What is the active ingredient in OC?

• A. Dihydrocapsaicin
• B. Capsicinoids
• C. Capsicum oleoresin
• D. Capsaicin

Answer: (D)

OC stands for oleoresin capsicum, a pepper spray formulation. The substance that actually causes the burning, irritation, and incapacitation is capsaicin. It binds to heat receptors (TRPV1) on mucous membranes and skin, producing the characteristic burning sensation, tearing, coughing, and incapacitation that OC is designed to produce.

Other terms describe related things but not the single active component. Dihydrocapsaicin is another capsaicinoid present in OC and can contribute to potency, but it is not the primary active ingredient. Capsicum oleoresin is the whole extract that carries capsaicin and other compounds, not the specific irritant itself. Capsaicin is the exact molecule responsible for the main effect, making it the best answer.
