Description of key information
Additional information
Bioaccumulation is not relevant for calcium magnesium (di)hydroxide oxide. In the aquatic environment and in soil, exposure to calcium magnesium (di)hydroxide oxide actually comes down to exposure to calcium, magnesium and hydroxyl ions. There will be no intake of
calcium magnesium (di)hydroxide oxide as such from water or soil, nor will calcium magnesium (di)hydroxide oxide prevail under its original form in the organisms. Moreover, both the intake of the essential elements calcium, magnesium and the internal pH (hydroxyl ions) of an organism are actively regulated (homeostasis).
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.
