Description

A gelling polysaccharide extracted from giant brown seaweed, useful in viscosity studiesAlginic acid sodium salt is widely utilized in food industry as flavorless gum, which enhances viscosity and as an emulsifier. It finds application as thickener for reactive dyestuffs, which is used in textile screen printing and carpet jet-printing. It is used indigestion tablets and the preparation of dental impressions. As a polymer, it combines with chitosan to synthesize a biodegradable porous scaffold, which is useful for tissue engineering applications. It acts as a food additive and involved in the production of gel-like foods such as bakers. It is employed as thickener for reactive dyestuffs in textile screen-printing and carpet jet-printing. It is also used as encapsulating agents of microparticles of beta-galactosidae and in the preparation of alginate hydrogels with tunable mechanical properties.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
