ABSTRACT:
A silicone polymer, a paste-like silicone composition prepared by kneading the silicone polymer and a silicone oil under a shearing force, and a water-in-oil type cosmetic composition comprising the paste-like silicone composition as an oil phase component are disclosed. The silicone polymer is prepared by the addition polymerization of components comprising an organohydrogenpolysiloxane R.sup.1.sub.a R.sup.2.sub.b H.sub.c SiO.sub.(4-a-b-c)/2 (1) or R.sup.1.sub.f H.sub.g SiO.sub.(4-f-g)/2 (2) and a polyoxyalkylene C.sub.m H.sub.2m-1 O(C.sub.2 H.sub.4 O).sub.h (C.sub.3 H.sub.6 O).sub.i C.sub.m H.sub.2m-l (A) or an organopolysiloxane R.sup.1.sub.j R.sup.4.sub.k SiO.sub.(4-j-k)/2 (B) the components, including (1) or (A) as an essential component. The silicone polymer can swell in silicone oils and function as a viscosity increasing agent for silicone oils.
