Does Unopened Hydrogen Peroxide Expire
On whether unopened hydrogen peroxide will expire
There is a thing in the world called hydrogen peroxide, which is used in medicine and cleaning. People often doubt that unopened hydrogen peroxide has a constant quality, and it is suppressed from expiring?
Those who have hydrogen peroxide are naturally active. Although unopened, it changes over time, and it also gradually changes. In the bottle, the molecules in it are constant, and they react when they encounter temperature changes and light exposure. High temperature, fast reaction; light exposure, decomposition speed.
The standard of hydrogen peroxide in various cities has a period of quality. This is not a lie, but a reality. After this period, its effect may be reduced. If used for disinfection, the strength is not as good as the original, and the bacteria are difficult to kill.
However, unopened hydrogen peroxide is not completely useless. Its condition can be carefully observed. If it is colorless and clear, no odor is produced, or it can still be used for ordinary cleaning, its effectiveness will be inferior to that of the new one.
To sum up, unopened hydrogen peroxide will also expire. To ensure its effectiveness, store it in a cool and dark place, avoid high temperature and light exposure. When using it, check its shelf life, and use it with caution if it expires to avoid misuse.
