Dioctyl Adipate (DOA) is a plasticizer. DOA is a diester of adipic acid and two equivalents of n-octanol. Its chemical formula is C22H42O4.



  • Adipic Acid Esters are used as low-temperature-resistant and low-viscosity plasticizer for PVC and its copolymers and cellulose esters e.g. cellulose acetate butyrates and cellulose propionates.
  • They are used as solvent carriers or coupling agents for polyurethane and photographic films.
  • Lower chain esters of adipic acid are used as high-boiling, biodegradable, low-toxicity solvents and antiperspirants.
  • Longer chain esters are used as lubricants offering stable lubricity, corrosion protection, biodegradability, and performance properties at both high and low temperatures.


  • It has several advantages over some other plasticizers in that it is more economical.
  • It provides the desired changes to physical and mechanical properties without causing changes to the chemical structure of the polymer.
  • It jellifies quickly; in lacquer applications it serves to eliminate cracks, increase resistance and provide a smooth surface.
