>>7819539This is literally rebottled acetone with a markup. No additives, it's literally straight acetone.
It's the same as nail polish remover and people get it all over themselves all the time.
Problems arise when you vaporise it and then breath the aerosol directly. If your mask can filter regular paints and solvents (lacquer, acrylic, alcohols, turpenoids etc) then it can filter acetone. If your mask can't, then you shouldn't be spraying anything at all.
