Cross-linked sodium carboxymethyl cellulose is also known as croscarmellose sodium or modified cellulose gum. Crosslinked sodium carboxymethylcellulose (CMC), croscarmellose, is prepared by the reaction of Na-CMC with acids. The raw material is usually a high viscosity sodium CMC with a low degree of substitution. The cross-linking reduces water solubility while still allowing the material to swell (like a sponge) and absorb many times its weight in water. As a result, it provides superior drug dissolution and disintegration characteristics. Cross-linked sodium carboxymethyl cellulose is used in tablets of table-top sweeteners and dietary food supplements, as it facilitates disintegration in aqueous solutions, with a maximum level of use of 30 g/kg.
The global carboxymethyl cellulose (CMC) market was estimated at $1,151.7 Million in 2014 and is projected to register a CAGR of 4.2% between 2015 and 2020. Carboxymethyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl group in its chain. CMC is physiologically inert, chemically stable, odorless and tasteless substance which safe for health and environment. The growth of processed food industry, increasing pharmaceutical and cosmetics production, and the growing oil drilling activities are the major factors driving the growth of CMC market. As a whole entrepreneur can venture in this field will be successful.
