DEHA [Di(2-ethylhexyl) adipate]

EPA Maximum Contaminant Level (MCL)

0.4 mg/L

DEHA [Di(2-ethylhexyl) adipate] is an organic chemical used as a lubricant, for hydraulic fluids, and as a plasticizer in a number of products and industries. According to the EPA, it's used in many domestic products: “bath oils, eye shadow, cologne, foundations, rouge, blusher, nail polish remover, moisturizers and indoor tanning preparations.”

DEHA can end up in foods like cheeses through packaging that has been plasticized with it. It arrives in water generally as discharge from factories.
