Abstract
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 or clear compositions. These compositions have a desirable low viscosity and recover, after freezing and thawing to have a stable low viscosity.
