Potassium hydroxide is alkaline, soluble in water and strongly corrosive. Dissolved in water gives off a lot of heat. Owing to the decomposition of carbohydrates by hydroxides, the risk of acid corrosion is more serious. The corroded skin usually presents deep burns and is difficult to heal. Once the eyes or skin contact, the injured part should be washed with water for more than 15 minutes, and immediately seek medical treatment. Oral treatment can burn the digestive tract, which can be fatal.
