Capsaicin and related capsaicinoids are the Active Ingredients within Oleoresin Capsicum. Commonly referred to as OC, it is a natural, oily, resin-like substance derived from hot peppers, the same ones used in spicy foods. Bear sprays that contain OC induce an almost immediate but temporary burning sensation of the skin and a burning, tearing, and swelling of the eyes. If OC is inhaled, the respiratory tract becomes inflamed resulting in swelling of the mucous membranes lining the breathing passage and temporarily restricting breathing to short, shallow breaths.
Counter Assault developed the sophisticated dispersal system that creates an atomized fog, which produces a pepper cloud slow to dissipate. The most effective dispersal system is the atomized fogger.
To be effective, Counter Assault Bear Deterrent must be airborne. Do not spray this product on objects, tents, or humans; such use has NO deterrent effect on bears.
