HEC
I
t is a white or light yellow, odorless, non -toxic fibrous or powdered solid prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chloroethanol), belonging to the non ionic soluble cellulose ether class. Due to its excellent thickening, suspension, dispersion, emulsification, adhesion, film formation, moisture protection, and provision of protective colloids, HEC has been widely used in fields such as petroleum exploration, coatings, construction, pharmaceuticals and food, textiles, papermaking, and polymer polymerization reactions.
The characteristics of HEC (Hydroxyethyl Cellulose) make it widely used in industrial fields:1. Water Solubility and Dissolution：It dissolves easily in both cold and hot water to form a transparent solution, requiring no high-temperature dissolution, which adapts to various production processes (e.g., direct addition in the cold blending process of daily chemicals).
2. Thickening and Rheology：It significantly increases the viscosity of the system at low concentrations and exhibits pseudoplasticity (shear thinning, restoring viscosity after shear force disappears), suitable for anti-sag in latex paint brushing and reducing resistance in drilling fluid pumping.
3. Stability：It is resistant to acid and alkali (stable in the pH range of 3-11), salt-resistant (usable in detergent with electrolytes or high-salt oilfield environments), and maintains solution properties at high temperatures (e.g., 100℃), suitable for high-temperature processes.
4. Film-Forming and Compatibility：It forms a flexible film after drying (e.g., water-based inks do not crack easily after drying) and has good compatibility with most surfactants and pigments (e.g., can be compounded with silicone oil and glycerin in cosmetics).
5. Environmental Protection and Safety：It is non-toxic and biodegradable (compliant with EU Cosmetic Regulation EC 1223/2009), and can be safely used in pharmaceutical and food contact fields (e.g., water-based adhesives for food packaging). Comparative Advantages：Compared with methylcellulose, HEC has better high-temperature resistance; compared with starch-based thickeners, it has stronger resistance to microbial degradation and a longer storage period.
