Claim:
A composition comprising: a) colloidal silica core/silicone shell particles comprising (i) about 90 wt % to about 10 wt % cores of colloidal silica and (ii) about 10 wt % to about 90 wt % shells of a polyorganosiloxane having the formula M a D b T c Q d with M a =(R 1 )(R 2 )(R 3 )SiO 2/2 D b =(R 4 )(R 5 )SiO 2/2 , T c =(R 6 )SiO 3/2 , Q d selected from the group consisting of (OH) SiO 3/2 or SiO 4/2 where R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 are each independently selected from the group consisting of OH, linear or branched monovalent hydrocarbon radicals of 1 to 30 carbons, monovalent arylalkyl, aryl cyclics hydrocarbon radicals where the ratios of M to D to T to Q are according to the following relationships: 0<( a/d )<2; 0.1<( b/d )<10; 0<( c/d )<10; b) a polyalkyleneoxide modified trisiloxane having the formula: M 1 e D 1 f D 2 g M 2 h with M 1 e =R 7 R 8 R 9 SiO 1/2 ; M 2 h =R 10 R 11 R 12 SiO 1/2 ; D 1 f =R 13 R 14 SiO 2/2 ; D 2 g =R 15 R 16 SiO 2/2 ; where R 7 , R 10 and R 15 are each independently selected from the group consisting of or 1 to 4 monovalent hydrocarbon radicals or R 17 ; subject to the following relationship that when g=0 then R 7 and R 10 are both R 17 when g is non-zero R 7 and R 10 are each independently selected from the group consisting of 1 to 4 monovalent hydrocarbon radicals; R 15 is R 17 ; R 8 , R 9 , R 11 , R 12 , R 13 , R 14 and R 16 are independently selected from a group consisting of 1 to 4 monovalent hydrocarbon radicals; where the subscripts e, f, g and h are zero or 1 subject to the following relationship: e+f+g+h= 3; with the requirement that when g is 0, then R 7 or R 10 are R 17 ; R 17 is an alkylenoxide group having the formula: R 18 O(C 2 H 4 O) j (C 3 H 6 O) k (C 4 H 8 O) m R 19 where R 18 is a linear or branched hydrocarbon radical having from 2 to 6 carbons, R 19 is selected from the group consisting of H, acetyl or a monovalent hydrocarbon radical of 1 to 6 carbon atoms and the subscripts j, k, and m are zero or a positive integer subject to the limitation that 4<j+k+m≦20; c) an emulsifier comprising an anionic surfactant derived selected from the group consisting of alkylarylsulfonates, alkylsulfonates, alkylsulfates and alkylethersufates, alkyl phosphate esters, alkylaryl phosphate esters, alcoholalkoxylate phosphate esters, and alkylarylalkoxylate phosphate esters and mixtures thereof; and d) the salt of an acidic polymerization catalyst.
