Alum Stone Ingredients

Alum stone is a natural cosmetic commonly used as a deodorant and aftershave. It is made from the naturally occurring mineral salt kalunite potassium alum. Potassium alum forms as encrustations on rocks near volcanic fumaroles. It appears as a translucent crystalline stone and is soluble in water. The formula is: K2SO4∙Al2(SO4)3∙24H2O

Alum stone has antimicrobial properties which allow it to prevent the growth of odor causing bacteria. It can also be used as an astringent and styptic. This inherent characteristic makes alum stone a highly effective deodorant and aftershave, as well as a cure for common razor bumps.

Since potassium alum, the active ingredient of alum stone, is soluble in water it leaves a fine, invisible layer on the skin’s surface when rubbed on the skin. Alum stone leaves no trace of the mineral salt, it can’t be seen, felt, or smelled, but it remains as an effective deodorant and aftershave.

Due to the highly effective nature of alum stone it has become a sought after natural product in many international markets. The high demand of alum stone has led to the chemical manufacturing and synthesizing of alum stone. Essentially this has led to the development of synthetic potassium alum, or otherwise known as Potash alum.
