Well, it's a plausible theory. I normally used PF200 back then and never 
had any issues with that, perhaps due to lower concentration, but one time 
my supplier only had 5L of 600. I never actually used the stuff after it 
separated, there was no way I was letting it anywhere near film.

I kept it for several years as I couldn't think of a sensible way of 
disposing of it. I was quite tempted to tip the lot into the Trafalgar 
Square fountains on NY eve, in the hope of a few hundred cu.meters of 
bubbles, but it wasn't really foamy enough and I'd probably have got 
arrested anyhow.
