Is there an expiration date for isopropanol?

Yes, isopropanol (isopropyl alcohol) does have an expiration date, which is typically indicated on the packaging. Over time, its effectiveness can diminish, especially if it is not stored properly. While it may not become harmful, its potency as a disinfectant or solvent can decrease, making it less effective for its intended use. Always check the label for specific storage instructions and expiration information.
