Foam Hand Sanitizer Composition
A foam hand sanitizer works by forming up a lather. Foam sanitizers have an active ingredient that is quaternary ammonium, Benzalkonium Chloride. Contrary to alcohol-based products, non-alcohol foam sanitizers generally have lower than 0.1% concentration of Benzalkonium. Yet they provide almost the same level of protection. Mainly water is the remaining content. It is also enhanced with skin moisturizers such as vitamin E and aloe extract. These are relatively non-toxic due to low concentrations of Benzalkonium and it is non-inflammable too.
Some instant foam hand sanitizers contain antiseptic and bio-certified ethanol, which is considered as an alternative to ethyl alcohol. Instant foam hand sanitizers remove germs without water.
Foam Hand Sanitizers vs Alcohol-Based Sanitizers
Let's discuss the benefits of foam hand sanitizers over alcohol-based gel sanitizers

Foam sanitizers have an easy application that creates bubbles that roll out on the skin rendering easy cleansing. Whereas, gel sanitizers simply create a coating over the hand, which requires a more intense effort to spread it all over the hands.
Foam hand sanitizers have a non-sticky feel on hands after application. Many conventional alcohol sanitizer gels contain polymer for thickening in them and other ingredients that can feel sticky after application
The Alcohol-based products to eliminate bacteria until the skin gets dried. Whereas, even after the solution has dried, benzalkonium based foam hand sanitizers provide protection for some period.
The revitalizing and bursting action of bubbles in foam hand sanitizer help to remove dirt and dead skin cells and effectively inhibit germs and bacteria. Whereas, the alcohol-based gel has a static state that provides germ protection but merely traps dirt and dead skin cells.
