Basic information

Bleaching powder extract has a strong sterilization, disinfection, purification and bleaching effect, and has a wide range of applications in wool washing, textile, carpet, paper and other industries. Mainly by the reaction of calcium hypochlorite with water and carbon dioxide to generate hypochlorous acid with strong oxidation. Eliminate stains by hypochlorous acid. White powder or granules.
