Most pepper sprays (http://www.UBackOff.com) on the market today will take down a human nearly instantly. These sprays should also be somewhat effective against animals, ranging from bears to dogs, although they may have unpredictable effects. If your goal is to protect yourself from an animal attack, look for bear spray or dog spray, which is formulated for use against animals.
Canister Size and Capacity
This is one of the most important decisions you'll make regarding your pepper spray purchase, as it affects how you can carry the device. Pepper spray is available in a keychain or purse-sized canister, to a disguised pen-shaped device, to a larger canister designed to be kept near your front door. Even the tiniest canisters, typically containing a half-ounce of spray, contains enough pepper spray for twenty half-second bursts, certainly enough to take an attacker down. Those planning to carry pepper spray in their pocket or handbag to thwart muggers, carjackers, and other criminals should choose a small, convenient canister size.
Concentration and Chemicals
Most pepper sprays are based on OC (Oleoresin Capsicum), a chemical derived from hot peppers. Others contain chemicals abbreviated as CS or CN, although the most effective sprays contain OC. OC, a natural chemical, works instantaneously to cause temporary blindness and tears, uncontrollable coughing and lung inflammation, and a range of other symptoms. In addition to the chemical used, the strength of the pepper spray is also affected by its concentration, which typically ranges from about 6% to 18%.
Finally, the effectiveness of the spray is measured by its heat in Scoville Heat Units, or SHUs. This is the same scale used to measure hot peppers. Jalapenos come in at 5,000 SHU, and Habanero peppers up to 300,000. Pure OC is about 15 million SHU, although most commercially available pepper sprays range from 500,000 to 3 million SHU (http://www.UBackOff.com)
Pepper sprays can be released from the can in several manners, such as a fine mist, a fog, or a stream. A fog delivery method is ideal for spraying a large area, such as fighting a group of assailants. Meanwhile, streams deliver highly concentrated spray to a small area, and are recommended for those who are confident in their aim. Mists are easy to use for those who worry about the accuracy of their aim. In addition to the delivery method, the design of the canister also effects how far the spray will shoot, ranging from 4-8 feet for keychain canisters to 20 feet for a solid stream style pepper spray.
