Denatured alcohol (aka methylated spirit) is ethanol that has additives such as methanol to make it toxic so as to discourage recreational consumption and exempt it from liquor excise taxation. It’s a popular alcohol stove fuel because it’s affordable, relatively clean-burning, and more widely available than ethanol.
How toxic is denatured alcohol?
In small amounts, denatured alcohol is usually no problem in cosmetics unless it’s mixed with methanol, which can seep in through the skin. However, while denatured alcohol isn’t toxic at the levels needed for cosmetics, it can cause excessive dryness and disturb the natural barrier on your skin.
What is the difference between alcohol and denatured alcohol?

The only downside of 99% isopropyl alcohol is that, understandably, it needs to be used and stored properly. In this concentration, it is highly flammable, may cause dizziness if used in high quantities in an ill-ventilated area, and can be an irritant to skin and eyes. Of course, it should also never be ingested.
