According to WHO hand sanitizer recipe guidelines, 240 ml of Isopropyl Alcohol 99% added to 15 ml of hydrogen peroxide 3% and 5ml of glycerin and 60ml of distilled water will make a great 75% alcohol.
In this recipe, I only used half of that measurement to keep the sanitizing spray fresh.
Here is the measurement I used in the video demonstrated on my YouTube Channel @SkincareQueenTV
- Isopropyl Alcohol 99% – 120ml
- Hydrogen Peroxide 3% – 7.5ml
- Glycerin – 2.5ml
- Distilled water – 30ml
WHO HAND SANITIZING SPRAY PREPARATION METHOD
