Abstract (en)

[origin: DE4225224A1] Storable non-ionic tensides with improved crystallisation resistance are obtained if, to aqueous preparations containing alkyl and/or alkenyl oligoglycosides of formula (I): R<1>O-[G]p in which R<1> is a linear alkyl and/or alkenyl radical with 6 to 22 carbon atoms, G is a sucrose radical with 5 or 6 carbon atoms and p represents numbers from 1 to 10, are added crystallisation moderators selected from the group consisting of a) alkyl oligoglycosides based on short-chained primary alcohols, b) alkyl oligoglycosides based on Guerbet alcohols, c) alkyl oligoglycosides based on polyoles, d) short-chained primary alcohols, e) fatty alcohol polyglycol ethers, f) polyethylene glycols, g) glucose and h) iron-(III)-ions.
