Abstract

Abstract The liquid softener composition is useful for the housework, improved in softening and rinsing and comprises (a) 10 to 30 percent by weight of a neutralized product of an inorganic or organic acid with an ester amine having the formula (I) or (IIV), having an average size of 0.1 to 5 microns in the dispersed state, (b) 0.2 to 10 percent by weight of an inorganic electrolyte and the balance of water. in which R1 and R2 each are a hydrocarbon group having 11 to 23 carbon atoms, straight or branched, saturated or unsaturated, R is a hydrocarbon group having 1 to 24 carbon atoms, straight or branched, saturated or unsaturated, hydroxyethyl, hydroxypropyl, R10 is a hydrocarbon group having 8 to 24 carbon atoms, straight or branched, saturated or unsaturated, and m is 2 or 3.
