    The document discusses how soap works to remove pathogens from hands. It explains that soap molecules have two ends - a hydrophilic end that attracts water and a hydrophobic end that repels water. This allows the soap to bond with oils, pathogens and debris on hands. When washing, the soap attaches more strongly to germs than skin, and water then washes the bonded germs down the drain. Proper handwashing for 30 seconds helps remove 99.9% of pathogens as it ensures full coverage and scrubbing to detach bacteria. While hand sanitizers kill germs quickly, handwashing with soap is superior for skin health due to alcohol content in sanitizers.

    I will be talking and explaining about soap and how it cleans our hands. In our recent

    pandemic, hand washing has become just as important as brushing our teeth or taking a shower;

    even more so, since you are asked to do it as frequently as possible. We are told that hand

    washing takes away the germs and keeps us protected from the coronavirus, but how can water

    and some soap protect us from a virus that has killed 5.66 million people worldwide. I am here

    to not only solidify your belief and trust in soap but to also help non-believers to protect

    themselves and others.

    There are not much physical properties of soap. You place the liquid soap or the bar soap

    in your hand. Add water to activate the soap suds which is almost always white not matter the

    color of the soap. You rub your hands together for 30 seconds minimum and then rinse with

    water and you’re all done. How can something so effective be that quick. Soaps have many

    chemicals that remove the pathogens from your hands. This is how it works. Soap molecules

    have two ends: hydrophilic, attracting water, and hydrophobic, repelling water.  First, the

    hydrophilic ends of the soap molecule attach to the water, then the hydrophobic ends attach to

    the oils, pathogens, or other debris on the hand. After the soap has bonded with the germs on

    your hand the water can then wash it down the drain. This works because the soap molecule can

    attach to the germs more strongly than the germs can hold onto your skin. Soap is powerful, but

    it cannot do all the work on its own. The amount of time you are rubbing your hands together

    and lathering up plays a massive role in handwashing efficacy. If you scrub your hands for just
    15 seconds you remove about 90% of pathogens, but with an additional 15 seconds, you are

    removing 99.9% of pathogens. This extra time ensures your entire hand is covered and allows

    the scrubbing motion to detach bacteria from your hands and be picked up by the soap and water.

    The option to kill germs using a hand sanitizer seems like the best option at first glance. But

    there are a few things that make handwashing with soap and water superior to alcohol-based

    sanitizers. Alcohol can be detrimental to skin health. The overuse of sanitizers can cause

    dehydrated skin much quicker than over washing of hands due to alcohol content. An important

    piece of hygiene is maintaining healthy, moisturized skin.

    I enjoyed learning about soap and how it deals with pathogens especially in this

    pandemic where I can offer proof and information to those that struggle to understand the

    seriousness and effectiveness of using soap to wash your hands.
