Hand sanitizers were invented by Lupe Hernandez, a registered nurse in Bakersfield, California, in 1966.
The story goes that Hernandez was a nurse student when she realized alcohol delivered through a gel could clean hands in a situation where there was no access to soap and warm water. After learning that her idea had a lot of potential commercially, she called an inventions hotline to find out more information about the process.
The global hand sanitizer market size was valued at $919 million in 2016, it was valued 2.7 billion in 2019. But on the first week of March 2020, hand sanitizer sales shot up by 470% compared to the same week a year earlier.
As novel coronavirus (COVID-19) fears grow, hand sanitizer continues to sell out in local drugstores and online across the globe.But not many people use hand sanitizers correctly. They just dab a little hand sanitizer on their hands, rub for a second, and go about their day, but that’s actually not the correct way to use it.
Instead, the CDC specifically recommends putting sanitizer on your hands, covering them in sanitizer, and rubbing them together until they’re dry, which will likely take about 20 seconds.
You’ll also want to make sure you’re using alcohol-based hand sanitizer that’s between 60 to 95% alcohol, Dr. Cennimo says. These products usually contain ethyl alcohol (ethanol) and isopropyl alcohol.
You can make your own hand sanitizer , just make sure that the tools you use for mixing are properly sanitized; otherwise you could contaminate the whole thing
Aloe vera gel
Tea tree oil
Mix 3 parts isopropyl alcohol to 1 part aloe vera gel. Add a few drops of tea tree oil to give it a pleasant scent and to align your chakras.
Keep in mind ,hand sanitizer can help protect you from coronavirus, but it should not be considered your first line of defense against COVID-19. “Hand washing with soap and water and scrubbing for at least 20 seconds is recommended, but a hand sanitizer that contains at least 60% alcohol is the best alternative,” says Richard Watkins, M.D., infectious disease physician and professor of medicine at Northeast Ohio Medical University.
