Abstract
A rinse off hair conditioning composition comprising: (a) about 0.05 to about 5% by weight of cationic surfactant, (b) 0.01 to 10% by weight of an emulsion polymerised dimethiconol nonionic conditioning polymer having the formula: HO—Si(CH3)2—O—[Si(CH3)2—O—]nSi(CH3)2—OH where n is greater than 2700, and (c) water. The invention also comprises a method of making a conditioning composition.
Claims9
A rinse off hair conditioning composition substantially free from anionic surfactant comprising:
- (a) about 0.05 to about 5% by weight of cationic surfactant,
- (b) 0.01 to 10% by weight of an emulsion polymerized dimethiconol nonionic conditioning polymer with viscosity in the range 1 to 20 million cst and having the formula:
- HO—Si(CH3)2—O—[Si(CH3)2—O—]nSi(CH3)2—OH
- where n is greater than 2700, and
- (c) water.
A composition according to any preceding claim wherein the cationic surfactant is selected from the group comprising cetyl trimethyl ammonium chloride and behenyl trimethyl ammonium chloride.
A method for preparation of a rinse off conditioning composition which comprises a cationic surfactant and insoluble silicone which is a dimethiconol polymer having a molecular weight above 200,000 and a viscosity of greater than 1 million cst as conditioning agent comprising the steps of forming the silicone into an emulsion, the emulsion having a viscosity of less than 1000 cps, then mixing the emulsion with the cationic surfactant.
