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.

Uses:
• Eye drops
• Shoes and other leather goods made outside the United States

Other names for phenylmercuric acetate:
• (Aceto) phenylmercury
• Acetoxyphenylmercury
• Mercury phenyl acetate
