Abstract
A method of forming an MT-propyl siloxane resin includes the steps of hydrolyzing propyl trichlorosilane in an excess of water to provide a T-propyl siloxane resin and capping the T-propyl siloxane resin formed from the hydrolysis of the propyl trichlorosilane with a silicon-containing M-group capping agent to form the MT-propyl siloxane resin. The MT-propyl siloxane resin is useful in a variety of personal care applications, and in particular, as an additive to personal care compositions.
