The World Health Organization wants the recipe to contain nine parts 99 percent isopropyl alcohol (also known as rubbing alcohol), a little amount of hydrogen peroxide and a moisturizing agent like glycerol or aloe vera gel.
Your own recipe could be gotten from aloe vera and 99 percent rubbing alcohol or you can get inspiration from the recipes shared online, just make sure the mixture is made of at least 60 percent alcohol. Anything less than that and it will not kill any germs, the Centers for Disease Control and Prevention has said.
Be aware that getting the concentration right is not just important for your sanitizer to be effective, it also has to happen to prevent any kind of harshness on your skin. Stay away from DIY concoctions if you do not want to be a victim of this.
Adding an emollient like aloe vera gel or glycerin will prevent the hand sanitizer from drying out your skin, and essential oils will make the mixture smell nice. According to the ratio recommended by the CDC, a homemade sanitizer made with 0.67 cups (161 milliliters) of isopropyl alcohol would use 0.33 cups (79 ml) of emollient.
Meaning, if your solution is two-thirds 91% isopropyl alcohol and one-third emollient, the alcohol content of the mixture will be 60.6% (91 times 2/3). For higher alcohol content, you are allowed to make a solution that’s three-fourths 91% alcohol and one-fourth emollient, producing a mixture with an alcohol content of 68% (91 times 3/4). Stored safely in a closed bottle, a homemade hand sanitizer will last for several weeks.
Please note that a hand sanitizer is no substitute for handwashing. The best way to keep germs, including coronavirus, away from you is by washing your hands for at least 20 seconds with soap and water.
Commonly touched surfaces such as door handles, shopping carts, phones, faucets, remote controls e.t.c can attract lots of potentially harmful microbes, which could be dangerous for your health right now. This can be worsened during cold, flu season, viral outbreaks, making cleaning of hands very important.
