Abstract

A wash cycle fabric softener composition which is dispersible in the wash water of a laundering operation including handwash. The fabric softener composition comprises, by weight:(a) from about 48% to about 82% of at least one amine fabric softening active compound;(b) from about 0.1% to about 18% of an alpha hydroxy aliphatic acid selected from the group consisting of citric acid, lactic acid, glycolic acid and mixtures thereof, wherein the amine fabric softening active compound at least partially reacts in situ with the alpha hydroxy acid to form an amine salt of the alpha hydroxy acid;(c) from about 0.5% to about 6% of a cationic surfactant;(d) from about 0% to about 9% of a cationic softener;(e) from about 4% to about 14% of a perfume; and(f) less than about 6% of water.
