Hand sanitizers are designed and formulated to be used as an antiseptic for hands, and they often contain high levels of alcohol to effectively kill germs and bacteria. Attempting to extract alcohol from hand sanitizer can lead to unsafe concentrations, and it may also involve handling toxic or flammable substances.
If you need alcohol for other purposes, it is essential to obtain it from safe and legitimate sources. Isopropyl alcohol and ethanol (the types of alcohol found in hand sanitizers) can be purchased in pure forms from various suppliers or pharmacies. Always follow the instructions and safety guidelines when handling any chemicals.
Additionally, Costco or any reputable retailer would not encourage or endorse such activities. It is essential to use products for their intended purposes and to prioritize safety and health above all else. If you need alcohol for a specific use, it's best to purchase it from a reliable source and use it as intended.
