FAQ
Frequently Asked Questions
Yes, food-grade carboxymethylcellulose (E466) is generally recognized as safe (GRAS) by regulatory bodies like the FDA and EFSA when used within specified limits.
CMC (carboxymethylcellulose) is specifically modified with carboxymethyl groups, giving it unique solubility and viscosity properties compared to other derivatives like methylcellulose or hydroxypropyl methylcellulose.
Yes, one of its key characteristics is its solubility in both hot and cold water, unlike some other cellulose ethers.
CMC stands for CarboxyMethyl Cellulose. The abbreviation is widely used in industry and academia for brevity, as the full name is long and technical.
A chemically modified cellulose derivative used as a thickening, stabilizing, or suspending agent in food, pharmaceuticals, and industrial products.
Carboxymethylcellulose is usually technical/scientific in register.
Carboxymethylcellulose: in British English it is pronounced /ˌkɑː.bɒk.si.ˌmeθ.əl.ˈsel.jʊ.ləʊz/, and in American English it is pronounced /ˌkɑːr.bɑːk.si.ˌmeθ.əl.ˈsel.jə.loʊs/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Think: CARBOXY (acid group) + METHYL (CH3 group) + CELLULOSE (from plants). It's a 'dressed-up' cellulose for industrial jobs.
Conceptual Metaphor
A CHEMICAL TOOLKIT: It is conceptualized as a multi-purpose additive that 'fixes' problems in mixtures (thickens, stabilizes, binds).
