This invention relates to a powder which is surface-treated by a novel silicone compound, and to a makeup containing this powder. In particular, it relates to a silicone compound which has good compatibility with oils such as ester oils and triglycerides or silicone oils, and to a makeup with a smooth feel, excellent dispersibility and excellent emulsification stability. <H0> ÄCompositionÜ </H0> A silicone compound represented by the general formula (1): R<1> aR<2> bR<3> cSiO(4-a-b-c)/2 (in the formula, R<1> is at least one organic group chosen from alkyl having 1-30 carbon atoms, aryl, aralkyl, fluorine-substituted alkyl or organopolysiloxanylsilyl, R<2> is a reactive substituent group chosen from hydrogen, hydroxy or alkoxy having 1-6 carbon atoms, or a reactive substituent group in which at least one of carbon, oxygen and silicon are bonded to these reactive substituent groups, R<3> is a carboxylate residue represented by the following general formula (2): R<4>CO2-Q- R<4> is a saturated or unsaturated hydrocarbon group having 2-30 carbon atoms, Q is a bivalent hydrocarbon group which may also contain a hetero atom, a is 1.0-2.5. b is 0.001-1.5, and c is 0.001-1.5, a powder surface-treated with this silicone compound, and a makeup containing this powder.
