ABSTRACT:
The present invention comprises a process for improving the corrosion inhibiting properties of lecithin by heating a lecithin oil composition for a period of time sufficient to produce darkening of the lecithin. An optional step further improves the corrosion inhibiting properties of the composition by combining zinc oxide with the lecithin oil prior to heating.
