Hand Sanitizer Project

Last week me and my sister made hand sanitizers. We can cooperate well and work together to finish making all of them on time.

Hand sanitizer has to have at least 70% alcohol. So, I made it by mixing 1 liter of 96% alcohol and 300mg of aloe vera. With that mixture, it will create 1000/1300 x 96% = 74% alcohol in each bottle.

I mixed 5 liters of alcohol and 1.5 liters of aloe vera. So the total are 6.5 liters.


  1. Prepare 1 liter 96% alcohol and 300mg aloe vera
  2. Pour them together in a clean container and mix it well.
  3. Divide the hand sanitizers in small bottles (60ml/bottle)
  4. Label the bottles “Hand sanitizers”
  5. Ready to be distribute it

After finish filling all the sanitizers, we label the bottles

Here is the finished hand sanitizer that we make:

Hand sanitizers are ready to be distributed to people needed

We gave it to Gojek or Grab that come to our house

We gave it to people around my house (small stall, gojek that are waiting for order in the stall near my house, becak, kiosk in front of the church that I often meet)
