Additional information
Due to the rapid hydrolysis of magnesium ethanolate in water or soil moisture, the relevant species subject to environmental distribution are the degradation products magnesium hydroxide and ethanol. For the magnesium hydroxide it was concluded that it will be found predominantly in the aquatic compartment as alkali metal and hydroxide ions and will not adsorb on particulate matter or surfaces. For ethanol one can conclude that based on the Henry’s law constant of 0.575 Pa m3/mol it is not expected to significantly volatilize from the aquatic compartment and adsorption to soil is not expected to be significant due to its high water solubility and low octanol-water partition coefficient.
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.
