Abstract (en)

[origin: DE4232165A1] The method proposed provides surface-active substances with improved cleaning power by hydrolysing, at temperatures of 70 to 180 DEG C and pressures of 1 to 50 bar for 5 min to 10 days, aqueous pastes of alkyl and/or alkenyl oligoglycosides of the formula R<1>O-[G]p in which R<1> is an alkyl and/or alkenyl group with 4 to 22 carbon atoms, G is a saccharide group with 5 or 6 carbon atoms and p is a number from 1 to 10.
