Shoppers have flooded to drugstores to stock up on hand sanitizer as the coronavirus outbreak in the United States has worsened, leaving shelves barren of the product for those who weren't quick off the mark.

How to make homemade hand sanitizer Place 2/3 cup of rubbing alcohol (Isopropyl alcohol) in a bowl Add 1/3 cup of aloe vera gel and mix well Add 5-10 drops of essential oil and mix again Ensure alcohol equals to 60% of mixture Use a funnel to transfer to a liquid soap container Ensure container is tightly sealed Ethanol can be used instead of rubbing alcohol Alternative non-alcohol methods swap one tablespoon of witch hazel and half a teaspoon of tea tree oil for the rubbing alcohol Advertisement

In the past week, demand for hand sanitizer has soared 1,400% with some stores limiting the amount of a customer can purchase at one time and others jacking up prices looking to make a profit off the global panic.

Amazon has banned 10,000 users for price gouging as the panic buying intensifies.

While public health experts are advising that routinely and effectively washing your hands with soap and water is the best way to warn off coronavirus germs, there are ways to make your own hand sanitizer for those times when you just can't get to a sink.

'Homemade hand sanitizers are just as effective as what you buy as long as you used the right percentage of alcohol,' Dr. David Agus told CBS MoneyWatch.

'This is a good way to get around people price-gouging for Purell.'

In order for any good home hand sanitizer to work, it needs to be compromised of at least 60 percent alcohol.

Recommended for use is rubbing alcohol (Isopropyl alcohol) while ethanol will also make a suitable variation.

In order to protect your skin, aloe vera gel is added to the rubbing alcohol and a few drops of essential oil will give it a nicer smell.

To make your own hand sanitizer, take 2/3 cup of rubbing alcohol and mix in a large bowl with 1/3 cup of aloe vera gel and 5-10 drops of the essential oil of your choice.

A two-ounce spray bottle or a liquid soap container can be used to hold the mixture to take on your commute or leave in your home or office.

If made properly and sealed tightly in its container, a homemade hand sanitizer can last for weeks.

'If you make it well, it's about as effective as using soap and water,' Dr. Stephen Morse, a professor of epidemiology at Columbia University in New York, told CBS.

'We know it works — just make sure it has enough alcohol in it.'

While health experts say that DIYers should ensure the solution is at least 60 percent alcohol, some claim an alcohol-free version can be made using witch hazel and tea tree oil.

If properly made and sealed, homemade sanitizer can be kept for several weeks

In this case, one cup of aloe vera gel should be mixed with one tablespoon of witch hazel, half a teaspoon of tea tree oil, a drop of vitamin E oil and a few drops of an essential oil.

The witch hazel is said to be a non-drying cleanser while tea tree oil will take on germs.

The Vitamin E oil is used to add moisture.

According to Miryam Warham, a biology professor at William Paterson University, hand washing is still the best method to rid yourself of germs. By washing your hands you are removing all germs from your skin.

Hand sanitizer aims to kill the germs but does not remove them.

'Handwashing is the most important first step, and you shouldn't be bashful about it,' Wahrman told Business Insider.

The death toll from the coronavisrus in the United States has now reached eleven people.

At least 137 people have been diagnosed.

Amazon says it has banned 10,000 sellers attempting to price-gouge on bottles of hand sanitizer and other cleaning products as stocks run low amid the coronavirus outbreak

There have now been over 3,200 deaths related to the virus globally and over 93,000 infected.

The Center of Disease Control continues to advise people to wash their hands regularly with warm water and soap for at least 20 seconds, or use alcohol-based hand sanitizer, to prevent the spread.

Hand sanitizer does not kill all viruses but is effective against the coronavirus.

On Wednesday, Amazon banned 10,000 users for price gouging and removed one million products for making spurious health claims amid the global coronavirus outbreak.

Unscrupulous online traders have tried to cash in on the health emergency as stocks of hand sanitizer and face masks have run low in stores amid panic-buying.

Two-packs of Purrell hand sanitizer, which typically sell for $12, were marked up at $119.99 on Amazon this week as people tried to protect themselves from the virus.

A company spokesman told ABC: 'There is no place for price gouging on Amazon.'
