Abstract: The invention concerns a mixture comprising alkylation products of monosaccharides, of the following formula (I): (CnH2n-1On)-R , which are acetalized in position 1 by the radical R , in which formula n stands for the number 5 or 6 and R designates a C1 to C4 alkyl group, a C1 to C3 mono or dihydroxyalkyl group or a C1 to C3 methoxy or ethoxyalkyl group, and epoxides of formula (II) wherein R and R independently of each other mean hydrogen or an alkyl or alkenyl radical which can additionally carry C1 to C4 carboxylic acid alkylester groups and can be interrupted by non-adjacent oxygen atoms, in which the total number of carbon atoms of the two radicals R and R has to be between 4 and 60, said mixture containing 50 to 100 wt % monoalkylation products and 0 to 50 wt % higher alkylation products, at least one of the possible regio-isomer monoalkylation products being present in an amount of at least 30 wt % if n equals 6 or at least 40 wt % if n equals 5, in each case relative to the total of all the monoalkylation products formed.
