Does hydrogen peroxide expire

Most of us are familiar with the word “expiry” which is defined by Oxford Dictionaries as “the end of the period in which something is valid.” However, manufacturers have come up with a list of other terminologies, which is useful to know when managing expired products. Here are some of the more widely used terms used:

 

Expiration or shelf-life dated product: This is a product that is expected to meet its specified properties only when stored under manufacturers’ defined conditions.

 

Recommended retest dated product: This is essentially the same as an expiration dated product. The catch is, however, that the expiration date may be extended following a retest and review of the product’s quality.

 

Product without retest or expiration dates: This is a product with no indication that it can become unstable, but product retest is recommended every few years for quality control.

 

What is hydrogen peroxide?

Hydrogen peroxide is a mild antiseptic used on the skin to prevent infection of minor cuts, scrapes, and burns. It may also be used as a mouth rinse to help remove mucus or to relieve minor mouth irritation (such as due to canker/cold sores, gingivitis).

This product works by releasing oxygen when it is applied to the affected area. The release of oxygen causes foaming, which helps to remove dead skin and clean the area. This product should not be used to treat deep wounds, animal bites, or serious burns.

Hydrogen peroxide is active against a wide range of microorganisms, including bacteria, yeasts, fungi, viruses, and spores. A 0.5% accelerated hydrogen peroxide demonstrates bactericidal and virucidal activity in 1 minute and mycobactericidal and fungicidal activity in 5 minutes.

 

How to use Hydrogen Peroxide Solution

Does hydrogen peroxide expire

Does hydrogen peroxide expire?

Yes, According to Healthline, hydrogen peroxide expires and becomes less and less effective over time. In fact, it starts to decompose even before you open it. In a closed container, it’ll eventually break down into water and oxygen gas.

When the oxygen gas escapes through the top of the container, only water is left in the container. Of course, water isn’t an effective household cleaner or disinfectant.

An unopened container of hydrogen peroxide will last for around 3 years, but as soon as it’s opened, it’ll expire within 6 months.

You can check to see if hydrogen peroxide is still good by pouring a small amount down the sink and looking to see if it bubbles or fizzes. If it doesn’t cause this reaction, it’s likely no longer good.

 

Can you use expired hydrogen peroxide?

No, manufacturers do not guarantee that hydrogen peroxide strength after the expiration date is the same as before. Expired hydrogen peroxide does not necessarily pose an immediate health risk but it can fail to provide a proper antiseptic effect when used. But it has its initial effect. For this reason, it may not kill many germs or prevent infection effectively.

 

Can expired hydrogen peroxide cause side effects?
