Hydroxyethyl cellulose(CAS: 9004-62-0)

Hydroxyethyl cellulose (HEC), with the CAS number 9004-62-0, is a water-soluble polymer derived from cellulose. It has the chemical formula [C6H7O2(COOC2H4OH)n] and is characterized by its high viscosity, stability, and film-forming properties. HEC is commonly used as a thickening agent and binder in various applications due to its compatibility with water and organic solvents.

Hydroxyethyl cellulose (HEC) is widely used in pharmaceuticals as a binder and thickener in tablets and capsules. In the food industry, it serves as a stabilizer and emulsifier in products like dairy and beverages. It also finds application in cosmetics, adhesives, and construction materials. Additionally, HEC is used in research for its ability to form gels and suspensions in aqueous solutions.

Hydroxyethyl cellulose (HEC) is generally considered safe when used as per recommended guidelines. It is non-toxic and has low irritancy, making it suitable for many consumer and industrial applications. However, proper handling and protective measures, such as gloves and goggles, should be taken during its use to ensure safety. Safety standards are well-established for its use in food, pharmaceuticals, and cosmetics.

Hydroxyethyl cellulose (HEC) should be stored in a cool, dry place away from direct sunlight. It is stable under normal storage conditions and typically requires a storage temperature between 15°C to 25°C. Maintaining low humidity is essential to prevent clumping, and it should be kept in airtight containers to avoid moisture absorption and contamination.
