A foam manipulation stabilizing composition for use in consumer products includes a plurality of surface-modified particles in combination with at least one surfactant. The particles have an average particle size greater than 100 nm up to about 50 &#x3bc;m and a hydrophobicity measured by a contact angle between about 20&#xb0; to 140&#xb0;. The ratio of particles-to-surfactant may be between about 1:20 to about 20:1. The surface modification may include grafting pH or temperature switching functional groups to the particles or to a composition, such as a polymer, coated on the particle. A method for reducing the level of foam in a rinse solution is also described.

Foam manipulation compositions containing fine particles

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.

Personal care compositions comprising responsive particles

A responsive coated substrate, said substrate comprising an interfacial surface to which a responsive coating attaches, said responsive coating comprising (a) at least one silicone-based, substantially hydrophobic polymer and (b) at least one substantially hydrophilic polymer wherein said responsive coating substrate is in a first state; and methods of coating the same.
