  • Applications

    Isomalt (CAS 64519-82-0) is used as a low-calorie sweetener in foods, particularly in confectionery such as hard candies, chews, and chocolates, where its resistance to crystallization and heat stability help maintain texture in sugar-free products; it also serves as an excipient, filler, or binder in pharmaceuticals to aid formulation and mouthfeel; in cosmetics and personal care, it can function as a humectant and texture enhancer; it may also be evaluated for use as a processing aid and stabilizer in other industrial formulations.
