<P>PROBLEM TO BE SOLVED: To provide a dispersant having a high dispersing effect by addition of its small amount, a cosmetic improved in feel of use, a sunscreen reduced in powdery finish during application, and a cosmetic which causes less color unevenness of an inorganic pigment, since the inorganic powder has a high specific gravity, and causes problems of agglomeration of powder, etc., so it is difficult to stably disperse inorganic powder in an oil agent, and an oil-based dispersant for stably dispersing inorganic powder by addition of its small amount has been desired. <P>SOLUTION: The cosmetic includes an oil-based dispersant containing a polyglycerol having an average polymerization degree of 30 to 100, and a ratio of the cyclic groups in the polyglycerol of 30% or less, and a polyglycerol branched fatty acid ester having an HLB of 1.0 to 6.0 produced by esterifying a 8 to 22C branched fatty acid. <P>COPYRIGHT: (C)2013,JPO&INPIT |
