摘要:
This invention relates to a silicone polymer which is insoluble in organic solvents because it has a three-dimensional crosslinked structure which swells up relative to fluorosilicone oils, to a paste-like composition formed by making the silicone compounds swell up in silicone oil, and to a cosmetic material. It is therefore an object of this invention to provide a silicone polymer having a fluorine modified oil with excellent water repellence and oil repellence as base oil, and which swells up relative to these oils, to a homogeneous paste-like composition using this silicone polymer, and to a cosmetic material comprising this composition. This invention is a silicone polymer having a three-dimensional crosslinked structure obtained by polymerizing at least one of an organohydrogen polysiloxane (A1) represented by the general formula (A1): R1aR2bHcSiO(4-a-b-c-)/2nullnull(A1) at least one of a polyoxyalkylene (B1) represented by the following general formula (B1): CfH2f-1O(CgH2gO)hCfH2f-1nullnull(B1) and an organopolyoxyalkylene (B4) represented by the following general formula (B4): R1jR5kSiO(4-j-k)/2nullnull(B4) this polymer being insoluble in organic solvents, and which can contain its own weight or more of pentane-3,3,3-trifluoropropyl pentamethylcyclopentasiloxane. This invention is also a paste-like silicone composition, which is represented by the general formula (C): R1mSiO(4-m)/2nullnull(C) and which is obtained by kneading a mixture of 100 weight parts of the above silicone polymer with 10-1000 weight parts of a fluorine-modified silicone oil having a viscosity at 25 degree C. of 200 mm2/s.
