Bis(2-ethylhexyl) adipate or DEHA is a plasticizer. DEHA is an ester of 2-ethylhexanol and adipic acid. Its chemical formula is C22H42O4.
DEHA is sometimes called "dioctyl adipate", incorrectly. Other names include diisooctyl adipate and di(2-ethylhexyl) adipate.
DEHA is used as a functional hydraulic fluid, and a component of aircraft lubricants. It is sometimes also used as an ingredient in PVC-based plastic wrap.
DEHA has been demonstrated to induce liver adenomas and carcinomas in mice but not in rats. According to the International Agency for Research on Cancer (IARC), it is "not classifiable as to its carcinogenicity to humans (Group 3),"[1] suggesting inadequate evidence of human carcinogenicity.[2] While once on a U.S. Environmental Protection Agency list of toxic chemicals under the Emergency Planning and Community Right-to-Know Act, it has been removed because it "cannot be reasonably anticipated to cause [...] irreversible chronic health effects."[3]
