Polysucrose 400, 1 x 20 kg

Polysucrose 400 is a synthetic high molecular weight polymer made by the copolymerization of sucrose and epichlorohydrin. The molecules have a branched structure with a high content of hydroxyl groups giving a good solubility in aqueous solutions.

The reactivity and stability of Polysucrose 400 are determined by its hydroxyl groups and the glycosidic bonds in the sucrose residues. Polysucrose is stable in alkaline and neutral solutions. At pH values lower than 3, it is rapidly hydrolysed, especially at elevated temperatures. In neutral solutions, Polysucrose 400 can be sterilized by autoclaving at 100°C for 30 minutes without any degradation.

Polysucrose 400 is readily soluble in aqueous solutions when added slowly to the liquid with constant stirring. Concentrations up to 50% (w/v) can easily be obtained.
