Hydroxyethyl Cellulose CAS# 9004-62-0
Hydroxyethyl cellulose is a commonly used cellulose ether organic water-based ink thickener. It is a water-soluble non-ionic compound. It has good thickening ability for water and can be degraded by oxygen, acid and enzyme. It can be cross-linked by Cu2+ under chemical conditions. It is stable to heat, does not gel when heated, does not precipitate under acidic conditions, and has good film-forming properties. Its aqueous solution can be made into a transparent film, which can be formed by the interaction of alkaline cellulose and ethylene oxide.
