Abstract
A clear, water-soluble fabric softening composition has been developed from a blend of a quaternary ammonium salt and an amido imidazolinium compound dissolved in water. The former may be an hydrogenated tallow 2-ethylhexyl ammonium methosulfate and the latter a methyl-1-alkyl-amidoethyl-2-alkylimidazolinium methyl sulfate. The composition preferably also contains a lower alkylene glycol, e.g. hexylene glycol for product clarity and has a pH of about to about 4 to about 8.
Claims16
A clear, water-soluble fabric softening composition consisting essentially of:
- (A) about 3 to about 90% by weight of a blend of:
- (1) a quaternary ammonium salt having the structure:
- ##STR4## wherein R is the radical residuum of a mixture of saturated and unsaturated fatty acids having about 12 to about 18 carbon atoms, R' is an alkyl radical having about 2 to about 12 carbon atoms, and X is a halide radical or --SO.sub.3 CH.sub.3 ;
- with
- (2) an amido imidazolinium compound of the structure:
- ##STR5## wherein R.sub.1 and R.sub.2 are each mixtures of the radical residua of saturated and unsaturated fatty acids having about 12 to about 18 carbon atoms, wherein the ratio of component (1) to component (2) is from abut 8:1 to about 3.6:1;
- and
- (B) water.
