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.
L'invention porte sur des composés à base d'un agent d'assouplissement biodégradable, lesquels composés possèdent des liaisons ester sensiblement polyinsaturés dans les chaînes hydrophobes. On peut utiliser ces composés pour produire des compositions assouplissantes consistant en des dispersions aqueuses desdits composés ou en des compositions claires. Ces compositions, qui sont d'une faible viscosité, ont un bon indice de récupération après congélation et décongélation, retrouvant alors, et de manière stable, leur faible indice de viscosité.
