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.

Claims

1. A light duty liquid detergent composition, comprising:

about 0.1% to about 90% active weight of the total composition of at least one sulfo-estolide surfactant having the following general Formula 1;

2. A laundry detergent composition, comprising:

about 5% to about 99% by weight of at least one compound having the following general Formula 1;

3. A laundry detergent composition, comprising:

about 2% to about 90% by weight of one or more compounds having the following general Formula 1;

4. A green laundry detergent composition, comprising:

about 2% to about 99.9% by weight of one or more compounds having the following general Formula 1;

5. The composition of claim 4, wherein at least one of the compounds of Formula 1 is a potassium salt.

6. A liquid personal care composition, comprising:

about 0.1% to about 99% by weight of at least one surfactant having the following general Formula 1;

7. The personal care composition of claim 6, further comprising at least one additive selected from the group consisting of viscosity modifiers, electrolytes, emollients, skin conditioning agents, emulsifier/suspending agents, fragrances, colors, herbal extracts, vitamins, builders, enzymes, pH adjusters, preservatives, antibacterial agents, antidandruff agents, derivatives thereof, and combinations thereof.

8. The personal care composition of claim 6, wherein the pH value is in the range of about 5 to about 7.

9. The personal care composition of claim 6, wherein the composition is a liquid hand soap.

10. The personal care composition of claim 6, wherein the composition is a body wash.

11. The personal care composition of claim 6, wherein the composition is a facial cleaner.

12. The personal care composition of claim 6, wherein the composition is a shampoo, a 2-in-1 shampoo or an antidandruff shampoo.

13. The personal care composition of claim 6, the composition has a total surfactant concentration of about 20% by weight or more.

14. A low-foaming liquid machine dishwashing detergent composition comprising:

about 0.1% to about 20% by active weight of one or more surfactants of the general Formula 1;

15. A hard surface cleaning composition, comprising:
