Undenatured Ethanol: The Purest Choice for Industry and Lab Use
What is Undenatured Ethanol?
Undenatured Ethanol (CAS No. 64-17-5) is pure, food-grade or reagent-grade ethanol that has not been mixed with denaturants like methanol, Bitrex, or methyl ethyl ketone. Because it is free from impurities and additives, it is the gold standard for applications where chemical purity is non-negotiable.
Key Characteristics:
- Purity Levels: Typically 190-proof (95% ethanol) or 200-proof (99.9% anhydrous ethanol).
- Flammability: Highly flammable; requires strict handling and storage protocols.
- Solvency: Excellent solvent for organic compounds, essential for tinctures, extracts, and synthesis.
Applications: Why Use Absolute Ethanol?
Because it lacks the “poisonous” additives found in industrial-denatured alcohols, undenatured ethanol is the preferred choice for:
- Pharmaceutical Manufacturing: Used as a solvent for active pharmaceutical ingredients (APIs).
- Food & Beverage Production: Essential for flavor extracts (like vanilla) and as a processing aid.
- Botanical Extraction: The preferred solvent for creating high-purity essential oil extracts and herbal tinctures.
- Scientific Research: Used in histology, DNA extraction, and as a cleaning agent for precision lab equipment.
- Cosmetics & Personal Care: Found in premium colognes, perfumes, and sanitizers where skin safety is a priority.
Comparison: Undenatured vs. Denatured Ethanol
| Feature | Undenatured Ethanol | Denatured Ethanol |
|---|---|---|
| Purity | 100% pure (No additives) | Contains toxic denaturants |
| Consumption | Safe for human use (diluted) | Toxic/Not safe for consumption |
| Regulation | High taxation (excise duty) | Lower cost, tax-exempt in some regions |
| Best For | Food/Pharma/Lab | Industrial cleaning/Fuel |
Understanding Pricing and Market Trends
The price of Pure Ethyl Alcohol fluctuates based on global supply chains, agricultural harvests (for bio-ethanol), and regulatory excise taxes. On average, high-quality 200-proof undenatured ethanol prices range from $40 to $90 per gallon depending on volume, purity, and shipping logistics.
Large-scale industrial procurement via ChemicalsSuppliers.com often allows for significant cost savings through bulk pricing compared to small-batch laboratory retail stores.
Examples of Premium Ethanol Grades
- ACS Reagent Grade: The highest purity, meeting the standards of the American Chemical Society.
- USP Grade (United States Pharmacopeia): Meets the strict requirements for food, drug, and cosmetic use.
- Absolute Anhydrous Ethanol: Contains less than 0.5% water, ideal for moisture-sensitive chemical reactions.
Where to Buy Undenatured Ethanol

Frequently Asked Questions (FAQ)
Q: Can I use denatured alcohol for botanical extractions? A: It is strongly discouraged. Denatured alcohol contains additives that can contaminate your final product. Always use Food-Grade Undenatured Ethanol for anything meant to be consumed or applied to the skin.
Q: Does ChemicalsSuppliers.com provide documentation? A: Yes, every product on our website comes with a comprehensive SDS (Safety Data Sheet) and COA.
Q: Is there an excise tax on undenatured ethanol? A: Yes, because it is essentially high-proof spirit, it is subject to government excise regulations. Our team at ChemicalsSuppliers.com helps navigate the procurement process to ensure all compliance standards are met.
