Patent ID: 7887834

Claim:
A process for making an aqueous composition consisting of; I) combining, A) 2 to 50 wt % of an (AB) n block silicone polyether copolymer having the average formula; —[R 1 (R 2 SiO) x (R 2 SiR 1 O)(C m H 2m O) y ] z — where x ranges from 30 to 75, y is greater than 4, the value of x/(x+y) ranges from 0.2 to 0.9, m is from 2 to 4 inclusive, z is greater than 2, R is independently a monovalent organic group, R 1 is a divalent hydrocarbon containing 2 to 30 carbons, B) 2 to 30 wt % of a water miscible volatile solvent selected from methanol, ethanol, isopropanol, or propanol, with sufficient amounts of water to provide the sum of the wt % of A), B), and water to equal 100% to form an aqueous dispersion, II) mixing the aqueous dispersion to form vesicles of the (AB) n silicone polyether copolymer having an average particle size of less than 10 micrometers, III) optionally removing the water miscible volatile solvent from the aqueous dispersion.
