Abstract

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

First claim

The invention claimed is:

1. A composition comprising nonionic surfactants, wherein the nonionic surfactants consist of:
(A) two or more compounds of the general formula (I),

wherein R is a mixture of unsubstituted linear C 12 -alkyl and C 14 -alkyl, G 1 is arabinose and/or rhamnose, or G 1 is a mixture of glucose, arabinose and xylose; x is in the range of from 1 to 10 and refers to average values, and wherein the two or more compounds differ in G 1 and/or x; and
(B) optionally one or more nonionic surfactants selected from the group consisting of C 8 -C 22 alkyl ethoxylates, C 6 -C 12 alkyl phenol alkoxylates, block alkylene oxide condensate of C 6 to C 12 alkyl phenols, alkylene oxide condensates of C 8 -C 22 alkanols and ethylene oxide/propylene oxide block polymers, condensation products of C 12 -C 15 alcohols with from 5 to 20 moles of ethylene oxide per mole of alcohol, polyhydroxy fatty acid amides, and mixtures thereof.

2. The composition according to claim 1 , wherein x is in the range of from 1.05 to 2.5.

3. The composition according to claim 1 , wherein G 1 is arabinose and/or rhamnose and x is in the range of from 1.05 to 2.5.

4. The composition according to claim 1 , wherein G 1 is arabinose and/or rhamnose and x is in the range of from 1.10 to 1.8.

5. A dry or liquid formulation comprising the composition of claim 1 .

6. The dry or liquid formulation according to claim 5 , wherein the formulation further comprises additives selected from the group consisting of anionic 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.

7. The dry or liquid formulation according to claim 5 , wherein the formulation is a single dose formulation or a high concentrated powder formulation having a bulk density of above 600 g/l.

8. A nonionic surfactant consisting of:
(A) two or more compounds of the general

formula (I), wherein R is a mixture of unsubstituted linear C 12 -alkyl and C 14 -alkyl, G 1 is arabinose and/or rhamnose, or G 1 is a mixture of glucose, arabinose and xylose; x is in the range of from 1 to 10 and refers to average values, and wherein the two or more compounds differ in G 1 and/or x; and
(B) optionally one or more nonionic surfactants selected from the group consisting of C 8 -C 22 alkyl ethoxylates, C 6 -C 12 alkyl phenol alkoxylates, block alkylene oxide condensate of C 6 to C 12 alkyl phenols, alkylene oxide condensates of C 8 -C 22 alkanols and ethylene oxide/propylene oxide block polymers, condensation products of C 12 -C 15 alcohols with from 5 to 20 moles of ethylene oxide per mole of alcohol, polyhydroxy fatty acid amides, and mixtures thereof.

9. The surfactant according to claim 8 , wherein the surfactant is a surfactant for a laundry process.

10. An anti-greying agent in a laundry process comprising nonionic surfactants, wherein the nonionic surfactants consist of:
(A) two or more compounds of the general formula (I),

wherein R is a mixture of unsubstituted linear C 12 -alkyl and C 14 -alkyl, G 1 is arabinose and/or rhamnose, or G 1 is a mixture of glucose, arabinose and xylose; x is in the range of from 1 to 10 and refers to average values, and wherein the two or more compounds differ in G 1 and/or x; and
(B) optionally one or more nonionic surfactants selected from the group consisting of C 8 -C 22 alkyl ethoxylates, C 6 -C 12 alkyl phenol alkoxylates, block alkylene oxide condensate of C 6 to C 12 alkyl phenols, alkylene oxide condensates of C 8 -C 22 alkanols and ethylene oxide/propylene oxide block polymers, condensation products of C 12 -C 15 alcohols with from 5 to 20 moles of ethylene oxide per mole of alcohol, polyhydroxy fatty acid amides, and mixtures thereof.

11. The composition according to claim 1 , wherein x is in the range of from 1.10 to 1.8.
