Abstract

Sulfo-estolides and methods of making them are described. Useful methods include acid side bleaching, partial hydrogenation of the fatty acid, pretreatment of the fatty acid to provide color inhibition, acid side hydrolysis of the sulfo-estolides, or conversion of SHP to an essentially fully hydrolyzed product (HSHP) or a partially hydrolyzed product (PHSHP). Formulations and concentrated formulations of automatic dishwasher detergent or machine wash detergent compositions containing sulfo-estolides, among others, are also included.
