Abstract
Sulfo-estolides and methods of making them are described. Also described are phase-stable compositions formed from mixtures of different salts of sulfo-estolides, particularly mixtures of sodium and potassium salts of sulfo-estolides, and methods of obtaining phase-stable sulfo-estolide mixed salt compositions. The sulfo-estolide mixed salt compositions can be used in detergent formulations, such as laundry detergents, household, industrial and institutional cleaning formulations, and person care products.
