Potassium Hydroxide

Potassium hydroxide is an inorganic compound with the formula KOH, and is commonly called caustic potash. Along with sodium hydroxide (NaOH), this colorless solid is a prototypical strong base. It has many industrial and niche applications, most of which exploit its corrosive nature and its reactivity toward acids.

KOH is noteworthy as the precursor to most soft and liquid soaps, as well as numerous potassium-containing chemicals.

Potassium Hydroxide is used in cosmetics diluted as a buffer to increase the alkalinity of an ingredient or product that has a very low pH and to manufacture liquid soaps. True liquid soap is only made using Potassium Hydroxide and fats for liquid soaps.

In the manufacturing of liquid soaps, potassium hydroxide in the presence of fats (oils and butters) reacts in a process commonly known as saponification to create a salt also known as soap.
