0.05% of the total solution (weight for volume) or 0.5% of the
susceptible organic material (gelatin, gum, sugar, etc.; weight for
weight), whichever is higher. This agent is very effective and the
dose is not very critical.

Alternatively, if you are already using thymol, use about 1/4 of the
quantity you find effective for thymol.

I haven't figured out suitable solvent for stable stock solution. You
can buy sodium salt of 2-phenylphenol, which is a lot easier to
dissolve in water. I think sodium salt is more common in bactericide
market. (Bayer and Dow make them.)
