We absorb just under five pounds of chemicals through our skin each year in the form of creams, lotions, sprays, deodorants and antiperspirants. And though the alleged link between aluminum-containing antiperspirants and Alzheimer's has long been in the public consciousness, many of the so-called "natural" (supposedly chemical-free) deodorants are startlingly far from non-toxic. Terra Naturals' Zemea, a corn-based aluminum- and petroleum-free deodorant launched this week, begs the question: Is it possible to obliterate body odour and be good to the planet?
50
Percentage of natural deodorants that contain petroleum-based propylene glycol - also known as antifreeze in 100-per-cent concentrations. It is extremely toxic to aquatic life.
57
Percentage of U.S. streams surveyed that contained triclosan, an antibacterial found in deodorants and soaps, which washes down the drains and into waterways when we shower. This has scientists worried because of triclosan's ability to kill the "good" bacteria that fight germs, resulting in concerns over rising antibacterial resistance.
90
Percentage of breast tumours in a 2004 British study found to contain parabens, a common deodorant and antiperspirant ingredient. While the study remains controversial (no control group was tested), researchers state that parabens have been known to mimic the effects of estrogen, which can promote cancerous tumour growth in the breasts.
3,000
Estimated number of tigers in India, down from 20,000, because of the illegal mining of talc, which has threatened their habitat in the Jamwa Ramgarh Wildlife Sanctuary and the neighbouring Sariska Tiger Reserve. Talc, though a natural ingredient, is common to drugstore deodorants (and is also a key ingredient in baby powder). Talc is closely related to the potent carcinogen asbestos and can be carcinogenic if contaminated with arsenic. Talc particles have been shown to cause cancerous tumours in the ovaries and lungs.
BOTTOM LINE
It's hard not to glaze over when considering the sea of scent-prevention products. But a position on the health-food store shelf doesn't necessarily equal chemical-free - some natural crystal deodorants actually contain potassium alum, a form of aluminum. Deodorants, considered cosmetics by Health Canada, have "no regulations specifying good manufacturing processes," but have recently been legislated to list ingredients, so it's imperative to check labelling. Avoid antiperspirants entirely, and if after reading the label you find no mention of parabens, talc or propylene glycol, you're on the right track. You might have to arrange for emergency reapplications throughout the day, but it beats the environmental price of coming clean.
