Amyl Cinnamaldehyde

Skin contact with amyl cinnamaldehyde is required for it to cause a rash. Discontinuation of exposure to products containing amyl cinnamaldehyde 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 amyl cinnamaldehyde can be difficult, since so many everyday products contain these substances. One should use only fragrance-free cosmetic and household products. “Unscented” products may contain low levels of a fragrance to cover up an undesirable odor and also should be avoided. Products labeled as “hypoallergenic” do not assure that the product is truly free of fragrance.

Although it is rare, since some fragrances are also flavors, foods that contain them can sometimes cause flare-ups of dermatitis in fragrance-sensitive individuals. If your healthcare provider has diagnosed that you have oral or lip allergies, it would be best to avoid foods prepared with cinnamon.
