Opening claim text (preview).
1 . Mixture of compounds (A), said mixture comprising a mixture of compounds according to the general formula (I) wherein R 1 is C 1 -C 4 -alkyl, linear or branched, or hydrogen, R 2 is —CH 2 CH 2 R 1 , each G 1 is glucose or xylose, wherein in the range of from 70 to 95% mole-% are glucose and from 5 to 30 mole-% are xylose, and the average of x is in the range of from 1.1 to 4. 2 . Mixture according to claim 1 wherein R 1 is ethyl or n-propyl. 3 . Mixture according to claim 1 wherein the average of x is in the range of from 1.15 to 1.9. 4 . Mixture according to claim 1 wherein in specific molecules with x being 2 or more, the G 1 groups are selected from glucose being linked in 1,4-position(s). 5 . Mixture according to claim 1 which further comprises at least one isomer of a compound according to general formula (I), said isomer bearing an alkyl group being isomeric to CH 2 CHR 1 CH 2 CHR 1 . 6 . Process of making a mixture according to claim 1 , said process comprising the step of reacting a mixture of glucose and xylose or the respective di- or polysaccharides with an alcohol according to formula (II) R 1 CH 2 —CH 2 —CHR 1 —CH 2 —OH (II) R 1 being defined as above, in the presence of a catalyst. 7 . Aqueous formulation comprising in the range of from 0.05 to 50% by weight of one mixture of compounds according to claim 1 . 8 . Aqueous formulation according to claim 7 , which further comprises at least one by-product or starting material, stemming from the synthesis of the mixture of compounds. 9 . (canceled) 10 . Process for cleaning hard surfaces or fibers, the process comprising 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 . 11 . Process according to claim 10 , further comprising a degreasing the hard surface or the fiber.
