Do Hand Disinfectants Expire? What You Should Know?

Hand disinfectants are effective in preventing infections. In the past years, they have gained popularity as an alternative to the water-soap method. But, is it ok to use a hand gel disinfectant that’s lying on your bedroom shelf for a long time? Will it be effective in killing all the germs? Let’s discuss.


Do Hand Disinfectants Expire?

The short answer is yes. So, it’s important to check the label carefully when buying a hand disinfectant.

How does a hand disinfectant expire? Alcohol-based hand gel disinfectants have isopropyl or ethanol as a primary component. Additionally, they contain water or glycerin, which prevents skin dryness.

Alcohol evaporates when it comes in contact with the air. Since disinfectants don’t come in air-tight bottles, the alcohol evaporation process starts after removing the seal. Over time, alcohol concentration in a hand gel disinfectant reduces, thus making it less potent.

Do Expired Hand Disinfectants Still Work?

Expired hand disinfectants are less potent, still they may be effective in killing some germs. There’s no harm in using a disinfectant after its expiration date. But, it won’t be as effective in eliminating germs as a fresh hand sanitizer spray.

Isopropyl alcohol in sanitizers is highly flammable, and can easily ignite. So, if you have an expired hand gel disinfectant, don’t throw it away. Dispose it safely instead. Follow your jurisdiction’s policies for disposing of flammable liquids.

How to Use a Hand Disinfectant Effectively?
