The decomposition reaction shows that this compound is somewhat unstable
and will degrade into water and oxygen gas after it is opened.
Keep stored in dark containers and in a dark location to slow down this decomposition reaction.
 

Hydrogen peroxide (H

) is the simplest peroxide (a compound with an oxygen-oxygen single bond). It is also a strong oxidizer. Hydrogen peroxide is a clear liquid, slightly more viscous than water. In dilute solution, it appears colorless. Due to its oxidizing properties, hydrogen peroxide is often used as a bleach or cleaning agent. The oxidizing capacity of hydrogen peroxide is so strong that it is considered a highly reactive oxygen species. Concentrated hydrogen peroxide, or 'high-test peroxide', is therefore used as a propellant in rocketry. Organisms also naturally produce hydrogen peroxide as a by-product of oxidative metabolism. Consequently, nearly all living things possess enzymes known as catalase peroxidases, which harmlessly and catalytically decompose low concentrations of hydrogen peroxide to water and oxygen.

Can be used for many useful purposes and can be used to decontaminate medical equipment without the ill effects of household bleach.  Can be purchased at most drug stores in 3% and 6% solutions and does come in 35% commercial concentrations from chemical supply houses.
