Abstract
(DE)
Die Erfindung betrifft Malatyl-Polysaccharide, erhältlich durch Umsetzung von Polysacchariden und cis-Epoxysuccinat oder Epoxycarbonsäuren, Verfahren zu deren Herstellung sowie deren Anwendung in Waschmitteln, als Verdickungsmittel, als Komplexierungsmittel für mehrwertige Kationen und als Ionentauscher für wäßrige Systeme oder als Hilfsstoff in pharmazeutischen Anwendungen (z.B. Tablettensprengmittel, Suspensionsstabilisator etc.) oder als Inhaltsstoff für Hygieneartikel.
(EN)
The invention relates to malatyl polysaccharides which are obtained by reacting polysaccharides and cis epoxy succinate or epoxy carboxylic acids. The invention further relates methods for producing them and to their use in washing agents, as thickeners, as complexing agents for polyvalent cations and as ion exchangers for aqueous systems or as adjuvants in pharmaceutical applications (for example disintegrants, suspension stabilizers etc.) or as ingredients for hygienic articles.
(FR)
L'invention concerne des polysaccharides de malatyle, obtenus par réaction de polysaccharides et de cis-époxysuccinate ou d'acides époxycarboxyliques, leur procédé de production, ainsi que leur utilisation dans des détergents, comme épaississant, comme agent complexant pour des cations polyvalents et comme échangeur d'ions pour des systèmes aqueux, comme agent dans des applications pharmaceutiques (par exemple, désintégrant de comprimés, stabilisateur de suspensions, etc.) ou comme constituant pour des articles d'hygiène.
