The deo-crystal is a 100% natural product, consisting of a number of mineral salts. Brought into contact with water and light, these crystallise over a period of weeks. There are no chemicals or other additives involved.
When applied, the crystal leaves an unnoticeable film of molecules on the skin. These aid the skin in its natural process of protection against the bacteria that are the cause of odour and discomfort. While the growth of bacteria is prevented, the skin is allowed to breathe. Also, the crystal neutralises the fat in perspiration, causing it to dry faster. Perspiration, in itself a natural and necessary process, is not hindered. There is no absorption of material into the skin because of the large molecular structure of the crystal, and there is no toxic residue. The deo-crystal will not irritate sensitive skin. Anybody can use it for any length of time.
Crystal Fresh is made from pure potassium mineral salts, and nothing else. Potassium Alum occurs naturally in such minerals as Alunite (alum stone), Bauxite and Kalinite.
The alum that is used in Crystal Fresh is in the salt form, not the metallic form. Alum is a natural element in nature, is present in the water we drink, in almost all the foods we eat and in the air we breathe.
The deodorant stone creates an environment hostile to bacterial growth. This is partially due to the low Ph of the deodorant and perspiration combination. No bacteria = no odour!
