Compound in which polyglycerol, fatty acid, and dicarboxylic acid have been esterified

An oily cosmetic comprising

• a compound which is an ester of a polyglycerol, a fatty acid and a dicarboxylic acid, wherein the compound satisfies the following (A) to (D):
• (A) an average degree of polymerization of the polyglycerol is from 2 to 20;
• (B) among the total fatty acid, a total proportion of an unsaturated fatty acid and a branched fatty acid having 18 to 22 carbon atoms is 70% by mass or more;
• (C) a mass ratio of the polyglycerol to the fatty acid (polyglycerol:fatty acid) is from 1:0.78 to 1:1.5;
• and
• (D) the number of carbon atoms of the dicarboxylic acid is from 4 to 12, and a molar ratio to the polyglycerol (dicarboxylic acid/polyglycerol) is from 0.01 to 0.30;
• and
• an oil agent,
• wherein a content of the oil agent in the oily cosmetic is from 35 to 99% by mass, and
• wherein the dicarboxylic acid is selected from the group consisting of maleic acid, adipic acid, sebacic acid, and dodecanedioic acid.
