- JUSTIFICATION FOR DATA WAIVING
Components of the substance like calcium carbonate and silicates are inorganic and are expected to have a low potential for adsorption to sediment. They do not undergo biodegradation i.e. microbial degradation to carbon dioxide and water. Calcium carbonate will be degraded in the environment by means other than biodegradation. The ions will dissociate; calcium will be assimilated by species in the water and is necessary to maintain a good chemical balance in soils, water and plants and carbonate will become part of the carbon cycle. Calcium carbonate is a commonly occurring substance in the environment. Silica /silicates are one of the most abundant materials in earth´s surface and calcium silicate is an inorganic, stable/inert compound which is not biologically transformed. A sediment simulation test for the substance is therefore scientifically not justified.

Applicant's summary and conclusion
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.
