Chemical, if a strong solution it is like barbicide, otherwise diluted further it still has a weak smell. I have used it in the bath as I could not use it for food.
Well I went to a seminar on Savate, and thought it would be a fun film to watch. Having practiced some of these moves and seeing a real savate artist at work, what looks like fantasy on the film such as the way Charlemont reapears behind the back of one of the bad guys, can be done faster than the eye can catch. Awesome martial art and an interesting introduction.
