Abstract

The current invention is directed towards mixtures, comprising (A) in the range of from 15 to 85% by weight of at least one compound of the general formula (I) (B) in the range of from 85 to 15% by weight of at least one compound of the general formula (II), wherein the integers are defined as follows: R 1 is C 3 -C 4 -alkyl, linear or branched, R 2 is C 5 -C 6 -alkyl, linear or branched, G 1 , G 2 are different or identical and selected from monosaccharides with 4 to 6 carbon atoms, x, y are numbers in the range of from 1.1 to 4, R 3 is C 3 -C 9 -alkyl, linear or branched, the percentages referring to the total mixture.

First claim

The invention claimed is:

1. A mixture, comprising:
(A) from 15 to 85% by weight of at least one compound of formula (I):

and
(B) from 85 to 15% by weight of at least one compound of formula (II);
R 3 —CH 2 —O-(G 2 ) y -H  (II),

wherein:
R 1 is C 3 -C 4 -alkyl, linear or branched,
R 2 is C 5 -C 6 -alkyl, linear or branched,
G 1 , G 2 are each independently monosaccharides with 4 to 6 carbon atoms,
x, y are 1.4,
R 3 is C 3 -C 9 -alkyl, linear or branched,
wherein the percentages of compound (A) and compound (B) refer to the total mixture, and compound (A) is different from compound (B).

2. The mixture of claim 1 , wherein G 1 and G 2 are selected from the group consisting of glucose, arabinose, and xylose.

3. The mixture of claim 1 , wherein R 3 is selected from the group consisting of CH(C 2 H 5 )—(CH 2 ) 3 —CH 3 , n-heptyl, and n-nonyl.

4. The mixture according to claim 1 , comprising at least two of the compounds (A).

5. The mixture of claim 1 , wherein in one compound (A), R 1 is isopropyl and R 2 is CH 2 —CH 2 —CH(CH 3 ) 2 .

6. The mixture of claim 1 , wherein in one compound (A), R 1 is n-C 3 H 7 and R 2 is n-C 5 H 11 .

7. A process for making the mixture of claim 1 , comprising mixing at least one compound (A) with at least one compound (B).

8. A process for cleaning a hard surface or fiber, comprising contacting the mixture of claim 1 with the hard surface or fiber.

9. The process of claim 8 , further comprising a degreasing.

10. An aqueous formulation, comprising:
from 35 to 80% by weight of the mixture of claim 1 ; and
water.

11. The aqueous formulation of claim 10 , further comprising a by-product, stemming from the synthesis of compound (A) or compound (B).

12. The mixture of claim 1 , which is a clear mixture.

13. The aqueous formulation of claim 10 , which is a clear aqueous formulation.

14. The mixture of claim 1 , which is a clear mixture as determined by a Hazen number for a clear liquid and measured according to DIN EN ISO 6271-1 or 6271-2.

15. A mixture, comprising:
(A) from 15 to 85% by weight of at least one compound of formula (I):

and
(B) from 85 to 15% by weight of at least one compound of formula (II):
R 3 —CH 2 —O-(G 2 ) y -H  (II),

wherein:
R 1 is C 3 -C 4 -alkyl, linear or branched,
R 2 is C 5 -C 6 -alkyl, linear or branched,
G 1 , G 2 are each independently monosaccharides with 4 to 6 carbon atoms,
x, y are numbers in the range of from 1.1 to 4,
R 3 is a branched C 3 -C 6 -alkyl or a linear C 3 -C 4 alkyl,
wherein the percentages of compound (A) and compound (B) refer to the total mixture, and compound (A) is different from compound (B).

16. The mixture of claim 15 , wherein R 3 is a branched C 3 -C 6 -alkyl.

17. An aqueous formulation, comprising:
from 35 to 80% by weight of the mixture of claim 15 ; and
water.

18. The mixture of claim 15 , wherein in molecules with x or y, respectively, being 2 or more, the sugar molecules are linked in 1,4-position(s).
