Applicant's summary and conclusion
- Executive summary:
The following text is copied from the EU risk assessment carried out for hydrogen peroxide:
"Direct photolysis is not expected to be an important degradation process in the aquatic environment. Hydrogen peroxide has absorption bands in the infrared, but is not decomposed by the light of these frequencies. The UV absorption spectrum is a continuous spectrum but the measured molar extinction coefficient values are low. Highest value is ∈ = 4.2 l/mole.cm (at 280 nm) decreasing continuously to 0.22 l/mole.cm (at 320 nm) and 0.00066 l/mole.cm (at 400 nm) (Schumb et al., 1955)."
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
