Uses and synthesis of Sodium carboxyl methylstarch powder

Sodium carboxyl methylstarch powder is white or yellow powder, odourless, tasteless, non-toxic, easy to absorb moisture in heat.Sodium carboxyl methylstarch CAS 9063-38-1 dissolves in water to form a colloidal solution, light and heat stable.Sodium carboxyl methylstarch Raw Materials does not dissolve in ethanol, ether, chloroform and other organic solvents. Sodium carboxyl methylstarch Raw Materials Insoluble in ethanol, ether, chloroform and other organic solvents.

Applications / Functions of Sodium carboxyl methylstarch powder

1. Thickener; emulsion stabilizer; Sodium carboxyl methylstarch powder can be used in ice cream (0.2%～0.5%); preventing the aging of bread (0.05%～0.2%).
2. It is a water-soluble anionic polymer compound, used as suspension and stabilisation in water-based paints, as an additive in warp sizing agents, and as a dyeing auxiliary.

Physicochemical Property of Sodium carboxyl methylstarch powder

Sodium carboxyl methylstarch CAS 9063-38-1 The aqueous solution will be partially decomposed by atmospheric bacteria, which will reduce the viscosity. Harder to hydrolyse than normal starch. Insoluble in methanol, ethanol and other organic solvents. pH 6.7-7.0 for 1% aqueous solution. aqueous solution is more stable in alkali, but worse in acid.

Production methodprocess of Sodium carboxyl methylstarch powder

• Sodium carboxyl methylstarch Raw Materials is obtained by treating starch with sodium hydroxide and reacting it with monochloroacetic acid or acrylonitrile.
• The residual sodium monochloroacetate and sodium hydroxide are washed away with sulphuric acid, and Sodium carboxyl methylstarch powder is obtained after dehydration and drying.
