Hydroxyethyl cellulose ether(9004-62-0)

Hydroxyethyl cellulose ether, with the chemical formula (C6H10O5)n·(C2H6O)n, is a water-soluble polymer derived from cellulose. It is commonly referred to as hydroxyethylcellulose (HEC). The CAS registry number for hydroxyethyl cellulose is 9004-62-0.

HEC is produced by reacting alkali cellulose with ethylene oxide under controlled conditions. The resulting product is a white to off-white, odorless, and tasteless powder that is soluble in both cold and hot water. HEC is used in various industries for its thickening, stabilizing, and film-forming properties. Some common applications of HEC include:

1. Personal Care Products: HEC is used in shampoos, conditioners, lotions, creams, and other personal care items as a thickening agent, stabilizer, and binder.
2. Pharmaceuticals: In pharmaceutical formulations, HEC serves as a thickening agent in oral liquids, a binder in tablet formulations, and a stabilizer in suspensions.
3. Construction Materials: HEC is added to construction materials such as tile adhesives, cement renders, and gypsum-based plasters to improve workability and water retention.
4. Paints and Coatings: HEC is used as a rheology modifier and thickener in water-based paints, coatings, and adhesives to control viscosity and enhance application properties.
5. Food Products: HEC is employed in food applications such as sauces, dressings, and desserts as a thickening and stabilizing agent.

HEC is valued for its versatility, compatibility with other ingredients, and ease of use in various formulations. It contributes to the texture, stability, and performance of products across different industries.
