Abstract
Shelf-stable biodegradable fabric softening compositions are provided comprising mixtures of a quaternized ester-ammonium softening compound having the formula ##STR1## and mixtures thereof, wherein each R substituent is independently selected from C.sub.1 -C.sub.6 alkyl, alkenyl or hydroxyalkyl groups, R.sup.1 is a C.sub.14 -C.sub.22 hydrocarbyl group, R.sup.2 is a C.sub.13 -C.sub.21 hydrocarbyl group, and A.sup.- is a softener compatible anion; and a liquid carrier. These biodegradable compositions have improved product stability and dispersability, as well as excellent fabric softening characteristics.
