Make the hydroalcoholic gel at home

You need alcohol that kills viruses and bacteria, hydrogen peroxide (or hydrogen peroxide) that eliminates the bacterial spores potentially present in the bottles but which has no antiseptic action on the skin, and glycerol that acts as an emollient and humectant. Other softeners can be used as a replacement for glycerol, such as aloe vera. All these ingredients are available on request at the pharmacy.

Attention: the WHO specifies that only products specifically intended for pharmaceutical use (and not industrial products) must be used. Hydrogen peroxide is also corrosive at concentrations higher than 3-6%. Also be wary of alcohol bottles sold commercially, whose concentration is often lower than 70%.

Here are the quantities to obtain one liter of hydroalcoholic solution: 833 ml of alcohol (ethanol 96% or isopropanol 99.8%); 41.7 ml of oxygenated water (hydrogen peroxide 3%); 14.5 ml of glycerine (glycerol 98%); distilled water or slurry to complete.

The manufacturing steps of the hydroalcoholic gel

The proportions may vary slightly, but the alcohol concentration must remain above 60%; the higher the alcohol concentration, the more effective the hydroalcoholic solution will be. Pour the alcohol into a graduated container. Add hydrogen peroxide, then glycerol (the latter being viscous, part of the distilled water can be used to rinse the container with which it was poured). Make up with remaining distilled water. Immediately divide the solution into several tightly closed vials to prevent evaporation. Wait at least 72 hours before using the hydroalcoholic gel so that the hydrogen peroxide works. Remember to properly label the bottles and keep them out of the reach of children.
