Overview

Description

The most widely used polysaccharide in wound healing is alginate. Alginates are a general term for a family of polysaccharides produced by seaweeds, brown algae and bacteria. Alginates are heteropolysaccharides made from two randomly arranged uronic acid and sugar molecules, namely a G block and an M block. In general, alginates with more G blocks have stiffer chains than alginates with more M blocks, suggesting a more flexible structure with higher swelling capacity. These two uronic acids can bind to metal ions such as sodium and calcium that are widely used in alginate dressing formulations. Calcium alginate is an insoluble form of alginate with high swelling capacity. It can be woven into flexible patches or ribbons for filling cavities or tunnel wounds. Calcium alginate absorbs 15-20 times its original weight and its non-stick surface allows it to be easily removed from the wound site.

Features

·High swelling capacity
·High dispersion
·Good gel properties
·Strong water retention

Application

·Binders, thickeners and water-retaining agents used in food, under the influence of salt in food, calcium-sodium exchange forms thickening high-calcium glue, mostly used with sodium alginate
·Can be used directly as a hemostatic agent in pharmaceuticals
·For industrial welding materials: binders, plasticizers
