Monoethanolamine (MEA)

Monoethanolamine is primarily used as an emulsifier in a variety of products including detergents, polishes, and corrosion inhibitors.  It can also be used as an additive to some pharmaceuticals (e.g., antidepressants and antihistamines).

Skin contact with monoethanolamine is required for it to cause a rash. Discontinuation of exposure to products containing monoethanolamine 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 skin care 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.
