Abstract

This invention relates to a cosmetic composition comprising: (A) a film forming composition that can produce a tack free surface comprising: (I) a hydrosilylation reaction product of: (a) a silicone resin having the formula: (R1R22SiO1/2)w(R1R2SiO2/2)x(R2SiO3/2)y(SiO4/2)z wherein R2 is a C1 to C10 hydrocarbon group free of aliphatic unsaturation, R1 is R2 or an alkenyl group, w is from 0.3 to 0.6, x is from 0.0 to 0.2, y is 0, z is from 0.4 to 0.7, w+x+y+z=1.0, and w+z is from 0.85 to 1.0, with the proviso that the silicone resin (a) has at least two silicon-bonded alkenyl groups per number average molecule; (b) a polyether compound having the formula: R3O(C2H4O)c(C3H6O)dR3 wherein R3 is a monovalent unsaturated aliphatic hydrocarbon group containing 2 to 12 carbon atoms, c is from 0 to 50, d is from 0 to 50, and the value of c+d is greater than zero; (c) an SiH functional organopolysiloxane having the general formula: HcR3-cSiO(R2SiO)a(RHSiO)bSiR3-cHc wherein c is 0 or 1, R can be identical or different and is a monovalent, optionally substituted hydrocarbon group with 1 to 18 carbon atoms per molecule, a and b are integers, with the proviso that the sum of a+b is 0 to 300, and wh…
