It was found that it occurred. The cause of this is that even if the silicone is dispersed and stabilized in an aqueous ethanol solution immediately after preparation, it may be gradually separated over time, and this tendency is particularly strong under high temperature storage conditions. It becomes difficult to suppress separation and maintain storage stability at high temperatures.

  The present inventors include (B) a polyvalent acid or a salt thereof, (C) a specific cationic polymer compound or an amphoteric high molecular weight compound in a cosmetic composition containing (A) amino-modified silicone, ethanol and water.
