Caustic Potash, also known as Potassium Hydroxide (KOH), is a highly caustic metallic base and alkali salt which is widely used in industry. It is a white, water-soluble solid that readily absorbs moisture from the air, forming a thick paste. Caustic potash is used in a variety of industrial and commercial applications, such as in the manufacturing of soap, detergents, textiles, and paper. It is also used in the production of fertilizers, glass, rubber, and other products. Due to its corrosive and caustic properties, caustic potash should be handled with extreme caution.
