Abstract (en)
Stable aqueous dispersions are described which display a fabric softening action and contain a biodegradable cationic nitrogen compound. The anion of the compound is the anion of a water-soluble organic Bronstedt acid. The acid is present in an amount more than equivalent to the amount of the nitrogen compound. The cationic nitrogen is obtained from an amine which is prepared from an unsaturated dicarboxylic ester e.g. ditallow maleate and an amine e.g. dimethyl amine.
