Chloro Alkali or Basic Chemical
Caustic soda is used in the manufacture of plastic wrap, soap and paper and is the major ingredient in most oven cleaners and liquid drain cleaners. In chemical manufacturing, it is used in chemical processing, oil refining and water treatment. Commercially, Caustic is generally used as either a solid, a 50-percent aqueous solution. Caustic soda should be used with caution, as it is an alkaline corrosive that can be hazardous. When it reacts with moisture in the air, it dissolves, generating heat. This heat may cause nearby flammable materials to ignite, resulting in a fire. It should be safely stored in a dry, cool and well-ventilated place, away from oxidizing or organic materials. It should not be allowed to come into contact with metal powders or acids.
