There was only one reference to antifoggants in the emulsion section IIRC. It was so insoluable in water that I have had trouble with it duplicating Agfa results. It recrystallizes in the emulsion when diluted from the alcohol solvent to the water based emulsion. Therefore, I doubt if it was the one. I don't have my data cards here right now to give the name, but it is so inexpensive, I tried it before I went on to the rarer ones that I used at EK.
