Study of Deodorant Stones
Deodorant Stones are Natural
Key Points to Remember
1. Alum is a natural compound in nature, is present in the water we drink, in almost all the foods we eat, and in the air we breathe. According to a study conducted at the University of Wisconsin, the average American adult diet includes between 20 to 60 milligrams of alum per day, of which 20 to 50 milligrams come from FDA-approved food additives. Another 2 to 10 milligrams come from the natural content of the foods eaten.
2. In its natural form, alum is the third most abundant element in nature, after oxygen and silicon. It has been part of our environment since the beginning of time and is one of the basic building blocks of our universe. It makes up almost 8% of the earth's crust, surpassed in quantity only by oxygen at 47% and silicon at 28%. It is in soil and clays that only when processed produce metallic aluminum products.
3. Deodorant Stones feature physically large potassium or ammonium alum molecules and are not absorbed into the skin/blood. Water has a molecular weight of 18. A potassium alum crystal molecule has a molecular weight of 474.38. A potassium or ammonium alum crystal molecule, in solution, is hydrated 24 times and consequently has a molecular weight of 654. It is impossible through natural means to get water to permeate the skin. Witness the large number of moisturizers available at the cosmetic counter and imagine how difficult it would be for a molecule that weighs 36.3 times as much as water to permeate the skin.
4. The pH of the solution resulting from the topical application of potassium alum with perspiration is typically in the slightly acid range of 4 to 5.
