Hydroxyethyl Cellulose (HEC): The Standard in Rheology Control

Hydroxyethyl Cellulose (HEC) is a non-ionic, water-soluble polymer derived from natural cellulose. As a leading cellulose ether, HEC is engineered to perform as a high-efficiency thickener, water-retention agent, and stabilizer in a vast array of aqueous systems.

Its key distinction is its non-ionic character. Unlike anionic polymers such as Carboxymethyl Cellulose (CMC) or Polyanionic Cellulose (PAC), HEC does not carry an ionic charge in solution. This makes it exceptionally stable and functional across a wide pH range and in formulations with high concentrations of electrolytes (salts), making it the ultimate rheology modifier for complex systems.
