Product description

Introduction of sodium alginate:

Sodium alginate, a kind of natural polysaccharide, with pharmaceutical preparations accessories required stability, solubility, viscosity, and security. In 1881, the British chemist E.C.S tanford first alginate of brown algae extract for scientific research. He found that the alginic acid extract has several interesting features, it has a concentrated solution, forming gel and film forming ability. Based on this, he put forward several industrialized production application. Alginate until 50 years later, however, on a large scale industrial production. Commercial production began in 1927, is now the world produce about 30000 tons per year, 30% of them used in the food industry, the rest used for other industry, the pharmaceutical industry and dental.

Properties of sodium alginate:

1. Good hydrophily
2. Good fluidity
3. Thickening
4. Health protection property
5. Gel forming capability
