Does 35% Hydrogen Peroxide Expire?

Hydrogen peroxide is a compound that decomposes quickly and is relatively unstable. When sealed in a container, 35% hydrogen peroxide will last for about three years. Nonetheless, on opening the container, the breakdown of the compound begins. From when you open it, the effectiveness lasts for six months. As you use it, ensure that the liquid in the bottle does not contact your body or other materials. Dipping a rag or finger, for example, accelerates the decomposition.

There is a simple and safe trick that does not take a lot of time that can help you determine whether or not your hydrogen peroxide is still good to use. Take the 35 hydrogen peroxide and pour some of it onto your sink. If it begins fizzing and bubbling, then the solution is good to be used. On the other hand, if there is no visible reaction, then the chemical is spoiled. On expiration, hydrogen peroxide gradually turns into water, hence no bubbling or fizzing when exposed to air.

Hydrogen peroxide does not have noticeable signs of spoilage by smell or sight, in the form of texture or color change. There are also no sediments or other similar evidence of spoilage. The solution can last longer if the bottle is sealed and stored in accordance with package recommendations. Because the solution has additional oxygen molecules, it is highly unstable and water begins dissociating following its production. The efficiency of hydrogen peroxide reduces with time and therefore requires replacement over time.

The shelf life of 35 food grade hydrogen peroxide solutions can be extended by maintaining it in the original opaque or dark-colored bottle. It is recommended to store it in a cool and dark location or refrigeration. To extend the lifetime of hydrogen peroxide, store it in cool, dark places. Avoid opening the bottle unless you need to use the solution. After three years, replace the bottle with a new 35% hydrogen peroxide solution bottle from The 1 Minute Miracle.
