Not An Allergen.
Allergic sensitivity to aluminum chlorohydrate is very rare, which is why it is not on published lists of common allergens. This is impressive considering how much exposure we have to aluminum chlorohydrate (exposure can tend to increase the likelihood of an ingredient becoming allergenic). Deodorants and antiperspirants can cause redness, rashes, itching, burning, and allergic contact dermatitis, but rarely are these problems caused by aluminum chlorohydrate — most reactions are due to the common skin allergens that can be present in formulations, such as fragrances, masking fragrances, certain natural extracts, dyes, parabens or other preservatives.
Another popular ingredient in antiperspirants is aluminum zirconium. While also not a common allergen, it has been known to cause granulomas (bumps).
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.
