Spritz. Rub. Go! We use a WHO recipe with 75% alcohol, hydrogen peroxide, glycerin (a natural humectant to help keep your skin from getting so dried out), and water. Made with a blend of Alcohol (Ethanol) 75%, Hydrogen Peroxide, Glycerol (Glycerin), and Aqua (Water). 2 fl oz While this formula is certified by the WHO, we have not had it re-certified in-house to label it a sanitizer. Our focus was to get a quality & effective product in & on your hands quickly!
