Abstract: The protective efficiency of a formulation based on low erucic colza oil against carbon steel corrosion in salt solution (0.5 M NaCl), in a thermal moisture chamber and under natural conditions has been studied. The following formulations have been used: (1) colza oil (CO) without inhibiting additives; (2) CO with addition (1–10 wt.%) of synthetic fat acids bottoms (SFAB); and (3) CO with the IFHAN-29A anticorrosion additive (20 wt.%). Corrosion tests and electrochemical measurements have been conducted. Protective CO coatings are not efficient in the presence of chloride ions but provide a high protective efficiency under natural conditions.
