About GRINDSTED® Cellulose gum (CMC)

Cellulose gum is the generic name of highly purified carboxymethyl cellulose (CMC). This is obtained after purification of CMC.

CMC is usually used to describe non-purified or lowly purified carboxymethyl cellulose.

Both cellulose gum and CMC are based upon naturally occurring cellulose such as wood pulp and cotton fibres (Linters).

After etherification, purification and drying, a white to off-white, odourless, free flowing powder is obtained.

This powder is hydrophilic and water soluble.
Three purity levels can be achieved:

Cellulose gum for regulated industries (food grade, oral and personal care, pharmaceutical), assay from 97% min. to 99.5% min. depending on local regulations.
Semi-purified CMC, from 70% to 97%.
Technical (crude) CMC, below 70%.
