Abstract
An aqueous concentrated cationic fabric softening composition wherein the cationic softener system comprises a mixture of a mono nitrogen quaternary ammonium salt, a di(2-amidoethyl)methyl quaternary ammonium salt and an imidazolinium salt, the said cationic system having an Iodine Value of at least 4.2.
Claims19
A concentrated homogeneous aqueous fabric softener composition which is pourable at 40.degree. F., the said composition comprising:
- A. from about 2% to about 11% of a quaternary ammonium salt having the formula ##STR15## wherein R.sub.1 and R.sub.2 can be the same or different from each other and are selected from the group consisting of C.sub.14 to C.sub.20 alkyl and alkenyl groups, R.sub.3 and R.sub.4 can be the same or different and are selected from the group consisting of C.sub.1 to C.sub.3 alkyl and --(C.sub.n H.sub.2n O).sub.x H groups wherein n is 2 or 3, x is from about 1 to about 3, and wherein X.sup.- is an anion selected from halide, methylsulfate and ethylsulfate;
- B. from about 2% to about 14% of a di(2-amidoethyl) methyl quaternary ammonium salt having the formula ##STR16## wherein R.sub.5 and R.sub.6 are the same or different from each other and are selected from the group consisting of C.sub.14 to C.sub.20 alkyl and alkenyl groups, wherein R.sub.7 is selected from the group consisting of H, methyl, ethyl and (C.sub.n H.sub.2n O).sub.x H wherein n is 2 or 3 and x is from 1 to about 5 and wherein X.sup.- is selected from halide, ethylsulfate and methylsulfate;
- C. from about 2% to about 13% of an imidazolinium quaternary salt having the formulas ##STR17## wherein R.sub.8 and R.sub.9 are the same or different from each other and are selected from the group consisting of C.sub.14 to C.sub.20 alkyl and alkenyl groups, wherein X.sup.- is halide, ethylsulfate or methylsulfate;
- ##STR18## wherein R.sub.10 and R.sub.11 can be the same or different from each other and are selected from the group consisting of C.sub.14 to C.sub.20 alkyl and alkenyl and X.sup.- is halide, methylsulfate or ethylsulfate;
- and ##STR19## wherein R.sub.12, R.sub.13, and R.sub.14 are the same or different from each other and are selected from the group consisting of C.sub.14 to C.sub.20 alkyl or alkenyl, wherein X.sup.- is halide, methylsulfate or ethylsulfate;
- D. from about 0.05% to 0.6% of an inorganic water-soluble ionizable salt;
- and
- E. water;
- wherein the total amount of Components A+B+C is from about 15% to about 22.5%, wherein there is unsaturation present on at least one of Components A, B or C such that the cationic active system, components A+B+C, has an Iodine Value of at least about 4.2.
