Potassium Hydroxide is extremely corrosive and can be a hazardous irritant when exposure is at high levels. According to its Material Safety Data Sheet, it "May cause irritation. ... Potassium hydroxide is corrosive! Contact of skin can cause irritation or severe burns and scarring with greater exposures."
Potassium hydroxide, or caustic potash, is used in a wide variety of industrial applications. The major uses are in the production of potassium carbonate,potassium phosphates, liquid fertilizers, and potassium soaps and detergents.
