NOTE:<\/strong> We describe how to make a hand sanitiser based on the WHO formula 2 described in this article:\u00a0WHO Recommended Handrub Formulations<\/a>. You can see another formulation here: Formula 1 Hand Sanitiser<\/a>.<\/p>\n

\"\"<\/p>\n

According to the WHO, alcohol-based hand sanitisers are the only hand sanitisers that work effectively and quickly against potentially harmful micro-organisms on the hands.<\/p>\n

MATERIALS:<\/strong><\/h2>\n

- Isopropyl Alcohol 99,8%<\/strong>. It is a colourless, flammable alcohol, with an intense odour and very miscible with water. Its chemical formula is C3<\/sub>H8<\/sub>O, as opposed to C2<\/sub>H5<\/sub>OH formula of ethanol (normal pharmacy alcohol). You can find it at Alquera<\/a>.
\n- Hydrogen Peroxide 3%<\/strong>. The hydrogen peroxide you can find in pharmacies\/supermarkets.
\n- Glycerine 98%<\/strong>. You can find it at Amazon<\/a> or in Alquera<\/a>.
\n- Canister<\/strong> (sterilised in boiling water)<\/p>\n

QUANTITIES TO BE MIXED FOR 1 LITRE OF DISINFECTANT<\/h2>\n

- 751 ml Isopropyl Alcohol 99,8%
\n- 42ml of Hydrogen Peroxide 3%
\n- 15ml of de Vegetable Glycerin<\/a>.<\/p>\n

WHAT ROLE DOES EACH COMPONENT PLAY?<\/h2>\n

The role of each component is the same, whether you choose the formula 1<\/a> or this formula 2 (the information shown is a translation of this WHO document): WHO Recommended Handrub Formulations<\/a><\/p>\n

ALCOHOL:\u00a0<\/strong><\/p>\n

Alcohol-based hand sanitisers are currently the only hand sanitisers that work effectively to inactivate a broad spectrum of harmful microorganisms. They are inexpensive and can be easily brought to the point of application.<\/p>\n

HYDROGEN PEROXIDE 3%.\u00a0<\/strong><\/p>\n

The small concentration of hydrogen peroxide in the formula is to remove contaminated spores in the solution. It is not an active component on the hands.<\/p>\n

VEGETABLE GLYCERIN<\/strong><\/p>\n

Glycerine is used as a humectant and moisturiser. Maintaining the % of glycerine is important as it increases the stickiness of the active component alcohol on the hands.<\/p>\n

OTHER INGREDIENTS<\/strong><\/p>\n

It is better not to add fragrances and other components in this formula.<\/p>\n
