Description of key information
Additional information
Magnesium hydroxide has a very low solubility in water (1.78 x 10^-3 g total solids/L) and any Magnesium hydroxide dissolved is dissociated completely. As no equilibrium is formed no dissociation constant can be determined and thus the study was not conducted. Magnesium hydroxide will not bioaccumulate or adsorb to sediment based on the derived Kd value of 1.65 and as a result, this study is not required.
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.
