Abstract
Compositions comprising disiloxane surfactant compositions comprising a silicone composition comprising a silicone having the formula:MM′whereM=R1R2R3SiO1/2;M′=R4R5R6SiO1/2;with R1 selected from the group consisting of branched monovalent hydrocarbon radical of from 3 to 6 carbon atoms and R7, where R7 has the formula:R8R9R10SiR12with R8, R9, and R10 each independently selected from the group of monovalent hydrocarbon radicals having from 1 to 6 carbon atoms and monovalent aryl or alkaryl hydrocarbon radicals having from 6 to 13 carbon atoms and R12 is a divalent hydrocarbon radical having from 1 to 3 carbon atoms,R2 and R3 are each independently selected from the group of from 1 to 6 carbon atom monovalent hydrocarbon radicals or R1, with R4 an alkylpolyalkyleneoxide of the general formula:R13(C2H4O)a(C3H6O)b(C4H8O)cR14where R13 is a divalent linear or branched hydrocarbon radical having the structure:—CH2—CH(R15)(R16)dO—where R15 is H or methyl; R16 is a divalent alkyl radical of 1 to 6 carbons where the subscript d may be 0 or 1;R14 is selected from the group consisting of H, monovalent hydrocarbon radicals of from 1 to 6 carbon atoms and acetyl where the subscripts a; b and c a…
