  • Applications

    Cellulose, hydroxybutyl methyl ether is a water-soluble cellulose ether used as a thickener, stabilizer and rheology modifier in a range of formulations. In cosmetics and personal care, it provides viscosity and helps suspend pigments and active ingredients in creams, lotions and hair-care products. In coatings, inks and paints, it controls flow, sag resistance and film formation. In adhesives and sealants, it acts as a thickener and texture enhancer to improve processability. In household and cleaning products, it offers viscosity control, helps suspend solids and stabilizes formulations. In industrial manufacturing, it serves as a rheology modifier in polymer formulations, detergents and other process formulations, with use governed by formulation limits and local regulations.
