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.
