200 Proof Ethanol
Pristine Alcohol is bringing its ultrapure production standard to 200 proof. The same 100% stainless steel equipment and 100% Michigan-grown corn behind our 190 proof line — now dehydrated to less than 0.5% water for applications where even trace water is unacceptable. Five formulations are launching soon, including 200 proof versions of formulas we already produce at 190 proof.
What Is 200 Proof Ethanol?
200 proof ethanol — is ethyl alcohol with virtually all water removed, containing less than 0.5% water. Conventional distillation tops out near 190 proof because ethanol and water form an azeotrope; reaching 200 proof requires an additional dehydration step beyond distillation. The result is a solvent with under 0.5% water essential for chemical synthesis, laboratory work, fuel applications, and formulations where water causes haze, side reactions, or spoiled finishes.
200 Proof Formulations
200 Proof SDA 40-B
The same trusted 40-B formula behind our 190 proof line — tert-butyl alcohol and Bitrex denaturants in a base containing less than 0.5% water. Ideal for perfumes, personal care, and water-sensitive formulations.
200 Proof SDA 3-A
Methanol-denatured 200 proof ethanol built for chemical synthesis, coatings, and industrial processing where water content ruins reactions and finishes.
200 Proof SDA 3-C
Isopropyl-alcohol-denatured 200 proof ethanol — a versatile, lower-toxicity industrial solvent for cleaning products, coatings, and chemical intermediates.
Reagent Alcohol 200 Proof
The lab-standard 90/5/5 ethanol-methanol-isopropanol blend on a 200 proof basis with less than 0.5% water. Histology, chromatography, molecular biology, and general laboratory use.
200 Proof CDA 12-A
Completely denatured alcohol per 27 CFR 21.26 — no TTB permit required to purchase. Fuel, industrial cleaning, and manufacturing applications.
190 Proof vs. 200 Proof — Which Do You Need?
Several of these formulas mirror products we already make at 190 proof, including SDA 40B. The difference is water: 190 proof ethanol is roughly 95% ethanol and 5% water, while 200 proof contains less than 0.5% water. If your process tolerates a small amount of water, 190 proof is usually the more economical choice. Choose 200 proof when your application is moisture-sensitive — chemical synthesis, low-water formulations, laboratory protocols, fuel blending, or any specification that calls for absolute ethanol.
Frequently Asked Questions
How much water is in 200 proof ethanol?
Pristine 200 proof ethanol contains less than 0.5% water, compared to 190 proof ethanol which contains about 5% water.
Why does 200 proof ethanol cost more than 190 proof?
Ethanol and water form an azeotrope at about 95.6% ethanol by volume, so standard distillation cannot exceed roughly 190 proof. Producing 200 proof requires an additional energy-intensive dehydration step, which adds production cost.
Do I need a TTB permit to buy 200 proof denatured ethanol?
It depends on the formulation. Specially denatured alcohols (SDA 40-B, SDA 3-A, SDA 3-C) require a TTB industrial alcohol user permit. Completely denatured alcohol (CDA 12-A) requires no permit. Reagent alcohol typically ships to laboratories without a user permit. Our team assists with all TTB documentation.
