摘要:
This invention relates to a makeup containing a specific modified silicone obtained by an economical manufacturing method not requiring an esterification catalyst, having a high reaction rate and therefore leaving little unreacted material, and in particular relates to a makeup with good skin adhesion, good retention and excellent emulsion stability. A silicone compound represented by the general formula (1): R1aR2bSiO(4-a-b)/2 (in the formula, R1 is at least one substituent group having 1-30 carbon atoms, chosen from alkyaryl, aralkyl, fluorine-substituted alkyl or organopolysiloxanylsilyl, R2 is a carboxylate residue represented by the following general formula (2): R3 is a saturated or unsaturated hydrocarbon group having 2-30 carbon atoms, a is 1.0-2.5, and b is 0.001-1.5.
