I almost forgot be sure to label your dispensing container hand sanitizer 75% alcohol. in my first video available on March 3rd through March 4th I had the quantities of hydrogen peroxide and glycerin reversed. sorry for the error. if you made a batch as shown in the old video it will still work even though it does not precisely match the World Health Organization formula. the important part the final alcohol content is still correct at 75%
