1、CAS No.:25736-27-0

2、Chemical formula:(C5H7NO3)n

3、Molar mass:variable

4、Chemical structure:

5、properties:

Water retentivity:it allows absorbing and binding water approx. 5000 times greater than its own weight. The higher the molecular weight, the higher the water retentivity.

Hydrophilicity:the lower the molecular weight, the higher soluble in water.

Viscosity: it can be used to adjust property and condition of a product. The higher the molecular weight, the higher the viscosity.

Biodegradability: it can be degraded by microorganisms into water and carbon dioxide. Polyglutamic acid is eco-friendly.
