Abstract

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

First claim

What is claimed is:

1. A method of making a concentrated anionic surfactant paste comprising the steps of:
i) mixing 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 alkoxylated glycerine of formula (I)

wherein R is CH 3 or H, a +b +c has an average value of from about 1 to about 60, and water to form a concentrated anionic surfactant paste,
wherein said anionic surfactant paste comprises from about 30% to about 60% by weight of 2-alkyl branched primary alkyl sulfates,
wherein said concentrated anionic surfactant paste is free of alkoxylated glycerine ester;

ii) storing and optionally shipping said concentrated anionic surfactant paste, wherein said concentrated anionic surfactant paste is stable during storage.

2. A method of making a detergent composition comprising the steps of:
i) mixing 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 alkoxylated glycerine of formula (I)

wherein R is CH 3 or H, a +b +c has an average value of from about 1 to about 60, and water to form a concentrated anionic surfactant paste, wherein said anionic surfactant paste comprises from about 30% to about 60% by weight of 2-alkyl branched primary alkyl sulfates;

ii) storing and optionally shipping said concentrated anionic surfactant paste, wherein said concentrated anionic surfactant paste is stable during storage;
iii) mixing said stable concentrated anionic surfactant paste with an adjunct and water to form a detergent composition, wherein said detergent composition is free of alkoxylated glycerin ester.

3. The method according to claim 1 wherein said solvent further comprises glycerine, ethanol, propylene glycol, diethylene glycol, dipropylene glycol, or mixtures thereof.

4. The method according to claim 1 wherein said R groups are identical.

5. The method 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. The method according to claim 1 wherein said concentrated anionic surfactant paste comprises from about 30% to about 70% by weight of linear or branched alkoxylated alkyl sulfates.

7. The method according to claim 1 wherein said concentrated anionic surfactant paste 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. The method according to claim 2 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.

9. The method according to claim 2 wherein said adjunct comprises an enzyme selected from the group consisting of lipase, amylase, protease, mannanase, cellulase, pectinase, and mixtures thereof.

10. The method according to claim 2 wherein said adjunct comprises from about 0.001% to about 1% by weight of enzyme.

11. The method according to claim 2 , 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.

12. The method according to claim 2 , wherein said detergent composition comprises less than about 20%, by weight of the composition, water.

13. The method according to claim 2 , wherein said detergent composition is a detergent contained in a single-phase or multi-phase or multi-compartment water-soluble pouch.
