====== Hydro-alcoholic solution ======
  * [[https://fr.wikipedia.org/wiki/Solution_hydro-alcoolique|Hydro-alcoholic solution]] (called SHA)
  * Protocol to fabric the solution by World Health Organization (WHO)

| |  **10 L**  |  **1 L**  |  **100 mL**  |
|Alcohol (ethanol 96°)* |  8,333 L  |  833 mL  |  83 mL  |
|Hydrogen peroxyde (3 %) |  0,417 L  |  42 mL  | 4,2 mL  |
|Glycerol 98 % |  0,145 L  |  14 mL  |  1,4 mL  |
|Clean water (distiled, boiled and frozen) |  q.s.p.  |  q.s.p.  |  q.s.p.  |

* One can use isopropanol at 99,8 % (7,515 L for a final solution of 10 L). 

  * To wash your hands properly, apply [[en:subject:prevention:wash_hands|five movements]]! 
  * The question asked directly to Prof. D. Pittet (the inventor of the SHA) to know the minimum ethanol concentration: " __It is advisable to use a hydro-alcoholic solution with a minimum concentration of 60% alcohol, ideally 75% to 80%__ " Which means that if you only have at your disposal alcohol at 70° (for example camphorated alcohol), then you can make your SHA without adding water : 100mL of 70° alcohol + 5mL of H2O2 and 2mL of glycerol gives a final alcohol concentration of about 66.5°. The WHO formulation says to let it rest for 3 days (but well, after 24 hours, the effect of H2O2 is clearly diminished on the skin, in fact).
