摘要
(EP3699183) The present invention is a urea group-containing organopolysiloxane represented by the following formula (1),wherein, R1is -R5-NHCONH2(R5is a divalent hydrocarbon group), R2is any of a hydrogen atom, a hydroxy group, an alkoxy group, an alkyl group, a fluoroalkyl group, an aryl group, and an aralkyl group, R3is R1or R2, and R4is an organopolysiloxane segment represented by the following formula (2),(Q is an oxygen atom or a divalent hydrocarbon group), the urea group-containing organopolysiloxane represented by the formula (1) has one or more R1in the molecule, when "c" is 0, "a" + "d" + "f" + "h" + "i" is 1 or more.Accordingly, there is provided a urea group-containing organopolysiloxane that can obtain a cosmetic having excellent cosmetic durability while maintaining a light feel and good spreadability, and a method for manufacturing the same, as well as a cosmetic containing the same.

(EP3699183) 1. A urea group-containing organopolysiloxane represented by the following average composition formula (1) ,in the formula (1), R1 is -R5-NHCONH2 (R5 is a divalent hydrocarbon group having 2 to 10 carbon atoms), R2s are each independently any of a hydrogen atom, a hydroxy group, an alkoxy group having 1 to 3 carbon atoms, an alkyl group having 1 to 30 carbon atoms, a fluoroalkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 30 carbon atoms, and an aralkyl group having 7 to 30 carbon atoms, R3 is R1 or R2, and R4 is an organopolysiloxane segment represented by the following average composition formula (2),in the formula (2), R1 and R2 are as described above, and Q is an oxygen atom or a divalent hydrocarbon group having 1 to 3 carbon atoms,  in the average composition formula (1) and the general formula (2), "a", "f" and "i" are each independently 0 to 3, "b" is 0 to 5000, "c" is 0 to 500, "d" is 0 to 100, "e" is 0 to 100, "g" is 0 to 5000, and "h" is 0 to 500; provided that, the urea group-containing organopolysiloxane represented by the formula (1) has one or more R1 in the molecule, when "c" is 0, "a" + "d" + "f" + "h" + "i" is 1 or more. 2. A method for manufacturing the urea group-containing organopolysiloxane according to claim 1 comprising:  subjecting to addition reaction of an organohydrogenpolysiloxane and an unsaturated group-containing urea compound. 3. The method for manufacturing the urea group-containing organopolysiloxane according to claim 2, wherein the unsaturated group-containing urea compound is allyl urea. 4. A method for manufacturing the urea group-containing organopolysiloxane according to claim 1 comprising:  subjecting to reaction of an amino group-containing organopolysiloxane and urea. 5. A cosmetic comprising the urea group-containing organopolysiloxane according to claim 1. 6. The cosmetic according to claim 5, further comprising water and being in a form of an emulsion system of a water-in-oil emulsion or an oil-in-water emulsion. 7. The cosmetic according to claim 5 or claim 6, further comprising powder. 8. The cosmetic according to any one of claim 5 to claim 7, wherein the cosmetic is a skin care cosmetic, a makeup cosmetic, a hair cosmetic, an antiperspirant cosmetic, or an ultraviolet protection cosmetic.
