1. A method for making a cosmetic composition comprising preparing a cosmetic composition comprising the reaction product of:

  • MaMHbMEcDdDHeDEfTgTHhTEiQj where M=R1R2R3SiO1/2;

    MH=R4R5HSiO1/2;

    ME=R6R7RESiO1/2;

    D=R8R9SiO2/2;

    DH=R10HSiO2/2;

    DE=R11RESiO2/2;

    T=R12SiO3/2;

    TH=HSiO3/2;

    TE=RESiO3/2; and

    Q=SiO4/2;

    where R1, R2, R3, R8, R9 and R12 are independently monovalent hydrocarbon radicals having from one to sixty carbon atoms;

    R4, R5 and R10 are independently monovalent hydrocarbon radicals having from one to sixty carbon atoms or hydrogen;

    R6, R7, R11 are independently monovalent hydrocarbon radicals having from one to sixty carbon atoms or RE;

    each RE is independently a monovalent hydrocarbon radical containing one or more oxirane moieties having from one to sixty carbon atoms;

    the stoichiometric subscripts a, b, c, d, e, f, g, h, i, and j are either zero or positive subject to the following limitations;

    a+b+c>

    1;

    b+e+h>

    1;

    c+f+i>

    1;

    b+e+h>

    c+f+i; and

    when d+e+f+g+h+i+j=0, a+b+c=2.
