Wildfire is 18% Oleo Resin Capsicum (pepper) — a derivative of 3 Million Scoville Heat Units (SHU). The WildFire 9oz Pepper Spray 18% Fire Master contains 38 one second bursts with a range of 20 feet.
The Wildfire 18% formula is one of the hottest, and more importantly, the fastest reacting spray we’ve ever tested. This spray immediately permeates the pores of the skin, closes the eyes, and inhibits the respiratory system. What makes this product so effective is the purity of the pepper used in formulating this product…only food grade grade 3 million or 4 million scoville heat units pepper used. – Larry Harris, Washington Labs
