DOA plasticizer (dioctyl adipate) is a phthalate-free plasticizer for PVC. It is known for keeping its flexibility in the cold; it is used alone or together with DOTP in plastisol, artificial leather, cables and coatings. This article summarises what DOA is and how it differs from DOTP.

What is DOA?
DOA is the abbreviation of dioctyl adipate. Its chemical name is bis(2-ethylhexyl) adipate; it is also called DEHA. It is an adipate-based, oily, colourless liquid. It softens PVC and is chosen especially where the product should stay flexible at low temperature. It contains no phthalate.
Where is it used?
- PVC plastisol (together with DOTP or on its own)
- Artificial leather and coated fabrics
- Cables and cable jackets
- Hoses, gaskets and profiles
- PVC gloves and dip coating
- Soft PVC products intended for cold conditions
The difference between DOA and DOTP
Both are phthalate-free plasticizers. DOTP is general-purpose; DOA stands out where cold flexibility matters. They are often used together; the suitable ratio is set according to the product. For DOTP itself, see our article What Is DOTP Plasticizer?.
