text: Our Pepper Spray products contain the ingredient called Olesoresin Capsicum (OC).  They come in either 10% or 15% (the highest percentage allowed by law), and have a 2 million Scoville heat rating.  OC is a derivative of hot cayenne peppers.  It is pure, non-toxic and nonflammable.  OC is not an irritant like tear gas but an inflammatory agent.
