It is quite common to us to wash our hands using Hand soap on a daily basis. But how many times have you actually pondered over the mechanisms associated with Hand soaps and their functions in getting rid of germs? It may appear as though it is some form of magic, however, there is science involved! Whether it’s dirt, bacteria, or viruses, hand soap plays an indispensable role in ensuring one’s good health. So let’s break it down in the most human-friendly way.
The Science Behind Hand Soap
Hand Soap is a detergent and also a cleaning agent which can help remove dirt and oil from our skin. But when it comes to germs, Hand soap does something even more powerful – the Hand soap ruptures the germ and removes it.
Analysing the above statement, few important points can be drawn.Hand Soap molecules contain two parts: one that is attracted to water (hydrophilic) and one that is attracted to oil and grease (hydrophobic).
When you rub Hand soap on your hands, the hydrophobic side grabs on oils, dirt, and germs. The other side loving water then reacts with water, which permits the Hand soap to remove and wash away all the grime when you rinse.
This is pretty straightforward -Hand soap collects dirt and germs and with the use of water, it washes them away: simple, isn’t it?
How Soap Kills Germs and Viruses
Bacteria and viruses usually possess a protective fatty external layer.Hand Soap works wonders because it separates the fat, effectively removing the germ’s protective cover. After that protective layer is removed, the virus or bacteria disintegrates and becomes harmless.
This is why washing with Hand soap is way more useful than simply rinsing, – because water cannot break down those fatty membranes!
Why 20 Seconds of Handwashing Matters
If I had a nickel for each person that’s heard about the 20 second minimum hand washing rule, I would be broke. But, do you know why there is a time limit?
The more you scrub, the more friction you create, which contributes to dislodging as many germs as possible from your skin.
Hand Soap needs some time to effectively breakdown oils and bacteria.
If you rush the process, it’s likely that you will leave some strong germs behind – most likely under your nails or between your fingers.
A solid piece of advice? Sing the “Happy Birthday” song twice while washing your hands and you are good to go!
Does Antibacterial Hand Soap Work Better?
You may be tempted to think that antibacterial Hand soap is essential to have, but in most cases, a regular hand wash Hand soap will work just fine. It is the mechanical scrubbing and rinsing action that is effective in removing the germs.
While antibiotic Hand soaps do try to get rid of bacteria with added ingredients, this particular Hand soap does not work better than ordinary Hand soap when it comes to viruses (the flu or COVID-19). Not to mention, overutilization of these products can lead to resistance to antibiotics, thus for everyday patients it is best to use regular Hand soap!
Final Thoughts
Though Hand soap may appear to serve the primary purpose of cleansing, when it comes to your hands, it is a true lifesaver.Hand Soap works by destroying bacteria and preventing infections as well as allowing your skin to remain clean all while protecting those nearby.
Therefore, when you plan on washing your hands next time, remember: 20 seconds, lots of foam, and rinse thoroughly – as Hand soap is the first step in the fight against germs!
