It usually appears as white flakes, pearls, or solid, with high solubility in water and strong corrosiveness. It is widely used in soap making, paper manufacturing, textile processing, water treatment, chemical synthesis, and cleaning industries. With stable quality and high purity, it serves as an essential raw material in industrial production, neutralizing acids, saponifying fats, and adjusting pH efficiently.
