Abstract

The present invention relates generally to methods of making surfactant compositions and detergent compositions.

Claims

1. A composition comprising from about 30% to about 70% by weight of anionic surfactant, from about 0.5% to about 25% by weight of a solvent comprising an ethoxylated glycerine of formula (I)

2. A composition according to claim 1 wherein said ethoxylated glycerine has a distribution wherein less than about 10%, preferably less than about 1%, by weight of the ethoxylated glycerine are ethoxylated glycerine molecules of formula (I) having a+b+c<

2.

3. A composition according to claim 1 wherein said composition is substantially free of alkoxylated glycerine ester.

4. A composition according to claim 1 wherein said solvent further comprises glycerine, propoxylated glycerine, ethanol, propylene glycol, diethylene glycol, dipropylene glycol, or mixtures thereof.

5. A composition according to claim 1 wherein said anionic surfactant is selected from the group consisting of linear or branched alkyl benzene sulfonates, linear or branched alkoxylated alkyl sulfates, linear or branched alkyl sulfates, and mixtures thereof.

6. A composition according to claim 1 wherein said composition comprises from about 30% to about 70% by weight of linear or branched alkoxylated alkyl sulfates.

7. A composition according to claim 1 wherein said composition comprises from about 30% to about 60% by weight of linear or branched alkyl sulfates, linear or branched alkyl benzene sulfonates, or mixtures thereof.

8. A composition according claim 1 wherein said composition comprises from about 30% to about 60% by weight of 2-alkyl branched primary alkyl sulfates.

9. A detergent composition comprising from about 10% to about 50% anionic surfactant, from about 0.5% to about 25% by weight of a solvent comprising an ethoxylated glycerine of formula (I)

10. The detergent composition according to claim 9 wherein said adjunct is selected from the group consisting of a structurant, a builder, an organic polymeric compound, an enzyme, an enzyme stabilizer, a bleach system, a brightener, a hueing agent, a chelating agent, a suds suppressor, a conditioning agent, a humectant, a perfume, a perfume microcapsule, a filler or carrier, an alkalinity system, a pH control system, a buffer, an alkanolamine, and mixtures thereof.

11. The detergent composition according to claim 9, wherein said detergent composition comprises an enzyme selected from the group consisting of lipase, amylase, protease, mannanase, cellulase, pectinase, and mixtures thereof.

12. The detergent composition according to claim 9, wherein said detergent composition comprises from about 0.001% to about 1% by weight of enzyme.

13. The detergent composition according to claim 9, wherein said detergent composition is a form selected from the group consisting of a liquid laundry detergent, a gel detergent, a single-phase or multi-phase unit dose detergent, a detergent contained in a single-phase or multi-phase or multi-compartment water-soluble pouch, a liquid hand dishwashing composition, a laundry pretreat product, a fabric softener composition, and mixtures thereof.

14. The detergent composition according to claim 9 wherein said solvent further comprises glycerine, propoxylated glycerine, ethanol, propylene glycol, diethylene glycol, dipropylene glycol, or mixtures thereof.

15. The detergent composition according to claim 9 wherein said composition is substantially free of alkoxylated glycerine ester.

16. The detergent composition according to claim 9 wherein said detergent composition comprises less than about 20%, by weight of the composition, water.

17. The detergent composition according to claim 13 wherein said detergent composition is a detergent contained in a single-phase or multi-phase or multi-compartment water-soluble pouch.
