USE OF A CRYSTALLISATION-INHIBITING ADDITIVE FOR SURFACE-ACTIVE NONIONIC GLYCOSIDES

摘要

Addition of an anionic derivative of a glycoside of formula (I): R(A)s(G)n wherein R is an aliphatic hydrocarbon group having 6-20, preferably 8-16 carbon atoms, G is a saccharide residue, A is an oxyalkylene having 2-4 carbon atoms or 3-oxy-2-hydroxy-propylene, n is a number from 1 to 10, preferably a number from 1 to 4, and s is a number from 0 to 5; or a nonionic alkylene oxide adduct of a glycoside of formula (I), wherein the alkylene oxide contains 2-4 carbon atoms, inhibits or prevents crystallisation of an aqueous concentrate of a glycoside of formula (I). The addition of the derivative or the adduct also yields relatively small changes of the properties of the glycoside mixture.
