What is Menthol?
Menthol is an organic compound with the chemical formula C₁₀H₂₀O. It is a waxy, crystalline substance, clear or white in color, which is solid at room temperature. While it can be extracted from natural sources like Mentha piperita (peppermint), most commercial menthol today is produced synthetically.
