Patent ID: 7678301

Claim:
A process for making a vesicle composition comprising; I) combining, A) 2 to 25 wt % of a silicone polyether copolymer having a structure represented by: where R1 represents an alkyl group containing 1-6 carbon atoms; R2 represents the group —(CH 2 ) a O(C 2 H 4 O) b (C 3 H 6 O) c R3; x is 251-1,000; y is 1-500; z is 1-500; a is 3-6; b is 4-20; c is 0-5; and R3 is hydrogen, a methyl group, or an acyl group, B) 2 to 30 wt % of a water miscible volatile solvent, C) water in a sufficient amount to provide the sum of the wt % of A), B), and C) to equal 100%, to form an aqueous dispersion of the silicone polyether copolymer, II) mixing the aqueous dispersion to form a vesicle composition having an average particle size of less than 0.500 micrometers, III) removing the water miscible volatile solvent from the vesicle composition.
