DEHA is sometimes called "dioctyl adipate", incorrectly. Another name is di(2-ethylhexyl) adipate.
Use
As well as related diesters derived from octanol, decanol, isodecanol, etc., it is used as a plasticizer.[1]
DEHA is used as a hydraulic fluid, and a component of aircraft lubricants. It is sometimes also used as an ingredient in PVC-based plastic wrap.
Toxicity
DEHA has very low toxicity. The LD50 is estimated at 900 mg/kg (rat, i.v.).[1]
According to the International Agency for Research on Cancer (IARC), it is "not classifiable as to its carcinogenicity to humans (Group 3)."[2][3]
