Abstract

Aqueous dispersions of silicone oils are prepared without the need for surfactants, solvents, hydrotropes or emulsifiers by employing water soluble and/or water dispersible polymers providing inventive compositions which exhibit a rheological Critical Strain value greater than zero and less than about 0.5. Disclosed according to the present invention are compositions and methods of use of the aqueous dispersions of silicone fluids for cleaning, preserving, protecting, and otherwise treating a variety of surfaces, including household surfaces, such as floors, counter tops, furniture, walls, and automotive surfaces, such as tires, rubber, vinyl, upholstery, fabric, plastic and general elastomer surfaces.
