hydroxyethyl cellulose cas number

Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose. It is widely used in various industries, including pharmaceuticals, cosmetics, and food production, owing to its unique properties. The chemical formula for hydroxyethyl cellulose is (C2H4O)n, and its CAS number is 9004-62-0. This makes it easily identifiable and searchable within chemical databases and regulatory frameworks.

In addition to its thickening abilities, hydroxyethyl cellulose also acts as a stabilizer and emulsifier. It plays a crucial role in preventing the separation of ingredients in various formulations, thereby ensuring product stability. This makes HEC an essential component in the cosmetic industry, where the stability of emulsions is vital for product integrity. Furthermore, its film-forming capacity allows for the creation of protective layers on the skin, making it popular in personal care products.

In the pharmaceutical sector, hydroxyethyl cellulose is utilized as a binder and disintegrant in tablet formulations. Its ability to swell upon contact with water aids in the disintegration of tablets, promoting the release of active pharmaceutical ingredients (APIs) in the body. This attribute contributes to the overall efficacy of medications, making HEC a critical component in drug development.

HEC is also used in food applications as a thickener and stabilizer. It enhances the texture and mouthfeel of various food products, including sauces, dressings, and dairy items. As a food additive, it is considered safe, and its use is regulated by food safety authorities in numerous countries.

In conclusion, hydroxyethyl cellulose (CAS number 9004-62-0) is a versatile polymer with a diverse range of applications. From pharmaceuticals to food products, its thickening, stabilizing, and emulsifying properties make it an invaluable ingredient across many industries. As research continues to evolve, the potential applications of HEC are likely to expand, reinforcing its significance in both existing and new fields.
