Main purpose
Bropol is mainly used as a preservative and bactericide. It is added during the processing of cosmetics such as shampoos, balms and creams. Its concentration in cosmetics is 0.01% - 0.02%. It can also be used in detergents, fabric treatment agents, etc. As a bactericide. It can effectively prevent various plant pathogenic bacteria. When used for treating cotton seeds, it can prevent cotton black arm disease caused by cotton spot fungus and bacterial blight, without causing harm to cotton. It can also be used for rice blight disease. The recommended concentration is 800 - 1000 mg/L. It is also used in industrial circulating water, paper pulp, coatings, plastics, cosmetics, wood, cooling water circulation systems, as well as for sterilization, mold prevention, preservation, and algae elimination in industrial applications.
