Hi all,
Discussion in another thread concerning DOS prompted my interest in additives that reduce the risk of fatty acid oxidation and rancidity in soap.

This paper mentions different combinations including ROE +EDTA and BHT + Sodium...
When it comes to using chelating agents, what are your preferences? I know some use EDTA others Sodium Citrate. Are there others you prefer to use? Also, why do you prefer one over the other?
I have been using Citric Acid and Sodium Hydroxide to make my own Sodium Citrate.
