hydroxyethyl cellulose cas number

Hydroxyethyl cellulose (HEC) is a versatile cellulose ether that has gained significant attention across various industries due to its unique properties and wide range of applications. With a CAS number of 9004-62-0, HEC is synthesized through the hydroxyethylation of cellulose, which involves the substitution of hydroxyl groups on the cellulose polymer chain with hydroxyethyl groups.

One of the most notable characteristics of hydroxyethyl cellulose is its excellent water-solubility, which enables it to function effectively as a thickening, suspending, and emulsifying agent. This property makes HEC an essential ingredient in preparing various aqueous solutions, such as coatings, adhesives, and personal care products. In the cosmetic and personal care sectors, for instance, HEC is commonly found in lotions, shampoos, and gels, where it enhances texture and provides a smooth application.

In the construction industry, hydroxyethyl cellulose acts as a valuable additive in cement-based products. It improves workability and provides better water retention during the curing process. As a result, HEC leads to enhanced durability and performance of construction materials like mortars and plasters. Its ability to retain moisture is particularly beneficial in reducing cracking and shrinkage, making it a preferred choice for construction professionals.

In the pharmaceutical industry, HEC serves as a crucial component in drug formulation. Its film-forming abilities allow HEC to be used in controlled-release formulations, ensuring that medications are delivered in a steady manner over time. Furthermore, its thickening and emulsifying properties help stabilize formulations, enhancing the bioavailability of active pharmaceutical ingredients.

The food industry also leverages hydroxyethyl cellulose due to its emulsifying and gelling properties, contributing to the texture and stability of various products, including sauces and dressings. HEC is recognized as a food additive, often referred to by its E number, E466, and is considered safe for consumption.

Innovation and research continue to expand the applications of hydroxyethyl cellulose. Ongoing studies are exploring its potential in bioengineering and regenerative medicine, where HEC could play a role in developing scaffolds for tissue engineering due to its biocompatibility and biodegradability.

In summary, hydroxyethyl cellulose, with its CAS number 9004-62-0, is a multifunctional compound that enhances the properties of numerous products in diverse industries. Its unique attributes make it an indispensable ingredient in formulations ranging from personal care products to construction materials, food items, and pharmaceuticals, solidifying its place as a vital component in modern manufacturing processes.
