Pepper spray is made up of an active ingredient called OC (Oleoresin Capsicum) and other inert ingredients. They can be water or oil based. The best formula being oil based as oil based products do not have the problem of separation.
The actual term OC (oleoresin capsicum) refers to chili peppers, and is a horticultural term. Jalapenos, chiletpin, cayenne, and habaneros are all chili peppers. Although they look quite different, and can taste quite different, they all contain an alkaloid called capsaicin. Capsaicin is tasteless and odorless. It is so powerful that even when it is immersed in water, the heat from it can be detected. Studies show that humans can detect even one part per ten million of this powerful alkaloid. To make Pepper spray, we must extract the oleoresin capsicum from the peppers, the OC is water soluble and oil soluble, we can use both to extract it. This is how itís done.
