text: what are the ingredients in "pepper spray"?   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.
