What is it?
Phenylmercuric acetate is a preservative previously used in personal care products, shoe and leather goods, as well as in herbicides
and fungicides. Its use in products is largely banned in the EU and severely restricted in the U.S., but may still be used in products
made in other parts of the world.
How can I avoid it?
Skin contact with phenylmercuric acetate is required for it to cause a rash. Discontinuation of exposure to products containing
phenylmercuric acetate 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 call the company directly.
At work, request a safety data sheet (SDS) to help identify potential sources of exposure.
