Hand sanitizers are nothing new and have been introduced for quite a long time. But its importance has only grown manifolds with the Covid-19 pandemic creating havoc the world over. It is considered to be a hand cleansing agent as the name derives and is also referred to as hand rub, hand rub, and hand antiseptic. It is available in gel, foam, and liquid form and is applied on the palms to eliminate common harmful pathogens that cause diseases. It is generally used if you travel to a place where you do not have instant access to clean water and quality soap. You can also use it if repeated hand washing tends to compromise your natural skin barrier. This means resulting in the formation of fissures or scaling in the skin. However, its effectiveness is stated to be variable. It is generally employed to control infection in diverse settings, ranging from healthcare centers, hospitals, clinics to cruise ships, supermarkets, etc. You can get hold of the best quality hand sanitizer in India like No Scars Hand Sanitizers.
Hand sanitizers are classified into two types depending on the users’ active ingredients, namely:
- Alcohol-free products: They are based on disinfectants like BAC (benzalkonium chloride) or antimicrobial agents like triclosan. Antimicrobial agent and disinfectant activities are persistent and instant. Most hand sanitizers are known to contain emollients like glycerin to soothe the skin, for fragrance as well as thickening agents.
- Alcohol-based products: They contain 60% to 95% alcohol, in form of n-propanol, isopropanol, or ethanol. Alcohol at such concentrations denatures proteins immediately, thereby neutralizing effectively certain microorganisms.
Effectiveness of hand sanitizers
Several factors tend to determine its overall effectiveness. It includes how the product is to be applied (like quantity used, the frequency used, duration of exposure, etc. It also takes into consideration if the person’s hands have some specific infectious agents, which may be susceptible to the product’s active ingredients. Alcohol-based sanitizers should be rubbed for about thirty seconds on hand surfaces and over fingers. Then it should be air-dried completely, thus reducing effectively the growth of fungi, bacteria, and a few enveloped viruses like Influenza A viruses. Certain alcohol-free formulations are reported to offer similar effects. Some are found to be relatively ineffective to combat non-enveloped viruses like norovirus, bacterial spores including encysted parasites like Giardia. Such hand sanitizers are reported to not sanitize or cleanse fully the skin, especially if the hands are soiled visibly before its application.
Although hand sanitizers vary in effectiveness, they can control infectious disease transmission. This is more so in those places where handwashing is not properly followed. For instance, in elementary schools, alcohol-free or alcohol-based sanitizers incorporated in the classroom are related to reducing absenteeism resulting from infectious diseases. Similarly, at the workplace, alcohol-based sanitizers are used and are related to reducing sick days and illness episodes. Healthcare clinics and hospitals are increasingly getting fast access to alcohol-based sanitizers, thus ensuring significant improvements noticed in hand hygiene.
