An oil-in-water emulsion composition comprising 0.5% to 20%nby weight of a cationic emulsifier, up to 75% by weight ofnsiloxane and water, wherein the siloxane is liquid and hasnunits according to the formula R a Si O 4-a/2 wherein R isnhydrocarbon or OH and a is 0 to 3 and wherein the cationicnemulsifier is free from halogen in its counter ion,npreferably methosulphate, etho-sulphate, acetate, tosylate,nphosphate or nitrate. The siloxane preferably has anviscosity at 25°C of from 10,000 to 1,000,000 mPa.s and isnselected from polydimethyl siloxanes and polydimethylnpolymethyl phenyl siloxanes. Also covered is a process ofndepositing siloxanes from such siloxanes. |
