Sodium hydroxide, also known as caustic soda, is a white solid used in various cosmetic products such as detergents, shaving products, depilatories, and skin care products.

It is mainly used as a pH regulator and has always been used for the saponification of fats and the production of soaps.

Caustic soda is also available on the market in the form of solutions at different concentrations. It is a widely exploited reagent both domestically and industrially, as well as being widely used in research laboratories of various types.

Although it can also be purchased by private individuals for domestic use, due to its danger, the use of caustic soda requires special precautions and knowledge.
