Chemical nature of dioctyle phthalate (DOP)

Dioctyl phthalate (DOP) is a clear, colourless liquid which is slightly more dense than water with a slight but characteristic odour. It is miscible with most organic solvents but not soluble in water.

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.
