I wish they would go back to adding this to ethanol to make denatured alcohol for use as cooking fuel and solvent. Nowadays, when you buy denatured alcohol you're likely getting a witches brew of ethanol, methanol, MEK, MIBK, and acetone with an exact formula that is nearly impossible to pin down and changes all the time. Not optimal if you want something relatively non-toxic and want to know in advance exactly what it will and will not dissolve.
