What is the shelf life of commercial solutions of hydrogen peroxide?
Evonik hydrogen peroxide grades have excellent shelf life. If stored at an average temperature of 20°C, decomposition is less than 2% per year based on active hydrogen peroxide. A 50% solution would be at least 49% H2O2 after one year of storage. Storage at higher temperatures can accelerate the decomposition reaction, however, actual experience shows that even lightly stabilized grades of peroxide undergo much less than 2% decomposition over a number of years if properly stored.
