How To Make Pepper Spray & Teargas

Pepper spray (also known as teargas, or OC spray (from “Oleoresin Capsicum”), OC gas, capsicum spray, or oleoresin capsicum) is a chemical compound that irritates the eyes to cause tears, pain, and even temporary blindness that is used in riot control, crowd control, and personal self-defense, including defense against dogs and bears.

The active ingredient in pepper spray is capsaicin, which is a chemical derived from the fruit of plants in the Capsicum genus, including chilis. Extraction of oleoresin capsicum from peppers involves finely ground capsicum, then the capsaicin is extracted in an organic solvent such as ethanol. The solvent is then evaporated, and the remaining waxlike resin is the oleoresin capsicum. An emulsifier such as propylene glycol is used to suspend the OC in water, and pressurized to make it aerosol in pepper spray.

The high performance liquid chromatography (HPLC) method is used to measure the amountof capsaicin within pepper sprays. Scoville Heat Units (SHU) are used to measure the hotness of pepper spray.

Included in this category are multiple methods for the preparation of teargas and pepper sprays. Included are methods for producing improvised homemade pepper spray.
