Santoflex™ 44PD is an amine based antioxidant particularly effective for gasolines produced by cracking or pyrolysis (high olefin content gasoline).


  • Santoflex™ 44PD is used as an antioxidant and sweetening agent for fuels at a level of 5-100 ppm active material.
  • When used in gasolines and gasoline formulations containing oxygenates, Santoflex™ 44PD reduces gum formation by inhibiting the oxidation of the olefins present in the fuel.
  • Santoflex™ 44PD is also effective at preventing oxidation of gasolines manufactured through pyrolysis.
