While hand sanitizer, rubbing alcohol, and methylated spirit all contain alcohol and act as disinfectants, they have distinct compositions, strengths, and safe application uses.
Hand sanitizer is specifically formulated for human skin hygiene. It typically contains 60% to 95% ethanol or isopropyl alcohol, blended with emollients like aloe vera or glycerin to prevent the skin from drying out.
Rubbing alcohol is a first-aid staple, most commonly made of 70% isopropyl alcohol. It contains a small amount of water, which actually improves its ability to penetrate and kill germs.
Methylated spirit is ethanol that has been rendered toxic and unpalatable by adding chemicals like methanol, pyridine, and often a purple dye. Because of its toxicity and harshness, it should never be used as a hand sanitizer or applied directly to the skin.
