BLOCK TYPE MODIFIED ORGANOPOLYSILOXANE METHOD OF USING THE ORGANOPOLYSILOXANE COSMETICS AND METHOD OF PRODUCING THE ORGANOPOLYSILOXANE

摘要

An object of the present invention is to provide an organopolysiloxane which is excellent in emulsification stability and aging stability, gives a light touch, has no stickiness, and can provide a cosmetic with good cosmetic persistence. A block organopolysiloxane represented by the following average composition formula (1). (Wherein, in the average composition formula (1), R ¹ is independently a monovalent hydrocarbon group having 1 to 12 carbon atoms, and R ² is a hydrogen atom, a monovalent hydrocarbon group having 1 to 15 carbon atoms, or a monovalent hydrocarbon group having 2 to 7 carbon atoms And R ³ is a hydrogen atom or a monovalent hydrocarbon group having 1 to 4 carbon atoms, X is a divalent hydrocarbon group having 2 to 15 carbon atoms, n is an integer of 1 or more, m is an integer of 1 or more , s is an integer of 0 to 100, t is an integer of 0 to 50, z is an integer of 0 to 50, and R ⁴ each independently represents a hydrogen atom, a hydroxyl group, an alkoxy group, Therefore,
