1. A rinse-added liquid fabric softening composition comprising:
- (A) from about 0.5% to about 80% of biodegradable cationic fabric softening compound;
(B) from about 0.01% to about 10% of an enduring perfume which has at least about 70% of components with a ClogP≧
3.0 and a boiling point of≧
250°
C., ClogP being the calculated octanol/water partitioning coefficient (P) expressed as the logarithm to the base 10, logP;
(C) optionally, from about 0% to about 30% of dispersibility modifier; and
(D) the balance comprising a 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;
and wherein the dispersibility modifier affects the viscosity of said liquid fabric softening composition.

Abstract
The present invention relates to liquid and solid biodegradable fabric softener compositions combined with highly enduring substantive perfumes. These compositions are naturally, or synthetically, derived perfumes which are hydrophobic, defined by having a low rinse water solubility (ClogP is greater than or equal to 3.0). These perfumes also have low volatility, a boiling point of 250° C., or greater. These compositions provide better perfume deposition on treated fabric, and consequently are not substantially lost during the rinse and drying cycle for less impact on the environment. Also, these perfumes improve the physical stability of the softener composition.
