| 摘要 |
The present invention is an organopolysiloxane shown by the following average composition formula (1), wherein each of R1 independently represents a monovalent hydrocarbon group having 1 to 12 carbon atoms; R2 represents any of a hydrogen atom, a monovalent hydrocarbon group having 1 to 15 carbon atoms, and a monovalent acyl group having 1 to 6 carbon atoms; "n" represents an integer of 0 to 1000; "m" represents 2 or 3; "X" represents a divalent hydrocarbon group having 2 to 15 carbon atoms; Y represents C-CH2-CH3 when "m" represents 2, while representing a carbon atom when "m" represents 3; "s" represents an integer of 0 to 100; "t" represents an integer of 0 to 50; and "z" represents an integer of 0 to 50. Organopolysiloxane gives a cosmetic with excellent emulsion stability, temporal stability, and cosmetic durability, and excellent dispersion properties to powders.
