Not An Allergen … maybe

Stainless Steel Water Bottle

Nickel has been the number one contact allergen for years, was the 2008 Allergen of the Year of the American Contact Dermatitis Society, and is everywhere. When we say that a stainless steel water bottle is probably not a contact allergen, we assume that it is a pretty plain, straightforward bottle (no chrome or nickel finish) and of very high-quality stainless steel. In very high-quality metals, the nickel is bonded very well. This significantly reduces the chances of the nickel being rubbed off. This is important because nickel is dissolved by sweat (a “microbial corrosion”), resulting in its absorption and penetration into the skin, which is what causes the allergic reaction.

“Not an allergen” also assumes that the stainless steel water bottle in question (and its cap, handle and other accessories) is uncolored, has no colored print, and is not wrapped in rubber or a rubberized plastic.

If you’ve patch tested positive for nickel, try using a nickel and cobalt spot test on the water bottle you’re considering, especially on the surfaces where you’ll be holding it the most and sipping from it. There are also new barrier creams that block nickel and cobalt ions, but check the ingredients list: while most are fragrance-free, some contain preservatives.

If you have a history of sensitive skin…

…don’t guess! Random trial and error can cause more damage. Ask your dermatologist about a patch test.

Regularly published reports on the most common allergens by the North American Contact Dermatitis Group and European Surveillance System on Contact Allergies (based on over 28,000 patch test results, combined), plus other studies. Remember, we are all individuals — just because an ingredient is not on the most common allergen lists does not mean you cannot be sensitive to it, or that it will not become an allergen. These references, being based on so many patch test results, are a good basis but it is always best to get a patch test yourself.
