Abstract:
Compositions comprising disiloxane surfactant compositions comprising a silicone composition comprising a silicone having the formula: MM′ where M=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: R8R9R10SiR12 with 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)cR14 where 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 are zero or positive and satisfy the following relationships: 2≦a+b+c≦20 with a≧2, and R5 and R6 are each independently selected from the group of monovalent hydrocarbon radicals having from 1 to 6 carbon atoms or R4 that exhibit resistance to hydrolysis over a wide pH range.
