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 according to claim 1 and at least one further isomer being different from each of compound according to general formulae (I), compound (II) and (III).

7. Process for making a mixture of compounds according to claim 1 , comprising the step of reacting a mixture of alcohols of the general formulae (IV), (V) and (VI)

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

8. Process for cleaning hard surfaces comprising contacting said hard surface with a mixture of compounds according to claim 1 .

9. Process according to claim 8 , characterized in that the cleaning comprises a degreasing.

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

11. Aqueous formulation according to claim 10 , characterized that it further contains at least one by-product or starting material, stemming from the syntheses of compounds according to general formulae (I), (II) and (III).

12. Mixture of alcohols, comprising
