Abstract

Official abstract text for this publication.

The present invention refers to the use of a composition comprising two or more compounds of the general formula (I) as anti-greying agent in a laundry process.

First claim

Opening claim text (preview).

The invention claimed is: 1. An anti-greying agent in a laundry process which comprises a composition comprising two or more compounds of the general formula (I), wherein R is unsubstituted branched C 13 alkyl and has an average number of branching in the range from 0.9 to 2.9; G 1 is selected from monosaccharides with 5 or 6 carbon atoms; x is in the range of from 1 to 1.8 and refers to average values, and wherein the two or more compounds differ in the average number of branching of R and/or G 1 and/or x. 2. The agent according to claim 1 , wherein G 1 is selected from the group consisting of glucose, xylose, arabinose, rhamnose and mixtures thereof, and/or x is in the range of from 1.05 to 1.8. 3. The agent according to claim 1 , wherein G 1 is selected from the group consisting of glucose, xylose, arabinose, rhamnose and mixtures thereof, and/or x is in the range of from 1.10 to 1.8. 4. The agent according to claim 1 , wherein G 1 is glucose and/or xylose and x is in the range of from 1.05 to 1.8. 5. The agent according to claim 1 , wherein G 1 is glucose and x is in the range of from 1.10 to 1.8. 6. The agent according to claim 1 , wherein R has an average number of branching in the range from 1.8 to 2.9. 7. The agent according to claim 1 , wherein R has an average number of branching in the range from 2.0 to 2.5. 8. The agent according to claim 1 , wherein the two or more compounds of the general formula (I) differ in the average number of branching of R. 9. The agent according to claim 1 , wherein the laundry process is carried out at a temperature ranging from 5 to 120° C. 10. The agent according to claim 1 , wherein the anti-greying agent is formulated in a dry or liquid formulation. 11. The agent according to claim 10 , wherein the formulation further comprises additives selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants, enzymes, bleaching agents, peroxygen compounds, optical brightener, complexing agents, polymers, soaps, silicon based defoamers, bleaching agents, colorants, dye transfer inhibitors and mixtures thereof. 12. The agent according to claim 10 , wherein the formulation further comprises additives selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants, enzymes, bleaching agents, peroxygen compounds, optical brightener, complexing agents, polycarboxylates, soaps, silicon based defoamers, bleaching agents, colorants, dye transfer inhibitors and mixtures thereof. 13. The agent according to claim 10 , wherein the formulation is a single dose formulation or a high concentrated powder formulation having a bulk density of above 600 g/l. 14. The agent according to claim 1 , wherein the anti-greying agent reduces greying of a washed fabric. 15. The agent according to claim 6 , wherein G 1 is selected from the group consisting of glucose, xylose, arabinose, rhamnose and mixtures thereof and x is in the range of from 1.10 to 1.8. 16. The agent according to claim 15 , wherein R has an average number of branching in the range from 2.0 to 2.5. 17. The agent according to claim 16 , wherein the two or more compounds of the general formula (I) differ in the average number of branching of R. 18. The agent according to claim 17 , wherein the laundry process is carried out at a temperature ranging from 5 to 120° C. 19. The agent according to claim 18 , wherein the anti-greying agent is formulated in a dry or liquid formulation.
