Publisher's Synopsis
Hand sanitizer is a liquid, gel, or foam generally used to kill the vast majority of viruses/bacteria/microorganisms on the hands. In most settings, handwashing with soap and water is generally preferred. 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. People may incorrectly wipe off hand sanitizer before it has dried, [5] and some are less effective because their alcohol concentrations are too low. This book will give you steps to make homemade hand sanitizer and guide how to make these disinfectants.
