    • 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.
    • 一种水包油乳液组合物,其包含0.5重量%至20重量%的阳离子乳化剂,至多75重量%的硅氧烷和水,其中所述硅氧烷是液体并具有下式的单位:R a Si O 4-a / 2其中R是烃或OH,a是0至3,并且其中阳离子乳化剂在其抗衡离子中不含卤素,优选为甲硫酸盐,硫酸氢盐,乙酸盐,甲苯磺酸盐,磷酸盐或硝酸盐。 硅氧烷优选在25℃下的粘度为10,000至1,000,000mPa.s,并且选自聚二甲基硅氧烷和聚二甲基聚甲基苯基硅氧烷。 还包括从这种硅氧烷沉积硅氧烷的方法。
