ABSTRACT:
A composition comprising the reaction products ofin-line-formulae description="In-line Formulae" end="lead"?MaMHbMEcDdDHeDEfTgTHhTEiQjin-line-formulae description="In-line Formulae" end="tail"?whereM=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; andQ=SiO4/2;where R1, R2, R3, R8, R9and R12are independently monovalent hydrocarbon radicals having from one to sixty carbon atoms; R4, R5and R10are independently monovalent hydrocarbon radicals having from one to sixty carbon atoms or hydrogen; R6, R7, R11are independently monovalent hydrocarbon radicals having from one to sixty carbon atoms or RE; each REis 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. In a preferred embodiment the reaction product of the present invention is a polyether siloxane copolymer network. In another preferred embodiment embodiment the reaction product of the present invention is a polyether siloxane copolymer network swollen with a volatile low molecular weight silicon containing compound. These compositions are useful for a variety of personal care compositions.
