1. A rinse-added rinse cycle fabric softening composition selected from the group consisting of:
- I. a solid particulate composition comprising;
(A) from about 50% to about 95% of biodegradable cationic quaternary ammonium fabric softening compound;
(B) from 0.01% to about 15% by weight of the composition, of a diester having the formula R1 R'"'"'R2 wherein R'"'"' is a residue of an acid forming diester selected from the group consisting of succinic acid or maleic acid; and
wherein R1 and R2 independently represent a residue of an alcohol forming diester selected from the group consisting of phenoxanol, floralol, B-citronellol, nonadyl, cyclohexyl ethanol, phenyl ethanol, isoborneol, fenchol, isocyclogeraniol, 2-phenyl-1-propanol, 3,7-dimethyl-1-octanol and mixtures thereof;
(C) optionally, from about 0 to about 30% of dipsersibility modifier; and
(D) optionally, from about 0% to about 15% of pH modifier; and
II. a liquid composition comprising;
(A) from about 0.5% to about 80% of biodegrable cationic quaternary ammonium fabric softening compound;
(B) from 0.01% to about 15% by weight of the composition, of a diester having the formula R1 R'"'"'R2 wherein R'"'"' is a residue of an acid forming diester selected from the group consisting of succinic acid or maleic acid; and
wherein R1 and R2 independently represent a residue of an alcohol forming diester selected from the group consisting of phenoxanol, floralol, B-citronellol, nonadyl, cyclohexyl ethanol, phenyl ethanol, isoborneol, fenchol, isocyclogeraniol, 2-phenyl-1-propanol, 3,7-dimethyl-1-octanol and mixtures thereof;
(C) optionally, from about 0 to about 30% of dipsersibility modifier; and
(D) the balance comprising liquid carrier selected from the group consisting of water, C1-4 monohydric alcohol, C2-6 polyhydric alcohol, propylene carbonate, liquid polyethylene glycols and mixtures thereof.
