Abstract

The invention relates to a mixture composition comprising glucolipids, to its use for producing formulations and to formulations comprising this mixture composition.

First claim

The invention claimed is:

1. A mixture composition, comprising:
a glucolipid of formula (I) or a salt thereof

wherein
R 1 and R 2 =independently of one another, are an identical or different organic radical having from 2 to 24 carbon atoms,
wherein the mixture composition comprises at least 60-90% by weight of a glucolipid GL-C10C10 of formula (I) with R 1 and R 2 ═(CH 2 ) 6 —CH 3 , wherein the percentages by weight refer to a sum of all of the glucolipids of formula (I) present, and
wherein the mixture composition comprises from 5% by weight to 25% by weight of GL-C8C10, from 3% by weight to 17% by weight of GL-C10C12:1, from 2% by weight to 15% by weight of GL-C10C12, wherein the percentages by weight refer to the sum of all of the glucolipids of formula (I) present.

2. The mixture composition according to claim 1 , wherein the mixture composition comprises
from 0% by weight to 5% by weight of GL-C10,
wherein the percentages by weight refer to the sum of all of the glucolipids of formula (I) present.

3. The mixture composition according to claim 1 , wherein the mixture composition comprises at least 60% by weight of glucolipids of formula (I), wherein the percentages by weight refer to a total dry mass of the overall mixture composition.

4. A formulation comprising the mixture composition according to claim 1 .

5. The formulation according to claim 4 , comprising at least one further surfactant.

6. The formulation according to claim 5 , wherein the total surfactant content of the formulation is from 5 to 60% by weight based on the total formulation.

7. A surface cleaner comprising the mixture composition according to claim 1 .

8. The mixture composition according to claim 1 , wherein the mixture composition comprises at least 80% by weight of glucolipids of formula (I), wherein the percentages by weight refer to a total dry mass of the overall mixture composition.

9. The mixture composition according to claim 1 , wherein the mixture composition comprises at least 90% by weight of glucolipids of formula (I), wherein the percentages by weight refer to a total dry mass of the overall mixture composition.

10. The formulation according to claim 5 , comprising a surfactant selected from the group consisting of anionic, nonionic, cationic, and amphoteric surfactants.

11. A surface cleaner comprising the formulation mixture according to claim 5 .

12. The formulation according to claim 10 , wherein the total surfactant content of the formulation is from 5 to 60% by weight based on the total formulation.
