Hydroxyethyl cellulose (HEC) is a white or light yellow, odorless, non-toxic powder. It is prepared from basic cellulose and ethylene oxide (or chloroethane) by etherification. It is a non-ionic soluble cellulose ether. Because HEC cellulose has good characteristics of thickening, suspension, dispersion, emulsification, adhesion, film formation, protection of moisture, and protection of colloids, it is widely used in petroleum extraction, coatings, construction, medicine and food, textiles, papermaking, and other fields.
1. Hydroxyethyl cellulose powder can be dissolved in hot and cold water, and will not precipitate when heated or boiled. Because of that, it has a wide range of solubility and viscosity characteristics and non-thermogelability.
2. HEC can coexist with other water-soluble polymers, surfactants, and salts. HEC is an excellent colloidal thickener containing high-concentration dielectric solutions.
3. Its water retention capacity is twice as high as that of methylcellulose, and it has good flow regulation.
4. Compared to methylcellulose and hydroxypropylmethylcellulose, HEC has the strongest protective colloid ability.
