Our deodorants are made from potassium alum. Alum is drawn from bauxite ore. Bauxite ore is formed by the rapid weathering of granite rocks in warm, humid climates and can be purified and converted directly into alum.
Unlike aluminum, alum is a salt. If an aluminum-metal compound, such as aluminum chlorohydrate, is used as an antiperspirant, that compound is readily absorbed. Once in the body, the aluminum portion of the molecule ionizes, forming free, radical aluminum in the blood. This passes freely across cell membranes and is randomly absorbed by the liver, kidney, brain, cartilage, and bone marrow with potentially serious health consequences.
Potassium alum molecules have a negative ionic charge, making them unable to pass through the cell walls. They are not absorbed into the body! All the effects alum exhibits on odor-causing bacteria remain on the skin?s surface, not in the blood. This is why our deodorants are safe for the body.
