Abstract

The present invention relates generally to detergent compositions and, more specifically, to detergent compositions containing a branched surfactant.

First claim

What is claimed is:

1. A detergent composition comprising from about 0.1% to about 99% by weight of the composition of a first surfactant, wherein said first surfactant consists essentially of a mixture of surfactant isomers of Formula I and surfactants of Formula II:

wherein from about 50% to about 100% by weight of the first surfactant are isomers having m+n=11; wherein from about 0.001% to about 25% by weight of the first surfactant are surfactants of Formula II; and wherein X is a hydrophilic moiety.

2. A detergent composition according to claim 1 wherein from about 0.5% to about 30% by weight of the first surfactant are isomers having m+n=10, from about 1% to about 45% by weight of the first surfactant are isomers having m+n=12, and from about 0.1% to about 20% by weight of the first surfactant are isomers having m+n=13.

3. A detergent composition according to claim 1 wherein from about 55% to about 75% by weight of the first surfactant are isomers having m+n=11, wherein from about 0.5% to about 30% by weight of the first surfactant are isomers having m+n=10; wherein from about 15% to about 45% by weight of the first surfactant are isomers having m+n=12, wherein from about 0.1% to about 20% by weight of the first surfactant are isomers having m+n=13, and wherein from about 0.001% to about 20% by weight of the first surfactant are surfactants of formula II.

4. The detergent composition according to claim 1 , wherein at least about 25% by weight of the first surfactant are surfactants having m+n=10, m+n=11, m+n=12, and m+n=13, wherein n is 0, 1, or 2, or m is 0, 1, or 2.

5. The detergent composition according to claim 1 , wherein X is selected from the group consisting of sulfates, sulfonates, amine oxides, polyoxyalkylene, polyhydroxy moieties, phosphate esters, glycerol sulfonates, polygluconates, polyphosphate esters, phosphonates, sulfosuccinates, sulfosuccaminates, polyalkoxylated carboxylates, glucamides, taurinates, sarcosinates, glycinates, isethionates, dialkanolamides, monoalkanolamides, monoalkanolamide sulfates, diglycolamides, diglycolamide sulfates, glycerol esters, glycerol ester sulfates, glycerol ethers, glycerol ether sulfates, polyglycerol ethers, polyglycerol ether sulfates, sorbitan esters, polyalkoxylated sorbitan esters, ammonioalkanesulfonates, amidopropyl betaines, alkylated quats, alkyated/polyhydroxyalkylated quats, alkylated/polyhydroxylated oxypropyl quats, imidazolines, 2-yl-succinates, sulfonated alkyl esters, sulfonated fatty acids, and mixtures thereof.

6. The detergent composition according to claim 1 further comprising an adjunct cleaning additive selected from the group consisting of 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 filler or carrier, an alkalinity system, a pH control system, and a buffer, and mixtures thereof.

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

8. The detergent composition according to claim 1 , wherein said detergent composition comprises an enzyme selected from the group consisting of lipase, amylase, protease, mannanase, cellulase, pectinase, and mixtures thereof.

9. The detergent composition according to claim 1 further comprising a second surfactant selected from the group consisting of an anionic surfactant, a cationic surfactant, a nonionic surfactant, an amphoteric surfactant, a zwitterionic surfactant, or mixtures thereof; or wherein said detergent composition comprises an anionic surfactant selected from alkyl benzene sulfonates, alkoxylated alkyl sulfates, alkyl sulfates, and mixtures thereof.

10. The detergent composition according to claim 1 , wherein said detergent composition is a form selected from the group consisting of a granular detergent, a bar-form detergent, 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 detergent contained on or in a porous substrate or nonwoven sheet, a automatic dish-washing detergent, a hard surface cleaner, a fabric softener composition, and mixtures thereof.

11. The detergent composition according to claim 1 , wherein from about 0.1% to about 100% of the carbon content of the first surfactant is derived from renewable sources.

12. A method of pretreating or treating a soiled fabric comprising contacting the soiled fabric with the detergent composition according to claim 1 .
