Abstract
A clear shampoo is described which contains a cationic oil-in-water emulsion of an amine functional polydimethyl silicone, and a method of making clear and stable shampoo compositions, in which an emulsion of an amine functional siloxane can be added to a shampoo composition without causing cloudiness, and without contributing instability to the shampoo composition whereby phase separation occurs. In accordance with the method, an emulsion of an amine functional siloxane is added to a shampoo composition without the necessity of requiring that a pearling agent be employed for the purpose of disguising cloudiness.
