PERSISTENT COMPOSITION STRUCTURIZED BY POLYMER AND PASTY FATTY MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtain a composition capable of providing a film hardly moved, having an appearance having gloss, and further having good persistency with time. SOLUTION: This structured composition structured by a pasty fatty material and a polymer having 100,000 weight average molecular weight, and containing liquid fatty phase is the one forming a physiologically acceptable medium composed of a liquid fatty phase, a pasty fatty material and the polymer. The polymer comprises (a) a polymer skeleton having a hydrocarbon-based repeating unit having a hetero atom, and (b) a (functionalized) 12-120C pendant fatty chain bonded to the unit and/or a (functionalized) terminal fatty chain, and is regulated so that the number of the fatty chains may cover 40-98% of the total number of the units having the hetero atoms and the fatty chains.
