Natural Sodium Sulphonate


Petadd EM MW-420 is a low molecular weight, natural sodium sulphonate. It provides good emulsification (permitting the blending of oils within water-based systems) and anti-corrosion properties, whilst also functioning as a co-solvent and binding agent.


  • Widely used within the metal-working, automotive, marine and mining industries.
  • It will keep water from metals parts and is therefore a good rust/corrosion inhibitor.
