Hydrogen Peroxide Shelf Life After Opening
On the valid period of hydrogen peroxide after opening
Hydrogen peroxide, the chemical name hydrogen peroxide, is widely used in medical, industrial, and daily fields. However, after opening, the geometry of the valid period is often confused.
Hydrogen peroxide is active, and it is easy to decompose into water and oxygen when exposed to light, heat, impurities, etc. When sealed, because it is isolated from the outside world, the decomposition is slow, and the valid period can be longer. However, once opened, it is connected with the external environment, and many factors cause its decomposition to accelerate.
Generally speaking, after opening the hydrogen peroxide, if it is properly stored in a cool, dry, and dark place, and the container is well sealed, it can be kept for more than a month. If the environment is not good, such as warm, humid, light, or the container is not properly sealed, the valid period will be greatly reduced, or only 10 days can be maintained.
In medical hydrogen peroxide, it is related to the health of patients, and it is necessary to pay more attention to the valid period. Expired hydrogen peroxide, its disinfection and sterilization effect is greatly reduced, not only can not achieve the expected effect, or cause increased risk of infection.
In industrial and daily use, expired hydrogen peroxide may also affect the use effect. If used for bleaching, its bleaching power or insufficient; for cleaning, decontamination work or not enough.
Therefore, after the hydrogen peroxide is opened, the user should check the storage conditions and roughly judge the valid period according to its condition. It is also advisable to observe its properties carefully before use. If there is any abnormality such as discoloration and odor, even if it does not exceed the approximate valid period, it should not be reused to ensure safety and effect.
