Abstract: An oil-in-water emulsion composition comprising 0.5% to 20% by weight of a cationic emulsifier, up to 75% by weight of siloxane and water, wherein the siloxane is liquid and has units according to the formula Ra Si O4−a/2 wherein R is hydrocarbon or OH and a is 0 to 3 and wherein the cationic emulsifier is free from halogen in its counter ion, preferably methosulphate, etho-sulphate, acetate, tosylate, phosphate or nitrate. The siloxane preferably has a viscosity at 25° C. of from 10,000 to 1,000,000 mPa.s and is selected from polydimethyl siloxanes and polydimethyl polymethyl phenyl siloxanes. Also covered is a process of depositing siloxanes from such siloxanes.
