Denatured alcohol is ethanol mixed with additives to make it unfit for consumption
To convert denatured alcohol into food-grade ethanol, the denaturants or additives must be removed through a process called "undenaturing." This process can vary depending on the specific denaturants used and the methods employed to denature the alcohol. In some cases, distillation techniques may be employed to separate the ethanol from the denaturants. However, it is important to note that not all denaturants can be removed through distillation, and more complex processes may be required.
One commonly used method for undenaturing denatured alcohol is azeotropic distillation. This process involves using solvents such as benzene or cyclohexane, which form azeotropes with ethanol and water. By distilling the denatured alcohol with these solvents, the ethanol can be separated from the denaturants and purified. However, it is crucial to select the appropriate solvent and carefully control the distillation conditions to ensure the effectiveness of the process.
Another approach to undenaturing denatured alcohol is extractive distillation. This technique utilizes a solvent that selectively extracts the denaturants from the ethanol. By distilling the denatured alcohol in the presence of this solvent, the denaturants can be removed, resulting in pure ethanol. Similar to azeotropic distillation, the choice of solvent and distillation conditions are critical for the success of extractive distillation.
It is important to note that undenaturing denatured alcohol requires specialized knowledge, equipment, and safety precautions. The processes mentioned above are simplified explanations, and the specific steps may vary depending on the initial denaturants and other factors. Attempting to undenature denatured alcohol without proper expertise and equipment can be dangerous and may result in an impure or unsafe product. Therefore, it is generally recommended to purchase food-grade ethanol from reputable suppliers instead of attempting to undenature denatured alcohol at home.

Food-grade ethanol is pure ethyl alcohol with no additives, safe for consumption
Food-grade ethanol is pure ethyl alcohol with no additives, making it safe for human consumption. It is also referred to as non-denatured or undenatured alcohol. To be labelled as food grade, ethanol must meet strict standards for purity and safety. It is produced in facilities that follow food-safe protocols and hygiene practices.
Food-grade ethanol is available as low as 190 proof (95% ABV) and as high as 200 proof (100% ABV). It is commonly used in tinctures, extracts, perfumes, and other applications where clean, non-toxic results are essential. It is also used in baking, cake decorating, and making candy. Food-grade ethanol is colourless and odourless and can be safely ingested. It is often used as a substitute for beverage alcohol, which may contain added flavours and higher concentrations of water.
Denatured alcohol, on the other hand, is ethanol that has been mixed with additives to make it undrinkable and safe only for external industrial uses. These additives, known as denaturants, can include isopropyl alcohol, methanol, bitrex (denatonium benzoate), tert-butyl alcohol, or other petroleum-based substances. The purpose of these additives is to make the alcohol taste bad, smell bad, or cause sickness, so people will not drink it. Denatured alcohol is also exempt from certain taxes because it is not meant for consumption.
It is important to note that while food-grade ethanol is safe for consumption, it is still a form of alcohol and should be consumed responsibly. Mixing ethanol with other liquids, such as fruit juice or lemonade, can be tricky, as ethanol and water do not easily mix. It is important to ensure that the mixture is properly combined to avoid consuming pure ethanol, which can be dangerous.
