Methyl-Hydroxyethylcellulose | CAS 9032-42-2

Methyl Hydroxyethylcellulose (MHEC) is a cellulose derivative with the chemical formula (C6H10O5)n. It is derived from cellulose, a naturally occurring polymer found in the cell walls of plants. MHEC is synthesized through the chemical modification of cellulose, introducing both methyl and hydroxyethyl groups onto the cellulose backbone.

Here are some key points about Methyl Hydroxyethylcellulose:

1. Chemical Structure: MHEC is a water-soluble polymer with a structure similar to that of cellulose. The addition of methyl and hydroxyethyl groups imparts unique properties to the polymer, including improved solubility in water and enhanced thickening ability.
2. Properties: MHEC exhibits excellent thickening, film-forming, and binding properties, making it suitable for a wide range of applications. It is commonly used as a thickener, stabilizer, and viscosity modifier in various industries, including construction, pharmaceuticals, personal care, and coatings.
3. CAS Number: The CAS number for Methyl Hydroxyethylcellulose is 9032-42-2. CAS numbers are unique numerical identifiers assigned to chemical substances to facilitate identification and tracking in scientific literature and regulatory databases.
4. Applications: MHEC finds extensive use in the construction industry as a thickening agent in cement-based mortars, tile adhesives, and gypsum-based materials. In pharmaceuticals and personal care products, it is utilized as a binder, film former, and viscosity modifier in tablet coatings, ophthalmic solutions, creams, lotions, and shampoos.
5. Regulatory Status: Methyl Hydroxyethylcellulose is generally regarded as safe (GRAS) for its intended uses in various industries. However, specific regulatory requirements may vary depending on the country or region of use. It is essential to comply with relevant regulations and guidelines when formulating products containing MHEC.
