Abstract

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 R¹ a R² b H c SiO (4-a-b-c)/2 (1) or R¹ f H g SiO (4-f-g)/2 (2) and a polyoxyalkylene C m H 2m-1 O(C₂H₄O) h (C₃H₆O) i C m H 2m-1 (A) or an organopolysiloxane R¹ j R⁴ k SiO (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.
