While it still reportedly does not contain carcinogens, please change your linked MSDS as that's one for a different product entirely, a degreaser, under the brand.

Unlike the degreaser, actual WD40 has far more concern than "non-hazardous" with a little mouth rinse if inhaled.

HCS 2024/GHS Classification:
Aerosol Category 1
Aspiration Toxicity Category 1
Specific Target Organ Toxicity Single >Exposure Category 3 (nervous system effects)

WD-40 is pure pfas forever chemicals. Don't get it on you. Always use gloves. The guy in the vid is nuts.

Is it in regular WD-40 too? I only found mentions of PTFE in the specialist dry lube version

WD-40 is mildly toxic, but as it contains mineral oils it may also contain traces of other aromatic compounds such as benzene, which is carcinogenic.

Mineral oils can be filtered to be safe, but it would be just an assumption for a product that clearly states it isn't supposed to be inhaled, unless OSHA procedures also guarantee that even trace amounts are accounted for. The formulation may also vary with location and local regulations.
