Can you still use an expired alcohol gel to disinfect your hands?

Using expired alcohol gel can be problematic for the following reasons.

The effectiveness of alcohol gel in killing pathogens depends on the concentration of alcohol (usually 60% or higher). Over time, the alcohol in the gel can evaporate, causing the concentration to become too low to be effective. After the expiration date, the alcohol concentration in the gel may have decreased due to evaporation or chemical breakdown, making it less effective at disinfecting your hands.

The formulation of alcohol gel may change after the expiration date. Ingredients may degrade, which can affect the gel in terms of viscosity, odor, and effectiveness. Bacteria or mold may develop in the gel over time, especially if the packaging is not properly sealed. Using expired alcohol gel may increase the risk of inadequate hand disinfection. This can be especially important in situations where good hand hygiene is crucial, such as during disease outbreaks or pandemics.

Do not use alcohol gel after the expiration date stated on the packaging. This is a guideline from the manufacturer for the effectiveness and safety of the product. If the gel has changed color, has a strange smell or has changed texture, it is better not to use it, even if it is still within the expiration date. If you have alcohol gel that has expired, replace it with a new product that is within the expiration date and contains the recommended alcohol concentration.
