Title: POLYURETHANE GEL COMPOSITION AND USE THEREOF
Abstract:
A polyurethane gel composition is provided that contains A and B described below. Here, A is either a polyurethane obtained by a reaction between (a) a hydrogenated polybutadiene having an isocyanate group at the terminal and (b) a glycol represented by HO-R3-OH (in the expression, R3 represents a linear or branched C2-C6 alkylene group optionally having an ether bond), or, A is a polyurethane obtained by a reaction between (c) a hydrogenated polybutadiene having a hydroxyl group at the terminal, (d) a diisocyanate compound, and (b) a glycol represented by HO-R3-OH (in the expression, R3 represents a linear or branched C2-C6 alkylene group optionally having an ether bond), and B is an oil solution. A membrane of an oil soluble gel obtained from said polyurethane gel composition has extremely excellent transparency, high gloss, elasticity and resilience, so this polyurethane gel composition is particularly useful as a raw material of a cosmetic.
