Use

Potassium hydroxide is an inorganic compound with the formula KOH, and is commonly called caustic potash. It is used in various chemical, industrial, and manufacturing applications. Potassium Hydroxide is also a precursor to other potassium compounds. In food products, potassium hydroxide acts as a pH control agent, stabiliser, and food thickener. Potassium Hydroxide is available both in solid as liquid form.
