ABSTRACT:
Stable easily pourable aqueous fabric softening compositions based on all natural ingredients, including lecithin as the fabric softening agent and sorbic acid as preservative and saponin as emulsifier are provided. The softening component comprises from about 2 to 20% by weight of the composition. Sorbic acid and saponin are present in amounts of 0.1 to 5% and 0.1 to 2%, respectively. The compositions are stable at pH's ranging from 4.5 to 5 and higher. Methods for making the composition are also described. Softening performance is comparable to that obtained by using quaternary ammonium compound softeners. The softener compositions are primarily intended for use in the rinse cycle of an automatic washing machine.
