Abstract

An alkyl glyceryl sulfonate and/or sulfate surfactant mixture of oligomers and a detergent composition using the same to provide improved starch soil cleaning.

Claims

wherein the weight percentage of monomers is from 0 wt % to 60 wt % by weight of the alkyl glyceryl sulfonate and/or sulfate surfactant mixture.

3. The detergent composition according to claim 1 wherein the alkyl glyceryl sulfonate surfactant, the alkyl glyceryl sulfate surfactant, and mixtures thereof is selected from dimers, trimers, tetramers, pentamers, hexamers, heptamers, and mixtures thereof.

4. The detergent composition according to claim 1 wherein the alkyl glyceryl sulfonate surfactant, alkyl glyceryl sulfate surfactant, and mixtures thereof comprise an alkyl chain length from C_10-44.

5. The detergent composition according to claim 1 wherein the alkyl glyceryl sulfonate surfactant, alkyl glyceryl sulfate surfactant, and mixtures thereof comprises a C_12-18 alkyl chain;

wherein the alkyl chain may be a linear or comprise a C_1-4 alkyl branch.

6. The detergent composition according to claim 1 wherein the detergent composition further comprises from 30% to 80% by weight of the liquid detergent composition of a aqueous liquid carrier and from about 5% to about 10% by weight of the composition of a linear amine oxide.

7. The detergent composition according to claim 1 wherein the detergent composition further comprises from about 0.1% to about 20% by weight of the detergent composition of an anionic surfactant, a nonionic surfactant, and mixtures thereof.

8. The detergent composition according to claim 1 wherein the detergent composition further comprises from 30% to 80% by weight of the liquid detergent composition of a aqueous liquid carrier and from about 3% to about 8% by weight of the composition of a linear amine oxide and from about 0.1% to about 20% by weight of the detergent composition of a nonionic surfactant.

9. The detergent composition according to claim 7 or 8 wherein the nonionic surfactant selected from the group of C₈-C₂₂ aliphatic alcohols with 1 to 25 moles of ethylene oxide, alkylpolyglycosides, fatty acid amide surfactants, and mixtures thereof.

10. The detergent composition of claim 9 further comprises from 0.01% to 20% by weight of the detergent composition of a solvent and from 0% to about 15% by weight of the detergent composition of a hydrotrope.

11. The detergent composition of claim 10 further comprising from 0% to about 15% by weight of the detergent composition of a hydrophobic block polymer.

12. The detergent composition according to claim 10 further comprising from about 0.1% to about 4% by weight of the detergent composition of magnesium ions, from about 0% to about 15% by weight of the detergent composition of a diamine, or mixtures thereof.

13. The detergent composition according to claim 10 further comprising from about 0.01% to about 15% by weight of the detergent composition of a suds boosting polymer, a polymeric suds stabilizer, or mixtures thereof.
