Abstract:
A stable, aqueous, liquid, concentrated fabric softening composition consisting essentially of:(A) biodegradable diester quaternary ammonium fabric softening material selected from the group consisting of: [(R)4âˆ’mâ€”N(+)â€”[(CH2)nâ€”Yâ€”R2]m]X(âˆ’)â€ƒâ€ƒ(1) wherein each R is selected from the group consisting of C1 to C6 alkyl, and C1 to C6 hydroxyalkyl groups; each m is 2 or 3; each n is from 1 to about 4; each R2 is selected from the group consisting of from about C12 to about C22 hydrocarbyl and from about C12 to about C22 substituted hydrocarbyl group such that the IV of the parent fatty acid of this R2 group is less than about 10; each Y is â€”Oâ€”(O)Câ€” or â€”C(O)â€”O, but not OC(O)O; and wherein X(âˆ’) is a compatible anion; and(B) co-active fabric softening material selected from the group consisting of: wherein each Y2 is either: â€”N(R4)C(O)â€”, in which each R4 is selected from the group consisting of C1-C6 alkyl, C1-C6 alkenyl, C1-C6 hydroxyalkyl group, and hydrogen; â€”OC(O)â€”; and a single covalent bond; and wherein each R3 is a hydrocarbon group containing from about 11 to about 31 carbon atoms; and wherein each n2 is independently from 2 to about 4; wherein each R7 is selected from the group consisting of C14 to C20 alkyl and C14 to C20 alkenyl groups; each R8 is selected from the group consisting of methyl, ethyl, and â€”(CmH2mO)n3H; wherein n3 is from 1 to about 5; and wherein each m, and X(âˆ’) are as hereinbefore; which is a diester quaternary ammonium compound formed from a parent fatty acid and triethanolamine wherein each R9 is a C15-C17 fatty alkyl group such that the IV of the parent fatty acid of this R9 group is from about 20 to about 100, and X(âˆ’) is as hereinbefore; which is a diester quaternary ammonium compound formed from a parent fatty acid wherein each R10 is a C12-C22 hydrocarbyl or a C12-C22 substituted hydrocarbyl substituent, such that the IV value of the parent fatty acid of this R10 group is from about 20 to about 100, and R and X(âˆ’) are as hereinbefore; and mixtures thereof.
