摘要:
Personal care compositions comprising responsive particles. In one aspect, the responsive particle comprises: (1) a particle core having an interfacial surface, (2) a first polymer having a first property, and (3) a second polymer having a contrasting property. The first polymer and the second polymer are attached at different locations to the interfacial surface of the particle core. In another aspect, the responsive particle comprises: (1) a particle core having an interfacial surface, (2) at least one block co-polymer comprising a first block and a second block, wherein said first block has a first property and said second block has a second property, and (3) optionally, at least one other polymer having a third property. The block co-polymer and the optional other polymer (if present) are attached to the interfacial surface of the particle core, and at least one of the properties contrasts. The personal care compositions also comprise a dermatologically acceptable carrier. Also disclosed are methods of making responsive particles.
