Patent ID: 8536296

Claim:
A process for making an aqueous emulsion of a silicone polyether having a viscosity greater than 10 kPa·s at 25° C. comprising: I) combining to form an oil phase; A) an SiH terminated silicone polyether copolymer having an HLB of less than 7 and an average formula HR 2 SiO(R 2 SiO) x R 2 Si—R 1 —[O(C m H 2m O) y ]—R 1 —SiR 2 O(R 2 SiO) x R 2 SiH wherein x is ≧0, m is from 2 to 4 inclusive, y≧4, R is a monovalent hydrocarbon group containing 1 to 20 carbons, R 1 is a divalent hydrocarbon containing 2 to 20 carbons, B) an organopolysiloxane having terminal unsaturated groups, C) a hydrosilylation catalyst, D) an emulsifier, II) admixing water to the oil phase to form an emulsion.
