![]() There has been only one study specifically assessing the risk of developing AD with the use of aluminum-containing deodorants. 4 However, this review evaluated oral, topical, and environmental exposure. A recent review of 46 studies looking at aluminum exposure and risk of developing AD concluded that aluminum is, in fact, a risk factor for the development of disease. In addition to these concerns, aluminum exposure from deodorant use has been blamed for the rising incidence of Alzheimer's Disease (AD). Numerous studies supporting 2 and discrediting 3 this claim have been published, but recently the FDA and the National Cancer Institute have stated that antiperspirants and deodorants are not linked to cancer. However, these products have received much attention as the possible cause of increasing rates of breast cancer, with most hypotheses indicating the estrogenic properties of parabens as the main contributing factor. ![]() Although no research has been published evaluating the mechanism of action of these products, the company that markets them, Crystal Body Deodorant (French Transit, Ltd., Burlingame, California), claims that the mineral salts create an environment in which bacteria cannot survive.Īntiperspirants and deodorants are generally very safe products. The consumer is instructed to wet the crystal and apply the product to the underarm area to prevent odor. These products are sold in solid crystal form. 1 Recently, naturally occurring zeolite minerals, in the form of potassium alum or ammonium alum crystals, have been marketed as all-natural alternatives to deodorants and antiperspirants. 1 Deodorants work by two different mechanisms-antimicrobial agents decrease the number of bacteria that produce volatile odoriferous substances and fragrances cover any odors that are produced. The active ingredient in antiperspirants is usually aluminum based, which reduces sweat by causing obstruction of the eccrine glands. While deodorants are considered cosmetic products because they do not change the function of the skin, antiperspirants are classified as drugs and are therefore subject to rules and regulations set forth by the Food and Drug Administration (FDA). These two activities are often combined into single products. Deodorants are used to mask odor whereas, antiperspirants are used to reduce the amount of sweat produced. ![]() Deodorants and antiperspirants are two of the most commonly used cosmetic products, with millions of consumers applying these products to their axilla everyday.
