  • Applications

    Methyl 2-hydroxyethyl cellulose (CAS 9032-42-2) is primarily used as a thickener and rheology modifier in water-based systems, providing viscosity control and stabilization in coatings and printing inks; it also serves as a thickener and binder in cosmetics and personal care formulations such as creams, gels, shampoos, and toothpaste. In adhesives and sealants, it acts as a thickener and performance stabilizer; in household cleaning products, it functions as a thickener and texture enhancer to improve sag resistance and flow. In industrial manufacturing, it serves as a viscosity modifier and stabilizer in ceramic slurries and other aqueous formulations, and as a binder in certain plaster or cement-based products.
