where R11 represents a C1-10 divalent hydrocarbon group, R12 represents a C1-4 divalent hydrocarbon group, and q represents a number from 0 to 10; OCN—R20—NCO (B) where R20 represents a C1-20 divalent hydrocarbon group; where R30 represents a C1-10 divalent hydrocarbon group or oxygen atom, and y represents a number 0 or 1; however, when R30 is a C1-10 divalent hydrocarbon group, y represents the number 1, and when R30 is an oxygen atom, y represents the number 0; where each of R40 and R41 independently represent a hydrogen atom or a C1-30 hydrocarbon group optionally having one or two or more substituents selected from the group consisting of a nitro group, an ether group, an ester group and an amide group; however, R40 and R41 may not both be hydrogen atoms; R50—OH (E) where R50 represents a C1-30 hydrocarbon group optionally having one or two or more substituents selected from the group consisting of a nitro group, an ether group, an ester group and an amide group, wherein the polyurethane polyurea is obtained by first manufacturing the polyurethane polyurea prepolymer using each starting material such that the amount of isocyanate groups in the diisocyanate compound starting material is 1.1 to 3.0 moles and the total amount of either or both of amino groups and water, when R30 is oxygen, in the at least one compound of Formula (C) is 0.01 to 1.0 moles per mole of hydroxyl groups in the silicone derivative starting material, and then reacting the polyurethane polyurea prepolymer with the compound selected from the group consisting of the nitrogen compound, the hydroxyl-group containing compound, and combinations thereof such that the total amount of either or both of amino groups in the nitrogen compound and hydroxyl groups in the hydroxyl group-containing compound is 0.05 to 4.0 moles per mole of the hydroxyl groups in the silicone derivative starting material. ### Claim 2 (depends on 1) A silicone oil composition containing 0.1 to 20 parts by mass of the polyurethane polyurea according to claim 1 per 100 parts by mass of a silicone oil. ### Claim 3 (depends on 2) A cosmetic composition containing the silicone oil composition according to claim 2. ### Claim 4 (depends on 1) An ester oil composition containing 0.1 to 20 parts by mass of the polyurethane polyurea according to claim 1 per 100 parts by mass of an ester oil. ### Claim 5 (depends on 4) A cosmetic composition containing the ester oil composition according to claim 4.
