The active ingredient in Photo-Flo is Triton X-100. The following formula is similar to Photo-Flo.

Distilled water 600 ml
Propylene glycol 250 ml
Triton X-100 75 ml
Water to make 1 l

This formula omits the antifoaming agent in Photo-Flo which can leave greasy spots on the film. It is also hard to obtain in small quantities.
