Biodegradable fabric softener compounds that contain ester linkages a substantial level of polyunsaturation in the hydrophobic chains. The compounds can be used to form fabric softening compositions that are aqueous dispersions of the compounds. These compositions have a desirable low viscosity and recover, after freezing and thawing to have a stable low viscosity.
