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

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

(B) in the range of from 85 to 15% by weight of at least one compound of the general 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 1 -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 C 3 -C 9 -alkyl, linear or branched,
wherein the percentages 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 x and y are numbers in the range of from 1.15 to 1.9.

4 . 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.

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

6 . 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 .

7 . 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 .

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

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

10 . (canceled)

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

12 . The process of claim 11 , further comprising a degreasing.

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

14 . The aqueous formulation of claim 13 , further comprising a by-product, stemming from the synthesis of compound (A) or compound (B).
