  • Applications

    Calcium sodium alginate (CAS 12698-40-7) is widely used as a thickening, gelling, and stabilizing agent across multiple industries. In food processing, it acts as a gelling agent and texture modifier for dairy, desserts, and sauces. In cosmetics and personal care, it provides viscosity control and a soft gel feel in creams, gels, and cleansers. In pharmaceutical formulations, it serves as an excipient for controlled-release matrices and as a gel-forming binder in tablets and suspensions. In industrial manufacturing, it functions as a thickener and stabilizer in coatings, inks, and adhesive formulations, improving suspension stability and film formation. In agriculture, it is evaluated for encapsulation and slow-release delivery of agrochemicals and nutrients.
