Photoflo 600 is the 'industrial' version. It has 3x the concentration of Triton and uses ethylene glycol rather than propylene. It will suds-up just like PF200.
If there were to be an anti-foaming agent I'd lay odds it would be good ole' Dimethylpolysiloxane.
I add PF directly to a bottle of isopropyl alcohol. 13ml of PF600 to a quart of 70% isopropyl gives a stock that gets diluted 1:7 for use (1oz per 35mm film reel).
