**I know this post is very long, but I really think it is important you read it- just skim some parts if you need to in order to get the gist of what I found...
Some of you may have heard about all the potential dangers of antiperspirants/deodorants. I heard a few things here and there, but not enough to really concern me. Since I've been doing research on this topic, I have found quite alarming facts that have lead me to change what I use.
First off, I want to explain that the law does not require manufacturers to test their products for safety. Many ingredients used in deodorants and other personal care products have not been fully tested, with the majority not tested at all. The industry, in an attempt to make it look like it's acting in the interest of consumer safety, formed the Cosmetic Ingredient Review in 1976 to evaluate the safety of ingredients used in cosmetics and personal care products. However, in the 29 years up to June 2005, they performed safety assessments on only about 10% of the ingredients allowed in cosmetic and personal care products, including deodorants, and never evaluated one third of the 50 most commonly used ingredients.
The main harmful ingredients that often show up in antiperspirants/deodorants are
aluminum, butane, propane, propylene glycol, talc, parabens (see previous posting for more info on these) and
phthalates* (see end of posting for all forms of phthalates in products).
www.productwarning.netHere are the ingredients itemized with explanation of why they raise concern:
-Propylene Glycol: Industrial Uses are
Anti-Freeze, Brake and Hydraulic Fluid, Paint, Floor Wax. Implicated in contact dermatitis, kidney damage and liver abnormalities; can inhibit cell growth in human tests and can damage membranes causing rashes, dry skin and surface damage. May be harmful by inhalation, ingestion or skin absorption. May cause eye irritation. Exposure can cause gastro-intestinal disturbances, nausea, headache and vomiting, central nervous system depression. (Material Safety Data Sheets, MSDS) Also causes significant number of reactions and was a primary irritant to the skin in low levels of concentrations. (American Academy of Dermatologists Inc, Jan 1991)
-Talc: A possible tie between talcum powder and ovarian cancer, long suspected because of talc's chemical similarity to asbestos, was strongly supported when a study found a higher risk of the cancer among women who used feminine deodorant sprays. The study, published in the American Journal of Epidemiology, found that women who used talcum powder in the genital area had an increased ovarian cancer risk of 60% and women who used feminine deodorant sprays had a 90% increased risk. In 1994, the FDA conducted a scientific workshop on the issue and did not find enough of a casual link to justify even a consumer warning.
-Aluminum: Aluminum is a metal, the third most common element in the environment and a toxin in the body. Found in processed foods, antiperspirants, antacids, paper products, beverage cans, foil and cookware.
World Health Organization conducts studies on chemical pollution and the elderly...
"There is a suspected link between Alzheimer's disease and the toxicity of aluminum... autopsies have found high concentrations of the metal in the brain of people who had suffered from the disease." (Public Health Reports, Nov-Dec 1993 v108n6p798(2)) Dr. Daniel Perl, Director of Neuropathology at Mount Sinai Medical Center in New York, suggests "...avoid aerosol antiperspirants. Aluminum in aerosol may be more readily absorbed into the brain through nasal passages."
"Aluminum-containing antiperspirants are designed to be absorbed, and studies show that regular use of these products can raise the risk of Alzheimer's by as much as three-fold. (also)...municipal water supplies treated with alum (aluminum sulfate)" (Natural Health, May-June 1993 v23n3p54(2))
-Butane: Banned in EU (European Union- Similar to our FDA, but way smarter and they actually care about their people) cosmetics for impurity limit. Lung sensitizer that can instigate immune system response that can include itching, burning, scaling, hives, and blistering of skin. It's on Canada's "Environmental Canada Domestic Substance List" because it is found to be carcinogenic to humans and genotoxic to humans (genotoxic=chemicals that are capable of causing damage to DNA, such damage can lead to formation of a tumor). (
Environmental Working Group)
-Propane: Skin irritant, lung sensitizer, neurotoxin, organ system toxicity, immunotoxicity. (EWG)
-Phthalates: Phthalates are known as "endocrine disruptors" because they mimic the body's hormones and have, in laboratory animal tests, been shown to cause reproductive and neurological damage. Can damage the liver, the kidneys, the lungs and the reproductive system, especially the developing testes. Studies have shown irritation of the eyes (lacrimation), skin, nose, throat; headache, dizziness, nausea; possible polyneuropathy, vestibular dysfunction, pain, numbness, weakness, exhaustion, spasms in arms and legs, reproductive effects in animals.(Congress approved a nationwide ban on the use of phthalates in toys and baby products made after Feb 2009.)

I did find a great natural deodorant from "
Benedetta". It works better than Tom's Natural Deodorant (not to mention the first listed ingredient is propylene glycol). I actually got a sample of Benedetta's deodorant from a booth at my local farmer's market and ended up loving it! It's a bit pricey, $15 for a 80ml bottle, but it will last a long time because it's a spray and doesn't take much at all. Another plus, it wont leave your dark clothing with a white mark, or your light shirts with yellow marks over time, like some other deodorants can do! Please let me know if you find a good one, too!

*Phthalates: Dibutyl phthalate(DBP), di 2 ethylhexyl phthalate, diethyl phthalate(DEP), Benzylbutyl phthalate(BzBP). "fragrance" can also denote a combination of compounds, possibly including phthatates. Some products denote "Phthalate Free" which helps, but still be weary of "fragrance".
