Why is Hydrogenperoxide is kept in green bottle?

Hydrogen peroxide is stored in green or dark-colored bottles to protect it from light exposure, which can cause it to degrade and lose its effectiveness over time. Light, particularly UV light, can break down hydrogen peroxide into water and oxygen, resulting in a reduction of its concentration and efficacy as a disinfectant or bleaching agent. The colored bottles help maintain the stability and shelf life of the solution.
