Patent ID: 8729183

Claim:
An emulsion of polyorganosiloxanes comprising (A) at least one polyorganosiloxane having a viscosity greater than 10,000 mm 2 /s, measured at 25° C., (B) at least one emulsifier of the formula (RO) n P(O)(OH) (3-n) (I), in which R are the same or different and are monovalent hydrocarbyl radicals having 4 to 30 carbon atoms, n is 1 or 2, and/or salts thereof, (C) at least one emulsifier selected from the group consisting of (C1) ethoxylated triglycerides having 40 to 400 oxyethylene groups, (C2) ethoxylated sorbitan esters of fatty acids having 12 to 18 carbon atoms and 10 to 40 oxyethylene groups, (C3) compounds of the formula R 1 —O—(CH 2 CH 2 O) m —H (II) and (C4) compounds of the formula R 2 CH 2 C(O)—O—(CH 2 CH 2 O) p —H (III), in which R 1 is a linear alkyl radical having 10 to 30 carbon atoms, R 2 is an alkyl radical having 10 to 30 carbon atoms, m is from 15 to 100 and p is from 15 to 100, and (D) water, with the proviso that the emulsion contains less than 2% by weight of octaorganylcyclotetrasiloxane (D 4 ), based on the weight of component (A).
