Abstract
Concentrated fabric softening/static control compositions, for use in the rinse cycle of the laundering operation, are disclosed. These compositions include a water-insoluble cationic softener, a long-chain hydrocarbon, such as paraffin, and specific mono-long chain amine or amine-derived compounds. The use of these amine compounds provides compositions, exhibiting excellent softening and static control performance, which are stable during long periods of storage and which are easily processed due to their viscosity characteristics. A method for preparing these compositions is also disclosed.

An aqueous textile treatment composition exhibiting viscosities of no more than about 700 centipoise over the temperature range of 25.degree. C. to 65.degree. C., said composition comprising
- (a) from about 8% to about 16% of water-insoluble cationic fabric softener selected from the group consisting of (i) compounds of the general formula R.sup.a R.sup.b R.sup.c R.sup.d N.sup.+ X.sup.- wherein R.sup.a and R.sup.b are each selected from C.sub.12 -C.sub.24 alkyl groups, R.sup.c and R.sup.d are each selected from C.sub.1 -C.sub.4 alkyl groups and X is an anion, (ii) Di-C.sub.12 -C.sub.24 alkyl imidazolinium salts, and (iii) mixtures thereof;
- (b) from about 5% to about 20% of C.sub.14 -C.sub.22 hydrocarbon;
- (c) from about 0.15% to about 0.7% of an amine-derived compound having the formula ##STR8## wherein R.sup.1 and R.sup.2 are each selected from methyl or ethyl groups, n is 2 or 3, and R.sup.3 is a C.sub.16 -C.sub.18 alkyl group;
- wherein the weight ratio of (a):(b) is from about 3:1 to 1:2.
