What is it?
Propyl gallate is a preservative. It is used in the food, pharmaceutical, and cosmetic industries as an antioxidant to prevent oils and fats from
becoming rancid.
How can I avoid it?
Skin contact with propyl gallate is required for it to cause a rash. Discontinuation of exposure to products containing propyl gallate 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.
Direct contact with foods or products containing propyl gallate may cause symptoms including burning, irritation, and redness. Direct contact
may occur on the skin, lips, or mouth. Although it is rare, it is possible that ingestion of propyl gallate could cause generalized symptoms such as itching or redness of the skin.
