Description
Introduction
Potassium Hydroxide (KOH), also known as caustic potash, is a strong alkaline compound with the chemical formula KOH. It is a white, odorless solid that readily dissolves in water, producing a highly alkaline solution. Potassium Hydroxide is industrially produced through the electrolysis of potassium chloride (KCl) solution. KOH is an extremely versatile inorganic compound widely utilized in various industrial and commercial applications. These white solid flakes possess strong basic or alkaline properties, opposite to acidity, with a pH of 13. Due to these attributes, potassium hydroxide finds extensive use in soap and cleaner production. It can be found in a wide range of products such as bath and cleaning goods, hair dyes and colors, cosmetics, nail products, personal hygiene items, shampoos, shaving products, depilatories, and skincare formulations.
