The Science Behind Mineral Salt Deodorants
Perhaps you’ve got doubts about so-called liquid ‘crystal’ deodorants. But these mineral-based deodorants are anything but farfetched. The effectiveness of their ingredients is rooted in hard science, and these all-natural deodorants provide long-lasting protection against odor.
“Sweat is not inherently funky. Sweaty armpits smell awful because of odor-producing bacteria that live on your skin,” explains Kristien Boyle, a nationally-certified acupuncturist and herbalist. “The minerals in natural deodorants chemically neutralize the growth of such bacteria and their smelly side effects. Conventional personal care products achieve this effect through manmade chemicals.”
Here’s the lowdown on three different minerals often used in natural roll-on deodorants:
Zinc Citrate: Zinc citrate is a natural mineral found in the earth; it’s used in several different types of natural health products, including toothpaste and deodorant. As an ingredient in crystal deodorant, zinc citrate halts the growth of odor-causing bacteria on the skin. It’s one of the primary ingredients in Tom’s of Maine’s Natural Confidence Deodorant Crystal, which is clinically proven to provide 24 hours of odor protection.
Potassium Alum: Potassium alum is a mineral often used in natural personal care products. This mineral is typically found on rocks that contain sulfide and potassium minerals. When used as an ingredient in crystal deodorant, potassium alum inhibits the growth of smelly bacteria.
Zinc Ricinoleate: Created through a combination of zinc oxide and a purified fatty acid from castor seed oil, zinc salts of ricinoleic acid are highly effective at eliminating and preventing odors. This mineral binds to molecules of stinky armpit odors, rendering the scent neutral. The effectiveness of this natural process makes zinc ricinoleate a superior ingredient for natural deodorants.
