Phosphoric and polyphosphoric acid esters

Phosphoric and Polyphosphoric Acid Esters, R(OC2H4)xOP(0)(0 M+)2 and [R(OC2H4)xO]2P(0)0 M+ Mainly phosphated POE alcohols and phenols, some sodium alkyl phosphates (not oxyethylenated). The POE materials are available in free acid form or as sodium or amine salts. Products are mixtures of monobasic and dibasic phosphates. [Pg.15]

The nonoxyethylenated monoalkyl phosphates cause little skin irritation and are used in personal care products. The sodium salt of monododecyl phosphate, unlike soap, works in a weakly acidic medium and can therefore be used as a detergent in face cleaners and cleansers and in body shampoos. The potassium or alkanol-ammonium salt of monohexadecyl phosphate is used as an emulsifying agent in skin care products. The dialkyl phosphate must be avoided in the synthesis of these products, since it reduces foaming and water solubility. [Pg.15]
