Abstract

Compositions comprising sulfo-estolides and alkyl ester sulfonates are described. Detergent formulations, such as laundry detergents, softeners, and other materials, containing any of these materials are disclosed, as well as personal care formulations, hard surface cleaner formulations, and automatic dishwasher detergent formulations. Laundry methods employing these formulations are also disclosed. These formulations are useful as laundry detergents and can be biodegradable, heavy duty liquids, 2× or 3× and up to 6× concentrates, low foaming, and/or effective in a high efficiency washing machine. Methods for laundering fabrics with the compositions are also disclosed.
