Since I happen to have a copy of the MSDS for Kodak Photo-Flo 200 solution
nearby, here is the component information:
water [weight percent of solution: 60-70]
propylene glycol [weight % of sol'n.: 25-30]
p-Tertiary-octylphenoxy polyethyl alcohol [weight % of sol'n.: 5-10]
(also known under the trade name Triton X-100)
Hope this helps.
