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 μm and a hydrophobicity measured by a contact angle between about 20° to 140°. 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. |
