Bis(2-ethylhexyl) adipate or DEHA is an organic compound with the formula (CH2CH2CO2C8H17)2. It is the diester of 2-ethylhexanol and adipic acid. It is a colorless oily liquid.
DEHA is sometimes called "dioctyl adipate" or DOA, incorrectly. Another name is di(2-ethylhexyl) adipate. The abbreviation DOA has been used for both bis(-2-ethylhexyl)-adipate and dioctyl adipate
Use
[edit ]As well as related diesters derived from octanol, decanol, isodecanol, etc., it is used as a plasticizer.[3]
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
[edit ]DEHA has very low toxicity. The LD50 is estimated at 900 mg/kg (rat, i.v.).[3]
According to the International Agency for Research on Cancer (IARC), it is "not classifiable as to its carcinogenicity to humans (Group 3)."[4] [5]
