Why is Soap Important For Washing Hands?

We all are using soap a lot these days. But, how does it really work? Well, there are tiny pin-shaped molecules in soap. Those pin-shaped molecules have two parts to them: the hydrophilic head and the hydrophobic tail. Hydrophilic means that it bonds or mixes with water and hydrophobic means that it is repelled by water. The hydrophobic head is attracted to oils and fats on your skin and the hydrophilic tail is attracted to water. When you was your hands and scrub for 20 seconds, the molecules lift the dirt and germs away and carries it with the water, down the drain. It is important to scrub soap for 20 seconds because that is how long it takes for the soap to fully clean your hands! Soap helps get rid of germs and dirt so that your hands are clean!
