Acetone is a clear, colorless liquid that is highly flammable. The potential negative health effects are skin, eye and lung irritation. Long-term exposure can result in dry, cracked skin and possible damage to the nervous system. Here is a sample MSDS for acetone in the GHS format (not for official use).
It's weak because it's been stepped on too hard. No amount of resynthesis is going to make it any better. But you can quickly and easily purify what you do have... Go to a hardware store and get a can of acetone. Acetone is flammable, so be careful not to use it around sparks or open flame. Aside from the very small risk of fire, acetone is pretty benign stuff as far as solvents go. Go to the drug store and get some Epsom salts (MgSO4).
