Hand sanitizer is an instant type of cleansing material that can be safely used by children and adults in almost any setting. It is very simple to use and requires a minimal amount of effort. Without using water or a towel, a pea-sized amount of hand sanitizer can be spread between the hands and fingers and then rubbed together until dry. Hand sanitizer helps to prevent the spread of germs and to keep hands clean and fresh.
Types
Hand sanitizers come in three main types: gel, liquid wipes and foam. Gel hand sanitizer is most commonly used as a travel accompaniment because it can easily fit into purses or pockets and be carried everywhere. Liquid wipes are another alternative for those who prefer to wipe down surfaces they use, such as shopping cart handles, doorknobs and furniture. Foam versions are economical and used in large, populated or public areas such as hospitals, doctors' offices and schools. Many health care facilities promote using the sanitizer to help prevent the spread of germs.
Ingredients
Most hand sanitizers are made from active ingredients, including ethanol and isopropanol. Inactive ingredients may include glycerin, polyacrylic acid, propylene glycol and essential oils for scent. There are some brands that are alcohol-free and use benzalkonium chloride or triclosan to help kill germs.
Killing Germs
According to Purell.com, everyone needs some germs on their hands. These are called resident germs and help keep humans healthy and thwart some illnesses. Transient germs are germs that can be passed on from others and can make people sick. Hand sanitizers help kill transient germs while preventing bacterial resistance in most situations. Most hand sanitizers are designed to kill up to 99.99 percent of germs, making them, in some cases, more effective than hand washing.
Avoiding Illness
Hand sanitizers may help people avoid many types of illness. Some examples include tuberculosis, some strains of influenza and the common cold. Because most hand sanitizers also combat fungi and bacteria, they can also be used after handling meat or food-borne contaminated surfaces.
Substitute for Handwashing
If you have come into contact with a contaminated surface, the hand sanitizer may help to kill off the bacteria or virus before it enters the body. In many cases hand sanitizer can be a temporary substitute for hand washing until you are able to access soap and water. Because contaminants are not being washed away, refrain from touching others or placing things in your mouth by hand until the hand sanitizer has completely dried.
