PROBLEM TO BE SOLVED: To provide a specific modified silicone which can be obtained by an economical production method which does not require an esterification catalyst, has a high reaction rate, and therefore has few unreacted substances, and a cosmetic containing the silicone. In particular, the present invention relates to a cosmetic that has good adhesion to the skin, has good cosmetic durability, and is excellent in emulsifying properties. SOLUTION: The general formula (Formula 1) (Wherein R 1 has 1 to 1 carbon atoms) 30 is at least one substituent selected from the group consisting of 30 alkyl groups, aryl groups, aralkyl groups, fluorine-substituted alkyl groups, and organopolysiloxanylsilylalkyl groups; and R 2 has the following general formula (Chemical Formula 2) Wherein R 3 is a saturated or unsaturated hydrocarbon group having 2 to 30 carbon atoms, a is 1.0 to 2.5, and b is 0.001 to 1 .5. ). |
