Pure capsaicin measures 16 million Scoville Heat Units (SHU), the highest possible value on the Scoville Scale. This concentrated chemical compound is not safe for human consumption and is primarily used in industrial applications such as bear spray and medical research. According to the U.S. Food and Drug Administration (FDA) and scientific literature, pure capsaicin is the most potent form of the heat-producing compound found in chili peppers.

What Is the Scoville Scale?
The Scoville Scale, developed by Wilbur Scoville in 1912, measures the pungency (spiciness) of chili peppers and other spicy foods in Scoville Heat Units (SHU). Modern methods use high-performance liquid chromatography (HPLC) for objective measurement, but SHU values remain the standard reference. According to the National Institutes of Health (NIH), this scale quantifies how much sugar water is needed to dilute capsaicin until heat is undetectable.
How the Scoville Scale Works
- Lower End: Bell peppers at 0 SHU — no capsaicin.
- Mild Range: Jalapeños at 2,500–8,000 SHU — safe for everyday cooking.
- Hot Zone: Habaneros at 100,000–350,000 SHU — requires caution.
- Extreme Territory: Carolina Reapers at 1.5+ million SHU — can cause severe discomfort.
- Pure Fire: Pure capsaicin at 16 million SHU — the highest possible value.
Pure Capsaicin and Its Power
Pure capsaicin (C₁₈H₂₇NO₃) is the isolated chemical compound responsible for chili pepper heat. As documented by PubChem (a database from the NIH), it binds to TRPV1 receptors in sensory neurons, triggering heat and pain responses. This makes it unsuitable for direct consumption.
Property | Description |
---|---|
Chemical Formula | C₁₈H₂₇NO₃ |
Molecular Weight | 305.41 g/mol |
Solubility | Insoluble in water, soluble in fats and alcohol |
Natural Source | Chili pepper placenta (white inner membrane) |
SHU Value | 16,000,000 |
According to the FDA, capsaicin has therapeutic uses in pain management creams but requires professional handling due to its potency.
How It Compares to Other Spices
Pure capsaicin is dramatically hotter than edible peppers. The following comparison shows the Scoville Scale differences:
Spice | SHU Range | Typical Use Case |
---|---|---|
Bell Pepper | 0 | Kid-friendly meals, stir-fry |
Jalapeño | 2,500–8,000 | Salsas, nachos |
Habanero | 100,000–350,000 | Hot sauces, Caribbean dishes |
Ghost Pepper | ~1,000,000 | Extreme hot sauces |
Carolina Reaper | ~1.5–2.2 million | World record challenges |
Pure Capsaicin | 16,000,000 | Laboratory research, bear spray |
As confirmed by Guinness World Records and scientific studies, pure capsaicin is over 7 times hotter than the Carolina Reaper and 46 times hotter than a habanero.
Practical Tips for Handling Extreme Heat
Per OSHA guidelines and FDA safety protocols, pure capsaicin requires professional handling. These tips apply to extreme heat sources:
- Wear gloves: Essential for anything above 10,000 SHU to prevent skin irritation.
- Avoid touching face: Capsaicin can cause severe eye damage — never rub eyes after handling.
- Use ventilation: Work near a fan or range hood to avoid respiratory irritation.
- Use dairy to cool down: Milk or yogurt neutralizes capsaicin; water is ineffective.
- Label everything clearly: Prevent accidental exposure with clear markings.
First Aid for Overexposure
Per FDA emergency guidelines:
- Rinse eyes with milk or saline solution for 15+ minutes.
- Apply vegetable oil or aloe vera to skin contact areas.
- Drink milk or eat bread for ingestion; seek medical help if symptoms persist.
- Call emergency services for breathing difficulties.

Frequently Asked Questions About Pure Capsaicin and the Scoville Scale
Answers based on FDA, NIH, and PubChem sources:
- What is the Scoville value of pure capsaicin?
Pure capsaicin measures 16 million Scoville Heat Units (SHU), the highest possible value on the scale. This is confirmed by the U.S. Food and Drug Administration and scientific literature. - Can you eat pure capsaicin?
No. At 16 million SHU, it is approximately 16,000 times hotter than a jalapeño and would cause severe chemical burns. The FDA explicitly prohibits direct consumption. - Why is pure capsaicin so high on the Scoville Scale?
The Scoville Scale measures capsaicin concentration. Pure capsaicin is 100% concentrated compound with no dilution, making it the theoretical maximum. PubChem data confirms this value. - Is pure capsaicin used in food?
No. Pure capsaicin is not used in food preparation. Only heavily diluted extracts (below 10,000 SHU) are permitted in commercial hot sauces under FDA regulations. - How does pure capsaicin compare to the hottest peppers?
Pure capsaicin (16 million SHU) is 7 times hotter than the Carolina Reaper (2.2 million SHU) and 46 times hotter than a habanero (350,000 SHU), according to Guinness World Records and NIH studies. - Where can I buy pure capsaicin?
Pure capsaicin is not available for consumer purchase. It is regulated by the FDA and sold only to laboratories, law enforcement (for pepper spray), and wildlife management. Consumer products must use diluted extracts. - What are the dangers of pure capsaicin?
Per OSHA guidelines, pure capsaicin causes severe chemical burns, permanent eye damage, and respiratory distress. Ingestion can lead to gastrointestinal damage and cardiovascular issues. It requires professional handling equipment.
Conclusion
The Scoville Scale provides critical insights into capsaicin's properties, but pure capsaicin's extreme potency requires strict safety protocols. According to the FDA and NIH, this compound is strictly for industrial and medical use — never for consumption. Always rely on authoritative sources like the U.S. Food and Drug Administration for accurate information about spicy substances.
