摘要:
There is provided herein a composition comprising a silicone copolymer of the general formula (I) MaMEcDdDEeTfTEgQh where M=R1R2R3SiO1/2 ME=R4R5RESiO1/2 D=R6R7SiO2/2 DE=R8RESiO2/2 T=R9RESiO2/2 T=R9SiO3/2 TE=RESiO2/2 and Q=SiO4/2 where R1, R2, R3, R4, R5, R6, R7, R8, and R9 are each independently selected from the group of monovalent hydrocarbon radicals RE is a monovalent radical defined as: -R10O-(C2H4O)h(C3H6O)i(C4H8O)i-R11 or -R12 with the provision that the copolymer must contain at least one RE group R10 is a linear or branched divalent hydrocarbon radical containing from 3 to about 10 carbon atoms R11 is H or -C(=O)CH3 or a monovalent saturated or unsaturated hydrocarbon radical, optionally containing heteroatoms and hydroxyl groups, containing from 1 to about 30 carbon atoms R12 is a hydrocarbon radical, containing from 2 to about 30 carbon atoms and at least 1 hydroxyl group, optionally containing heteroatoms subscripts a, b, c, d, e, f, and g are 0 or positive subject to the limitation a+b+c+d+e+f+g<1000 subscripts h, i, and j are 0 or positive subject to the limitation h+i+j is less than 100 and, b) an organic oil.
