Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- JUSTIFICATION FOR DATA WAIVING
Studies on soil organisms are not deemed necessary for both calcium peroxide and calcium hydroxide. On the one hand, calcium peroxide hydrolyses to calcium hydroxide and hydrogen peroxide when it comes into contact with moist. On the other hand, calcium hydroxide reacts with carbon dioxide in the environment to form calcium carbonate, which is one of the most abundant minerals in the earth's crust. Hydrogen peroxide is a short-lived substance in soil and ground water, because a rapid degradation will occur due to high concentration of catalytic material (transition metals, enzymes, easily oxidised/reduced organic substances and microbes) available. Hydrogen peroxide is decomposed to form water and oxygen, both compounds of no concern.

Additional information
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.
