Capsaicinoids are the active compounds found in oleoresin capsicum, which is the primary component of OC (oleoresin capsicum) agents, commonly used in pepper sprays and other self-defense products. These compounds are the source of the burning sensation and irritation that users and subjects experience when exposed to OC agents. Capsaicinoids work by activating sensory neurons, specifically those that convey pain, thus causing intense irritation to the eyes, skin, and respiratory tract.

The other options do not contribute to the irritation caused by OC agents. Industrial solvents are chemicals used in manufacturing and do not have the same irritative effects associated with OC agents. Hydraulic agents refer to fluids used in hydraulic systems and are unrelated to chemical irritants. Vaso-dilators are substances that cause blood vessels to widen, which is not related to the mechanisms through which OC agents cause discomfort and irritation. Therefore, the correct answer is Capsaicinoids, as they directly correlate to the effects experienced with OC agents.
