Abstract
An aqueous concentrated cationic fabric softening composition wherein the cationic softener system comprises a binary mixture of a mono nitrogen quaternary ammonium cationic softener salt and a second cationic softener salt selected from certain di(2-amidoethyl)methyl quaternary ammonium salts and imidazolinium salts.
Claims14
Concentrated aqueous fabric softener compositions which are pourable at 40.degree. F., the said compositions comprising:
- A. from 8% to about 12.5% of a mono nitrogen quaternary ammonium cationic softener salt having the formula ##STR10## 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 or --(C.sub.n H.sub.2n O).sub.x H groups wherein n is 2 or 3, x is from 1 to about 3, and wherein X.sup.- is an anion selected from halide, methylsulfate or ethylsulfate;
- B. from about 5% to about 18% of a second cationic softener salt selected from the group consisting of ##STR11## 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 or methylsulfate;
- ##STR12## 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;
- ##STR13## 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;
- C. from about 0.05% to 0.6% of an inorganic water-soluble ionizable salt;
- and
- D. water;
- wherein the total amount of Components A+B is from about 15% to about 23%, wherein there is unsaturation present on at least one of Components A or B such that the cationic active system has an Iodine Value of at least about 5.7.
