I don’t think you’ll find it. Mayonnaise has a mechanism of lipid oxidation catalysed by iron ions present in egg yolks. Most mass produced mayonnaise contains EDTA to chelate metal ions and slow down lipid peroxidation. Lipid oxidation is also known as rancidity.

You can test this yourself by leaving a metal utensil in some mayo for a couple hours. It should turn black from a redox reaction
