Denatured Alcohol vs Non-Denatured Ethanol - What's different and what's the same?

About denatured alcohol vs nondenatured ethanol - Culinary Solvent

Not all alcohols are created equal.  Ethanol is an alcohol, but not all alcohols are ethanol. Only pure ethanol, containing no additives, is considered safe for body and skin. Use this page to understand the differences between "denatured alcohol" and "non-denatured alcohol", including what makes Culinary Solvent the best substitute for applications calling for denatured alcohol.

What is denatured alcohol?

Denatured alcohol, or also Specially Denatured Alcohol SDA, is ethyl alcohol plus some toxic additive chemical.  This chemical, the denaturant, may be any number of the approved additives by the federal government based on the additive's toxicity to humans.  The primary purpose of adding a denaturant is to inhibit consumption for the purpose of intoxication.  Denatured alcohols are not denatured for enhanced performance or longevity, and are inherently toxic by their nature.  Because of this additive, denatured alcohol is exempt from the Federal Excise Taxes imposed on pure non-denatured ethanol. 

What is nondenatured ethanol?

Nondenatured means no additives. Nondenatured ethanol is pure ethyl alcohol, which also goes by the name "ethanol".  Only nondenatured ethanol is "food safe" and "safe for consumption".  Nondenatured ethanol is the same alcohol found in beverage products below 100 proof, or in non-beverage products available in 190 proof (95%ABV) and 200 proof (100%ABV Anhydrous Alcohol).

Can nondenatured ethanol be substituted for denatured alcohol?

Yes. Nondenatured ethanol can be substituted for recipes calling for denatured alcohol.  Be sure to choose a nondenatured ethanol with zero water (200 proof) or as high as 5% water (190 proof) for optimal results.  Ethanol with a higher water content than 5% may not provide the same results, or can affect your project in other ways (crafters applying a French polish for example benefit from 0% water). 

Can denatured alcohol be substituted for nondenatured ethanol?

No.  This is important to stress that the toxic additives that make an alcohol denatured mean it is not possible to substitute denatured ethanol for recipes that call for "nondenatured ethanol".  Not all alcohols are created equal, liquids labeled as "denatured alcohol" are guaranteed to contains toxic additives and should be avoided if there is chance of human exposure.

Learn More About Non-Denatured Ethanol

When shopping for denatured alcohol or nondenatured ethanol, knowing the key industry terms will help you buy smart. Get familiar with the following important terms:

“Non-denatured” means “No Additives”
  • Only nondenatured ethanol is PURE ethanol.
  • "Undenatured ethanol" is synonymous with Nondenatured.
  • Nondenatured ethanol is food safe, and safe for human consumption as a tincture, extract, or concentrate.
“Denatured” means “Toxic Additives” + Ethanol
  • Additives eligible as denaturants are approved based on their human toxicity
  • All denatured ethanol is poisonous and unfit for human consumption.
  • Licenses, permits, fees and some taxes still apply to denatured alcohol in many instances.
Dehydrating the last 5% water
  • Water and ethanol in solution at 95.63% ABV (191.26 proof) form an azeotrope or “constant boiling point mixture”.  This means normal distillation alone cannot remove the last 4.37% of water.  Another process must be applied to eliminate the water.
  • Some manufacturers dehydrate the remaining water with harmful chemicals like methanol or benzene.  These chemicals are also toxic to humans and alcohol products dehydrated with methanol or benzene are not considered food safe.
  • The safest way to dehydrate ethanol uses a device called a "molecular sieve".  Engineered from ceramic, molecular sieves literally trap the water molecule from the alcohol solution, resulting in a dehydrated 100% ethanol leaving the system.

3 Questions to Always Ask About Your Alcohol:
