Abstract

De nouveaux dérivés alcoxylés de thiodiglycolsulfoxyde ou de thiodiglycolsulfone correspondent à la formule générale (I), dans laquelle X1 et/ou X2 représentent des restes alkyle et/ou acyle, substitués par hydroxyle, d'acides monocarboxyliques d'alkyle, ayant chacun 8 à 30 atomes de C; R désigne hydrogène ou méthyle; z est égal à 1(sulfoxydes) ou 2 (sulfones), n est compris entre 0 et 25 et m entre 1 et 25. Un procédé de production de ces composés commence par l'alcoxylation du thiodiglycol, la réaction des thiodiglycols alcoxylés avec des époxydes d'alpha-oléfines ou des acides monocarboxyliques, suivie de l'oxydation avec du péroxyde d'hydrogène de manière à obtenir le sulfoxyde ou sulfone correspondants. Les composés alcoxylés de thiodiglycol de la formule générale (I) sont utilisés comme agents d'avivage dans des produits de lavage et/ou de rinçage de matières textiles, notamment dans le bain avivant de rinçage, de manière optimale sous forme d'un mélange aqueux de substances actives.
