What is it?
Peppermint oil is used as a fragrance in personal care products and as a flavoring in foods.
How can I avoid it?
Skin contact with peppermint oil is required for it to cause a rash. Discontinuation of exposure to products containing peppermint
oil should result in improvement and/or resolution of your dermatitis. By law, all products made in the U.S. for topical use have the
ingredients listed either on the product package or the box that contains it, so check the labeling of your skincare products for this
ingredient. If there is not enough information, ask your pharmacist or retailer, or contact the company directly. At work, request a
Safety Data Sheet (SDS) to help identify potential sources of exposure.
The avoidance of fragrances and flavoring agents such as peppermint oil can be difficult, since so many everyday products contain
these substances. Individuals allergic to peppermint oil often have sensitivity to other fragrances and flavorings, so it is recommended
that you should use only fragrance-free cosmetic and household products. “Unscented” products may contain low levels of a fragrance
to cover up an undesirable odor, so these should also be avoided. Products labeled as “hypoallergenic” do not assure that the product
is truly free of fragrance.
Direct contact with foods or products containing peppermint oil may cause symptoms, including burning, irritation, and redness.
Direct contact may occur on the skin, lips, or mouth. Although it is rare, since some fragrances are also flavors, foods that contain
peppermint oil can cause flare-ups of dermatitis in fragrance-sensitive individuals. If your healthcare provider has diagnosed you
with oral or lip allergies to fragrances or flavorings, you should avoid foods prepared with peppermint oil.
