particle, wherein said responsive particle comprises: (1) a particle core having an interfacial surface; wherein said particle core is an inorganic particle core selected from the group consisting of titanium dioxide, silica, iron oxides, zinc oxide, micas, zeolites, boron nitride, talc and mixtures thereof; (2) a first polymer, wherein said first polymer is polyethylenimine; and (3) a second polymer, wherein said second polymer is aminopropyl-terminated polydimethylsiloxane wherein said first polymer and said second polymer are covalently attached to the interfacial surface of said particle core at different locations on said interfacial surface; wherein the properties of the responsive particle change in response to changes in the environment; and wherein the properties of the responsive particle are selected from the group consisting of surface energy, hydrophilicity, hydrophobicity, acidity, basicity, and charge; and (b) a dermatologically acceptable carrier.
