Dioctyl adipate or DOA is a plasticizer

Plasticizer

Plasticizers or dispersants are additives that increase the plasticity or fluidity of the material to which they are added; these include plastics, cement, concrete, wallboard, and clay. Although the same compounds are often used for both plastics and concretes the desired effects and results are...

DEHA

Bis(2-ethylhexyl) adipate

Bis adipate or DEHA is a plasticizer. DEHA is an ester of 2-ethylhexanol and adipic acid. Its chemical formula is 22424.DEHA is sometimes called "dioctyl adipate", incorrectly. Other names include diisooctyl adipate and di adipate.-Use:DEHA is used as a functional hydraulic fluid, and a component...

Ester

Esters are chemical compounds derived by reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH group is replaced by an -O-alkyl group, and most commonly from carboxylic acids and...
