ABSTRACT:
Liquid fabric softening compositions for use in a rinse bath after washing fabrics with a detergent. The softening compositions contain (a) the reaction products of higher fatty acids with a polyamine selected from the group consisting of hydroxyalkylalkylenediamines and dialkylenetriamines and mixtures thereof, (b) cationic nitrogenous salts having only one long chain acyclic aliphatic hydrocarbon group, and optionally (c) cationic nitrogenous salts having two or more long chain acyclic aliphatic hydrocarbon groups or one said group and an arylalkyl group; these compositions provide good softening performance across major types of detergents.
