Using WD-40 in residential applications often results in inhalation of aerosolized particles and injestion/absorption of residue on skin.

How can a consumer make an informed decision about using WD-40 without knowing what it's composed of?

I just search online for the MSDS for the product.

Just use common sense, assume all aerosols are toxic, then temper your concerns by remembering the frequency of your exposure to that toxin, and compare it mentally to how much garbage we inhale walking around the average city.
