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

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.
