Carmellose Calcium BP
Carboxymethyl cellulose (CMC) or cellulose gum or tylose powder is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its Calcium salt, calcium carboxymethyl cellulose.
Calcium CMC is calcium salt of Carboxy Methyl Cellulose. It is highly pure white powder used for tablet disintegration. It can be used as where it is used as a binder, diluent, and disintegrant.
