COSMETIC

摘要

A cosmetic containing a hydrophilic thickening agent, wherein the zero shear viscosity (?0), the yield stress (sy) and the yield strain (?y) of an aqueous solution comprising water and the hydrophilic thickening agent at a concentration of 0.5 mass% and having a pH value of 6.8-7.0 fulfill the following requirements (1), (2) and (3) at 25°C: (1) 1×103 Pa·s = ?0 = 1×106 Pa·s; (2) 500 = a = 25000 wherein the relationship between ?0 and sy is represented by the formula -1:?0 = a×sy 2; and (3) 0.1% = ?y = 3%.
