stone alum is a great deodorant. It is used to neutralize perspiration, preventing fermentation and removing odors. Alum stone has the ability to inhibit the formation of malodorous bacteria on the skin. It can also be used as after shave thanks to its excellent ability to soften skin and stop bleeding.
Our stones are 100% natural alum.
No health hazard: The negative ionic charge of potassium alum and its particular molecular structure are that it can not be absorbed by the skin cells, which makes absolutely harmless, unlike other aluminum components sometimes used in conventional anti-perspirants.
