It is described a process for the production of plasticizer, which contains in the raffinate from purification of petroleum oil fractions with a selective solvent, and separation of the extract. The extract is treated with a polar solvent with a weight ratio of a polar solvent to the extract (2.0 to 4.0): 1 at temperature from 30 to 120 ø C. The plasticizer comprises the following ratio of components in the refined product: aromatic hydrocarbons 60-90% wt., of which polycyclic aromatic hydrocarbons with three or more rings is from 1 and 2.9% by weight. and up to 100%. paraffin-naphthenic hydrocarbons and resins. Opisuje sa spôsob výroby zmäkčovadla, ktoré obsahuje rafinát z čistenia petrolejových ropných frakcií so selektívnymi rozpúšťadlami a separáciu extraktu. Extrakt upravuje s polárnym rozpúšťadlom s hmotnostným pomerom polárneho rozpúšťadla k extraktu od (2,0 do 4,0) : 1 pri teplote od 30 do 120 °C. Zmäkčovadlo obsahuje nasledujúci pomer komponentov v rafináte : aromatické uhľovodíky 60 - 90 % hmotn., ktorých polycyklické aromatické uhľovodíky s tromi a viacerými cyklami predstavujú od 1 do 2,9 % hmotn. a do 100 % hmotn. parafíno-nafténové uhľovodíky a živice.
