Which component in OC makes pepper sprays pungent?

• A. Propellant
• B. Carrier
• C. Capsaicinoids
• D. Nitrogen

Answer: (C)

Capsaicinoids are the compounds that give OC spray its pungent, burning effect. Oleoresin capsicum—the active irritant in pepper spray—contains capsaicinoids (including capsaicin and related compounds) that excite the sensory neurons in the eyes, nose, and throat, producing the characteristic heat, burning, tearing, and coughing. The other components are simply delivery aids: the propellant provides pressure to spray, the carrier bases the solution, and nitrogen is a gas used in some formulations. None of these cause the burning sensation; it comes from the capsaicinoids.
