http://www.viroshields.com - Protect yourself from environmental threats with VIROSHIELD HAND SANITIZER. This alcohol-based hand sanitizer spray meets FDA requirements and is made with 75% Isopropyl Alcohol Antiseptic, which can help reduce bacteria that can potentially cause disease. Washing your hands is always the best defense, but for times when you're out and about, hand sanitizer is your next best defense.
Hand sanitizer (also known as hand antiseptic, hand disinfectant, hand rub, or handrub) is a liquid, gel or foam generally used to kill the vast majority of viruses/bacteria/microorganisms on the hands.[3][4] In most settings, hand washing with soap and water is generally preferred.[5][6][7] Hand sanitizer is less effective at killing certain kinds of germs, such as norovirus and Clostridium difficile, and unlike hand washing, it cannot physically remove harmful chemicals.[5] People may incorrectly wipe off hand sanitizer before it has dried,[5] and some are less effective because their alcohol concentrations are too low.[5]

Hand rubbing.
Alcohol-based hand sanitizer that is at least 60% (v/v) alcohol in water (specifically, ethanol or isopropyl alcohol/isopropanol (rubbing alcohol)) is recommended by the United States Centers for Disease Control and Prevention (CDC), but only if soap and water are not available.[8] The CDC recommends the following steps when using an alcohol-based hand sanitizer:

Apply product to the palm of one hand.
Rub hands together.
Rub the product over all surfaces of hands and fingers until hands are dry.[8]
Do not go near flame or gas burner or any burning object during application of hand sanitizer.
