Hydroxyethyl cellulose (HEC) is a white or light yellow, odorless, non-toxic fibrous or powdered solid. It is prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chloroethanol), and belongs to non-ionic soluble cellulose ethers. Due to its good thickening, suspension, dispersion, emulsification, adhesion, film formation, moisture protection and protective colloid properties, HEC has been widely used in oil extraction, coatings, construction, medicine and food, textiles, papermaking and polymer polymerization. 40 mesh sieving rate ≥99%.

HEC (hydroxyethyl cellulose) has the following characteristics:
1. Physical properties: HEC is a white or light yellow fibrous or powdered solid, odorless and non-toxic.
2. Chemical properties: It is prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chloroethanol), and belongs to non-ionic soluble cellulose ethers.
3. Functional properties:
It has good thickening, suspension, dispersion, emulsification, adhesion, film formation, moisture protection and colloid protection.
It can be dissolved in cold water to form a transparent viscous solution, and the dissolution is not affected by pH value.
It has adsorption, surface activity, moisture retention and salt resistance.
These properties make HEC widely used in many fields, such as oil extraction, coatings, construction, medicine and food, textiles, papermaking and polymer polymerization.
