What Puts The "Hot" in Pepper Spray?

I'm assuming everyone know that there's really pepper in pepper spray, but how do they get it in that little canister?

Somehow, in the pepper spray factory, the hot capsicum extract is sucked out of those hot little peppers, mixed with a solution of liquids like water and propylene glycol (an emulsifier-makes it mix up good). Then it's all pressurized in an aerosol canister so you can spray it at the bad guys.

Because of the mixture, someone can't just wash the stuff off his face after being sprayed. Splashing only water will help, and time, about 30-45 minutes. Soaps and creams will just work it into the skin.

The different amounts of "hot" in pepper sprays depends on the peppers used and how concentrated the solution is. So make sure you buy the strongest pepper spray available to stop any attackers.
