Doing some research on GLDA vs EDTA and came across a discussion on the Chemistcorner site. According to one of their long time formulators and a professional chemist (MarkBroussard), GLDA is a more effective chleator than EDTA. Don't know if he bases that on testing he's done specifically or not, but thought it was pertinent to this conversation.

This one is very interesting. They are actually testing Trilon M, but have included GLDA and EDTA for comparisons. https://knowledge.ulprospector.com/media/2016/03/TrilonM_Webinar_Combined_04192016_v12-FINAL.pdf
So, is the GLDA/EDTA (whichever is used) added to the lye water, or the fats or after trace/cook depending on cp or hp?
Also, it seems GLDA is more effective if combined with CA. CA is added to the lye water and dissolved before adding lye, if GLDA is added with the lye water, is there a potential to cause an unpleasant chemical reaction when the lye is then added?
