Description
Sodium Carboxymethyl Cellulose (CMC) is a high-quality, food-grade polysaccharide derived from cellulose. It is chemically modified through carboxymethylation, which enhances its water solubility and viscosity properties. This white to cream-colored powder is stable, non-toxic, and biodegradable, making it suitable for a wide range of applications, particularly in the food industry.
Specification:
Physical Form: White or cream-colored powder
