Hand sanitizer dispensers kill bacteria through the active ingredient of alcohol. Alcohol makes up anywhere from 60 to 90 percent of the sanitizer, and anything less than 60 percent may not be effective in killing bacteria. The secret is when the active ingredient of alcohol is put onto a potentially bacteria filled area, it damages the particles. It will only work if the sanitizer is put into direct contact with the area infected.
Hand sanitizer does work on the hands but does prevent bacteria that may be encountered on surfaces later. It will kill bacteria on contact, but is not effective after that. This translates that hand sanitizer must be constantly used, but the high alcohol content can dry out skin and even irritate it.I strongly suggest you to look at this site
Soap is very different than using a sanitizer. When an individual washes their hands with soap, bacteria particles are removed from the skin entirely. In contrast, sanitizers just neutralize the particles, they are not removed. So those particles stay on the skin but no longer can cause any harm. The best process is to use both, using the sanitizer after washing hands. Sanitizer should be rubbed into the hands for approximately thirty seconds, and it really neutralizes a variety of bacteria. It has been shown to even protect from MRSA, a flesh eating bacteria that can be deadly.
To even further the already many benefits of hand sanitizer, people that use it also show slower redevelopment of bacteria. Everyone has some form of bacteria on their hands at any given time. It does not prevent all germs, as some are airborne, but it is still a great product.
Although hand sanitizer is a wonderful product, it should not be used for everything. If hands are exposed to blood for example, they should be washed with soap and water. In addition, it is not good in the food service industry because hands get wet a lot from food preparation, and does not properly remove fecal mater on the hands from improper hand washing after restroom use.
When purchasing hand sanitizer, check the alcohol content in it. The higher the concentration of alcohol, the more effective it will be. There are even a variety of scents available as well, and there are even miniature dispensers that can be put into a purse or a travel bag for use as well. They should be used all year, but are even better to protect us during the winter months with many viruses going around.
