Acetone has no ingredients per se. Asking about the ingredients in acetone is like asking what the ingredients in water (H2O) are. If you take any atoms away from the molecule of acetone, it's no longer acetone. The chemical formula for acetone, however, is: (CH3)2 CO.

You'd more than likely die. Acetone should not be in the body in any circumstances.

Probably not the best thing to use for several resons. 1. Acetone is highly flammable. 2. Acetone will dissolve the glue holding the tile to floor. 3. It's fumes are noxious 4. It is easily absorbed into the body through the skin.
