Description of key information
Additional information
Methacrylic anhydride, like other anhydrides of organic acids, hydrolyses in an aqueous environment with a half-life in the order of minutes resulting in two molecules of methacrylic acid per molecule methacrylic anhydride. As a consequence, instead of performing new studies, methacrylic acid studies have been used in many places of the assessment to describe the fate and effects of methacrylic anhydride.
Methacrylic acid is readily biodegradable, does not absorb to organic matrices and has no appreciable bioaccumulation potential.
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.
