"The extract, known as oleoresin capsicum is made this way: hot chiles are furnace-dried, crushed, and pelletized. They are treated with hexane, which dissolves the capsaicin. The hexane is then evaporated, leaving an extremely hot, oily substance that can be further refined. Then it is used in pepper spray, topical analgesics, and extremely hot sauces" http://www.fiery-foods.com/ask-dave-...f/1214-AskDave
