Property:

Sodium alginate is white or light yellow powder, almost odorless and tasteless. Sodium alginate soluble in water, insoluble in ethanol, ether, chloroform and other organic solvents.

Usage:

1. Sodium alginate is used to replace starch and gelatin as a stabilizer for ice cream, which can control the formation of ice crystals, improve the taste of ice cream, and stabilize mixed drinks such as sugar water sorbet, iced sherbet, and frozen milk.

2. Sodium alginate is used in some liquid drugs to enhance viscosity and improve the suspension of solids. Propylene glycol alginate can improve the stability of the emulsion.

3. Sodium alginate is used as active dye paste in printing and dyeing industry, which is better than grain starch and other pastes. The printed textile pattern is bright, the lines are clear, the color amount is high, the color is uniform, and the permeability and plasticity are good.

4. In medicine, the PS type gastrointestinal double-contrast barium sulfate preparation made of alginate sulfate dispersant has the characteristics of low viscosity, fine particle size, good wall attachment and stable performance. Using seaweed gum instead of rubber and gypsum as dental impression material is not only cheap, easy to operate, but also more accurate to print teeth.
