Dioctyl adipate (DOA) is an organic compound with the formula (CH2CH2CO2C8H17)2. It is a colorless oily liquid . As well as related diesters derived from 2-ethylhexanol, decanol, isodecanol, etc., it is used as a plasticizer.[2][3]

DEHA is sometimes incorrectly called dioctyl adipate. The abbreviation DOA has also been used for bis(2-ethylhexyl) adipate (CAS # 103-23-1).

Toxicity

Esters of adipic acid exhibit low acute toxicities in animal models. The LD50 of the related ethylhexanoate is estimated at 900 mg/kg (rat, i.v.).[2]
