When choosing rubbing alcohol for personal hygiene, you may come across two common types: ethyl alcohol (ethanol) and isopropyl alcohol (IPA). Both can effectively disinfect, but which one is better for applying to your skin?
For everyday personal use, 70% ethyl alcohol is an excellent choice. It is commonly used in hand sanitizers and rubbing alcohol products and is generally suitable for disinfecting intact skin. It can also be a little more comfortable for frequent skin use than isopropyl alcohol, although either type can cause dryness with repeated application.
70% isopropyl alcohol is also effective on skin and is widely used as a disinfectant. However, it can be quite drying, particularly when used frequently. Isopropyl alcohol is especially useful for other purposes, such as cleaning electronics and removing grease or residue.
The 70% concentration is important. Alcohol that is too concentrated isn't necessarily better for disinfection. The presence of water in a 70% solution helps the alcohol work effectively against many microorganisms and allows it to remain on the surface longer.
If you're buying alcohol specifically for hands or occasional application to intact skin, 70% ethyl alcohol is a simple and practical choice. Look for products clearly labeled for use on skin and follow the manufacturer's instructions.
One important reminder: rubbing alcohol is not meant to be consumed, even when it contains ethyl alcohol. Some products are denatured or contain other ingredients that make them unsafe to drink.
In short, both ethyl and isopropyl alcohol can be useful disinfectants, but for everyday personal skin use, 70% ethyl alcohol is a convenient option. If frequent use causes dryness or irritation, consider using an appropriate alcohol-based hand sanitizer containing moisturizing ingredients instead.
