Carboxymethyl starch

Carboxymethyl starch is a white pale yellow powder: odorless, insoluble in dry ethanol, ether, acetone, and other organic solvents. It can swell after being placed in cold water for 15 minutes. It is unstable in neutral alkaline environments and produces white turbidity and precipitation in the presence of strong acids and metal salts
  • Detailed Description

Carboxymethyl starch is a white pale yellow powder: odorless, insoluble in organic solvents such as ethanol, ether, acetone, etc. It can swell after 15 minutes in cold water. It is unstable in neutral alkaline environments and produces white turbidity and precipitation in the presence of strong acids and metal salts. It can form a clear and transparent solution in cold water. Methyl starch has water absorption, is soluble in water, fully expands, and its volume can reach 200-300 times the original. Its water absorption is better than that of methyl cellulose fiber because it contains acid groups. Due to its integrated ion exchange and heavy metal ion calcium interaction, starch also has certain film-forming properties, water retention, thickening, permeability, and stability.

Main uses

 

Due to the above characteristics, carboxymethyl starch CMS has been widely used and praised in industries such as food, synthetic detergents, textiles, printing and dyeing, oil fields, pharmaceuticals, papermaking, fertilizer granulation, etc. For specific usage, please refer to the instructions for using carboxymethyl starch CMS.

 

Packaging and storage

 

The packaging is 25 kilograms per bag. The above products are prone to moisture absorption, using plastic bags and moisture-proof cowhide bags for external use. They should be stored in a ventilated, cool, dry place, and protected from moisture and rain. Prevent exposure to sunlight during transportation.
