Abstract
Emulsion compositions, suitable for personal care applications such as hair styling, and other applications, are disclosed. The compositions comprise: PA0 a) a silicone functional polymer having the formula selected from the group consisting of: PA1 (AB).sub.n ; ABA; BAB; ##STR1## and mixtures thereof; wherein B is a silicone moiety comprising repeating units of: ##STR2## R is independently, C1-C30 alkyl, aryl, alkylaryl, haloalkyl, H, or C1-C6 alkoxy, wherein the weight average molecular weight of each silicone moiety B is independently from about 1500 to about 50,000; PA1 A is a polar polymeric moiety which is soluble or dispersible in mixtures of ethanol and water containing less than 60% ethanol by weight; and PA1 n is an integer of 1 or greater; wherein the molecular weight of the silicone functional polymer is at least about 2,000. PA0 b) an organopolysiloxane emulsion comprising: PA1 (i) a polyorganosiloxane dispersed as particles in the emulsion, the polyorganosiloxane having an average particle size of less than about 150 nanometers, and PA1 (ii) a surfactant system for dispersing the organopolysiloxane in the emulsion; PA0 c) a carrier comprising at least about 0.5%, by w…
