ethyl cellulose
RareTechnical/Scientific
Definition
Meaning
A semi-synthetic polymer derived from cellulose where some of the hydroxyl groups are replaced with ethyl ether groups.
A non-toxic, water-insoluble compound used as a thickener, binder, film-former, and stabilizer in pharmaceuticals, foods, cosmetics, and various industrial applications.
Linguistics
Semantic Notes
A compound term where 'ethyl' refers to the specific chemical group and 'cellulose' refers to the base polysaccharide polymer. It is not a brand name but a specific chemical entity.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calques like *этил целлюлоза*. The correct translation is 'этилцеллюлоза' (one word).
- Do not confuse with 'methyl cellulose' (метилцеллюлоза), which has different solubility properties.
Common Mistakes
- Misspelling as 'ethyle cellulose' or 'ethylcellose'.
- Incorrect hyphenation (ethyl-cellulose).
- Mispronouncing 'cellulose' with stress on the first syllable.
