Abstract

The current invention is directed towards compounds of the general formula (I), wherein the integers are defined as follows: R 1 is —(CH 2 )nCH(CH 3 ) 2 , R 2 is —(CH 2 ) n+2 CH(CH 3 ) 2 , G 1 selected from monosaccharides with 4 to 6 carbon atoms, x in the range of from 1.1 to 4, n is a number in the range of from zero to 3.

First claim

The invention claimed is:

1. Mixture of compounds of general formula (I)

wherein:
R 1 is —(CH 2 ) n CH(CH 3 ) 2 ,
R 2 is —(CH 2 ) n+2 CH(CH 3 ) 2 ,
G 1 selected from monosaccharides with 4 to 6 carbon atoms,
x in the range of from 1.1 to 4,
n is a number in the range of from zero to 3.

2. Mixture of compounds according to claim 1 , characterized in that G 1 is selected from glucose, arabinose and xylose.

3. Mixture of compounds according to claim 1 , characterized in that x is in the range of from 1.15 to 1.9.

4. Mixture of compounds according to claim 1 , characterized in that n is zero.

5. Mixture of compounds according to claim 1 , characterized in that in molecules with x being 2 or more, the saccharide groups are linked in 1,4-position(s).

6. Mixture, containing at least one mixture of compounds according to claim 1 and at least one of its isomers in which the sugar part is identical to G 1 but the alkyl group is different.

7. Mixture, containing at least one mixture of compounds according to claim 1 and at least one non-ionic surfactant, selected from alkoxylated fatty alcohols and hydroxyl-group containing non-ionic surfactants.

8. Process for making a mixture of compounds according to claim 1 , comprising the step of reacting an alcohol of the general formula (II)

with a monosaccharide, disaccharide or polysaccharide bearing a G 1 group in the presence of a catalyst.

9. Aqueous formulation containing in the range of from 0.05 to 50% by weight of one mixture of compounds according to claim 1 .

10. An aqueous formulation comprising from 0.05 to 50% by weight of said mixture of compounds of general formula (I) according to claim 1 , and further comprising at least one by-product or starting material, stemming from the synthesis of said mixture of compounds.

11. Process for cleaning hard surfaces or fibers by contacting a hard surface or fiber or an arrangement of fibers with at least one aqueous formulation containing a mixture of compounds according to claim 1 .

12. Process according to claim 11 , characterized in that the cleaning comprises a degreasing.
