What are the different types of foam hand sanitizer?

As society's understanding of germs and how they spread improves, the importance of handwashing has become clear. The search for the most effective and convenient way to get rid of germs on your hands has turned from ordinary soaps and water washes to hand sanitizing formulas that often don't require water to wash or towels to dry. A popular form of this type of sanitizer is foam hand sanitizer, which comes in alcohol-based, benzalkonium chloride-based, and scented and moisturizing forms. When combined with motion-sensing dispensers that don't require manual pumping, foam hand sanitizers can be very effective at killing and reducing the spread of germs in public places and at home.

A common form of foam hand sanitizer is the alcohol-free benzalkonium chloride formulation, which has been used in hospitals and schools since the mid-20th century. An important benefit of the alcohol-free antimicrobial solution is that it is non-flammable and non-aerosol, making it a safer and more environmentally friendly product. Benzalkonium Chloroid Foaming Hand Sanitizer can actually provide up to three hours of germ protection on your hands with a single use, so the more you use it, the more effective it becomes at killing germs.

Alcohol-based sanitizers are more often found in gel forms compared to foam forms, but foam dispensers make it possible for gels and liquids to produce a foam foam. An alcohol-based foam hand sanitizer contains at least 60 percent alcohol and is effective at killing 99.99 percent of germs on hands. After the sanitizer dries on hands, usually within eight to 10 seconds, there is no residual protection to kill germs, and it must be reapplied frequently. Studies have shown that frequent use of alcohol-based sanitizers can strip skin of protective cells and oils, making hands more vulnerable to germs.

Scented and moisturizing formulas are also available due to concerns regarding dry hands and strong chemical odors. These sanitizers are more commonly available in personal or home bathroom hand sanitizer dispensers than in commercial dispensers found in hospitals, schools, and places of business. An added benefit of scented foam hand sanitizers is that the more pleasant the scent is to the consumer, the more likely and more often they will use it. Although benzalkonium chloride sanitizers do not have the drying effects of alcohol-based sanitizers, moisturizing ingredients and essential oils have been added to certain brands to appeal to skincare-conscious consumers.
