  • Applications

    Alginic acid, potassium salt (CAS 9005-36-1; also known as potassium alginate) is used as a thickener, gelling agent, and stabilizer in food processing, helping improve the texture of dairy products, sauces, and desserts; it is also employed as a thickener and stabilizer in cosmetics and personal care. In pharmaceuticals, it acts as an excipient and binder and can modify the rheology of suspensions and gels. In coatings and inks, potassium alginate serves as a thickener and stabilizer for formulations of coatings and inks. In paper and textile processing, it functions as a binder and thickener in related formulations. In agriculture, alginate can be used for encapsulation and controlled-release of agricultural actives in formulations.
