Using old-school lye will get rid of PFAS on your clothes. I wonder if that was considered during these tests.

Last time I played around with DMSO I made an ibuprofen ointment similar to the diclofenac ointments there were expensive and prescription-required back then.
I'd apply some to my skin and it would absorb very quick and I'd get digestive upset even more quickly than if I took ibuprofen pills so it was a success and a failure at the same time.
IIRC we explicitly didn't use DMSO because of concerns with toxicity, and just accepted that the absorbance rate was astonishingly low, clinical trials suggested that it took 24-48 hours for the active ingredient to be detected in the blood.
My recollections are hazy, this was over 30 years ago
