Abstract: The invention provides a process for the preparation of a modified triethanolamine/fatty acid ester composition ratio by treatment of a conventional triethanolamine fatty acid ester composition with a hydrolytic enzyme. Also provided are novel mixtures of triethanolamine and mono-, di-, and tri-esters of fatty acids which are useful in the preparation of cationic surfactants useful in fabric softening applications. In one aspect, the method increases the triester fraction without significantly affecting the amount of mono-ester and unesterified species, which in turn adds to the flexibility in the formulation of the corresponding fabric softening compositions.

Abstract: The invention provides a process for the preparation of a modified triethanolamine/fatty acid ester composition ratio by treatment of a conventional tnethanolamine fatty acid ester composition with a hydrolytic enzyme. Also provided are novel mixtures of tnethanolamine and mono-, di-, and tri-esters of fatty acids which are useful in the preparation of cationic surfactants useful in fabric softening applications. In one aspect, the method increases the triester fraction without significantly affecting the amount of mono-ester and unesterified species, which in turn adds to the flexibility in the formulation of the corresponding fabric softening compositions.
