  • Applications

    Agar (CAS 9002-18-0) is a polysaccharide derived from red seaweed that is widely used as a gelling agent and stabilizer across multiple industries. In food processing, it forms firm, heat-stable gels suitable for jellies, puddings, and other gelled products; in pharmaceuticals and biomedical applications, it often serves as an excipient and gel matrix in certain formulations; in microbiology, agar is a standard solid culture medium for growing microorganisms in laboratories, enabling isolation and analysis of different strains. In cosmetics and personal care, agar is used as a thickener and stabilizer to increase viscosity and gel structure in products such as masks, creams, and cleansers. Applications may vary with local regulations and formulation limits.
