Abstract
The present invention relates to fabric care and fabric softener compositions which comprise: PA1 a) from about 2% by weight, of a cationic fabric softening active; PA1 b) at least about 0.2% by weight, of a cationic charge boosting system; and PA1 c) the balance carriers and other adjunct ingredients wherein the cationic charge booster system is the admixture which results from the preparation of a acylated di-quaternary ammonium wherein less than full equivalents of reactants are used in at least one step. The resulting admixture of di-amines, acylated diamines, and acylated quaternized diamines provides a superior charge boosting system which allows the use of fabric softening active which normally have insufficient cationic charge character for effective fabric softness activity.
