FAQs

What is the denatured alcohol? ›

The term 'denatured alcohol' refers to alcohol products adulterated with toxic and/or bad tasting additives (e.g., methanol, benzene, pyridine, castor oil, gasoline, isopropyl alcohol, and acetone), making it unsuitable for human consumption. From: Encyclopedia of Food and Health, 2016.

While some online stores may market their products as “100% pure denatured isopropyl alcohol”, this is a misnomer. Pure isopropyl alcohol does not contain any denaturants.

Essentially, denatured alcohol is ethanol rendered unfit for human consumption by mixing in denaturants. A denaturant is a chemical ingredient that makes the ethanol unpalatable and gives it an unpleasant taste or smell.

Ethanol + Methanol​ is denatured alcohol. Denatured alcohol is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption.

Denatured alcohol can be used to disinfectant, sterilise medical equipment, as a window cleaner, and there are many more uses. Methylated spirits are also perfect for indoor or outdoor methylated heaters. It is an effective solvent in the paints, lacquers and varnish industry.

Use isopropyl alcohol in most of the same applications as denatured alcohol. It is safe for cleaning plastics, metals, anodized windshield repair injectors; as well as all other Delta Kits windshield repair equipment. Use DA with caution on printed products, logos or labels.

Answer and Explanation:

Isopropyl alcohol (rubbing alcohol) and denatured alcohol are not the same. They share some similarities, but have different chemical structures and have different uses. They are similar in that they can NOT be consumed by humans. They are both toxic if ingested.

The two types of alcohol have different chemical formulax : ethanol (C2H6O) and isopropanol (C3H8O). Isopropyl alcohol can be found as a bittering agent in denatured alcohol. After producers add bittering agents, denatured alcohol becomes more toxic than isopropyl alcohol.

Denatured alcohol and isopropyl alcohol have similar uses, but they differ chemically. Denatured alcohol is ethyl alcohol with toxic or bad tasting additives that make it unsuitable for consumption. The chemical formula of ethyl is C₂H₆O and the formula for isopropyl alcohol is C₃H₈O.

There is no chemical reaction between ethanol and water. However there is an interaction. Alcohol and water are both excellent solvents using hydrogen bonds to dissolve the solute. If you add water to alcohol, the mixture would be a solution of water in alcohol.

What states have banned denatured alcohol? ›

The State of California has joined a couple other states and Canada in banning Denatured Alcohol this year.

While acetone is not the same as denatured alcohol, they are used in some of the same processes. Both solvents can be used in the production of plastics, cleaning, degreasing, and as an additive for fuel. While there is overlap some, there are industries or uses exclusive to either acetone or denatured alcohol.

Denatured alcohol and isopropyl alcohol have similar uses, but they differ chemically. Denatured alcohol is ethyl alcohol with toxic or bad tasting additives that make it unsuitable for consumption. The chemical formula of ethyl is C₂H₆O and the formula for isopropyl alcohol is C₃H₈O.

Isopropyl alcohol shouldn't be used instead of denatured alcohol due to its lower concentration and water content (water may cause problems due to its slow evaporation rate). Its toxicity also means isopropyl alcohol can't be used in food preparation or food processing.

One of the most common uses of denatured alcohol is as a cleaning agent. Denatured alcohol can remove dirt, grease, glue, wax, and other types of grime from a variety of hard surfaces, such as wood, glass, and plastic. Denatured alcohol can be utilized to fuel small camping stoves and oil heaters.
