Ultrapure Sodium Alginate

Resource

Sodium Alginate is a highly biocompatible material which could be used in medical devices, pharmaceutical excipients, and pharmaceutical intermediates. Matexcel offers ultrapure sodium alginate with good quality control and assurance.

What is Sodium Alginate

Sodium alginate is a linear polysaccharide derivative of alginic acid comprised of 1,4-β-d-mannuronic (M) and α-l-guluronic (G) acids. The content of 1,4-β-d-mannuronic (M) and α-l-guluronic (G) acids (or usually mentioned G/M ratio) is determined by the source of algae. Different G/M ratio sodium alginate product has different gel characteristics.
