Bis(2-ethylhexyl) adipate or DEHA or DOA is an organic compound with the formula (CH ₂ CH ₂ CO ₂ C ₈ H ₁₇ ) ₂ . It is the diester of 2-ethylhexanol and adipic acid . It is a colorless oily liquid.

DEHA is sometimes called " dioctyl adipate ", incorrectly. Another name is di(2-ethylhexyl) adipate. The abbreviation DOA has been unfortunately 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 LD ₅₀ 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]}
