  • Applications

    Sodium mannuronate methylsilanol (CAS 23732-95-8) is commonly evaluated as a rheology modifier, thickener, and stabilizer in cosmetics and personal care, where its alginate-derived backbone provides controlled viscosity and texture without excessive gelling. It may act as a film-forming binder in skin and hair care formulations. In household cleaning and surface-care products, it can serve as a viscosity modifier and suspension aid, helping distribute solid particulates uniformly. In coatings and inks, as well as in certain polymer formulations, it functions as a stabilizer or binder that improves rheology, processability, and adhesion. In adhesives and sealants, it may act as a specialty additive contributing to compatibility and film formation. Overall, use is subject to local regulations and formulation limits.
