I gargle with 10 mL ACT mouthwash, containing 0.02% fluoride, or about 2 mG fluoride which is 2,000 micrograms of fluoride. Three mG of your compound which is a hexafluoride, contains about
0.66 mG, or 660 micrograms of fluoride IF ALL THE FLUORIDE IS RELEASED. So, I wouldn't worry about the topical application of your compound, especially if it is neutralized and washed off quickly. Just use gloves next time.

Hi All:
One of our grad students was
dermally exposed to a few milligrams of solid (Benzotriazol-1-yloxy)tripyrrolidinophosphonium hexafluorophosphate, aka PyBOP [128625-52-5]. We read in the SDS that there is
some potential for the generation of HF due to the hexafluorophosphate anion, so calcium gluconate was applied twice and he was taken to
the ER.
It looks like the hydrolysis constant of PF6- is pretty low, but
we wanted to be on the safe side and recommended the ER visit.
What say you about this response?
