Potash lye / potassium hydroxide / KOH 40 %

The 50% potassium hydroxide solution is a highly concentrated, strong alkaline solution used in various areas of the laboratory and industry. Due to its high concentration, it is particularly effective in applications that require a strong alkaline reaction.

In the chemical industry, the 40% potash solution is used in the manufacture of soaps and detergents, as it provides a strong alkalinity for these processes. In the textile industry it can be used to remove grease and dirt, while in the food industry it is used to regulate pH and as a preservative. However, due to its high concentration, care must be taken as it is highly corrosive.

In the laboratory, 40% caustic potash is used as an etchant to remove proteins and grease from glassware or to neutralize acids. In industry, it is used for anisotropic etching of silicon and as an electrolyte. In addition, potassium hydroxide is used as an etching additive in metallography to make certain structures in metals visible. The high concentration of the solution leads to a more effective etching reaction and better structure representation.
