Sift the carbopol in a container.

In a bottle with a codifying cap add the ½ liter of boiled distilled or bottled water, then add the sifted carbopol, cover the bottle and shake vigorously until no lumps are observed.

Pour the ½ litre ethyl alcohol 70 degrees GL, close the cap and shake until the ingredients are incorporated.

Finally, add the teaspoon of triethanolamine and shake until the right consistency is obtained.


Domestic antibacterial gel technology has a one-year shelf life.


Store in a cool and dry place to avoid evaporation of the alcohol, which kills germs and microbes.

Does the anti-bacterial gel work against covid-19?

Use antibacterial gel or wash your hands? That's the question many people are asking themselves with the spread of COVID-19 coronavirus. Because of fears of contagion, antibacterial gels, also called hand sanitizers, have become prized products. Demand has skyrocketed worldwide and some pharmacies have announced that they are rationing sales of these products.

How effective are hand sanitizers against coronavirus infection?

Both the UK's National Health Service (NHS) and the US Centers for Disease Control (CDC) stress that the best way to prevent disease is to avoid exposure to the virus. And for them, a number of preventive measures should be followed, such as covering your mouth with a tissue when you cough or sneeze and disposing of the tissue in the trash.

Health agencies also recommend washing your hands often with soap and water, especially after using the bathroom, before eating and after blowing your nose, coughing or sneezing. This handwashing should last at least 20 seconds and the soap should cover the palms and backs of the hands and between the fingers, including the thumb.

And about the role of antibacterial gels, here's what the CDC says:

"Use hand sanitizer when soap and water are not available."

And they add: "Handwashing with soap and water is the best way to get rid of germs in most situations.

"If soap and water are not available, you can use an alcohol-based hand sanitizer that contains at least 60% alcohol.

"You can tell if the hand sanitizer contains at least 60% alcohol by looking at the product label," the body says.

CDC recommendations on how to wash your hands

Always follow these five steps:

1. Wet your hands with clean running water (warm or cold), turn off the tap and soap your hands.

Rub your hands with the soap until they lather. Rub the lather on the back of your hands, between your fingers and under your nails.

3. Rub your hands together for at least 20 seconds. Do you need something to time it? Hum the "Happy Birthday" song twice from beginning to end.

4. Rinse your hands well under clean running water.

5. Dry them with a clean towel or in the air.

Temporary measure

Experts say that sanitizing gels can reduce the number of germs on hands in many situations. But these products do not get rid of all types of germs, such as chemicals like pesticides and heavy metals.

In the case of coronavirus, they can be effective, but only as a temporary measure, while you have access to soap and water. If you do not have immediate access to soap and water, use an alcohol-based hand sanitizer.

How do you apply the hand sanitizing gel?

The CDC recommends applying the product to the palm of one hand and rubbing both hands together. The gel should be applied to all hand and finger surfaces until the gel has dried. This should take approximately 20 seconds.

Panic buying

In Mexico, one of the countries where demand and prices for disinfectant gels have skyrocketed, authorities are advising people not to "panic" about buying antibacterial gels.

As that country's undersecretary of health, Hugo Lopez-Gatell, said at a press conference this week, "at this time it is important not to fall into the myths" of what works or does not work.

"You don't have to have extraordinary measures of having to buy a whole stock of aerosol disinfectants, tons of chlorine, or new molecules, there is no use either," he said.

The best way to take care of this virus, the official said, is to maintain hygiene and follow the recommendations of the authorities.
