Pepper spray

Pepper spray, oleoresin capsicum spray, OC spray, capsaicin spray, mace, or capsicum spray is a lachrymator (tear gas) product containing as its active ingredient the chemical compound capsaicin, which irritates the eyes with burning and pain sensations and so causes them to close, bringing temporary blindness. This blindness allows officers to more easily restrain subjects and permits people in danger to use pepper spray in self-defense for an opportunity to escape. It also causes temporary discomfort and burning of the lungs which causes shortness of breath. Pepper spray is used as a less lethal weapon in policing, riot control, crowd control, and self-defense, including defense against dogs and bears.

Pepper spray was engineered originally for defense against bears, cougars, wolves, and other dangerous predators, and is often referred to colloquially as bear spray.

The active ingredient in pepper spray is capsaicin, which is derived from the fruit of plants in the genus Capsicum, including chilis in the form of oleoresin capsicum (OC). Extraction of OC from peppers requires capsicum to be finely ground, from which capsaicin is then extracted using an organic solvent such as ethanol. The solvent is then evaporated, and the remaining waxlike resin is the oleoresin capsaicin.

An emulsifier such as propylene glycol is used to suspend OC in water, and the suspension is then pressurized to make an aerosol pepper spray. Other sprays may use an alcohol (such as isopropyl alcohol) base for a more penetrating product, but a risk of fire is present if they are used in combination with a taser.

Determining the strength of pepper sprays made by different manufacturers can be confusing and difficult. Statements a company makes about their product strength are not regulated.

There are several counterparts of pepper spray developed and legal to possess in some countries.

Pepper spray is an inflammatory agent. It inflames the mucous membranes in the eyes, nose, throat and lungs.

It causes immediate closing of the eyes, difficulty breathing, runny nose, and coughing. The duration of its effects depends on the strength of the spray; the average full effect lasts from 20 to 90 minutes, but eye irritation and redness can last for up to 24 hours.
