Description of key information
MTDID 44430 is inherently biodegradable but does not fulfill specific criteria.
Additional information
MTDID 44430 did not meet pass criteria for ready biodegration nor specific criteria for inherent biodegradation. It is not toxic to biodegradation. In the inherent test, the test material could not be measured in inoculum blanks at the end of the test. The result was considered conservative, in that the substance may not have been entirely available to biodegradation throughout the test period. The expected degradation pathway is hydrolysis of the acrylate ester functionality followed by oxidation of the secondary alcohol to form a mixture of dodecyl ketones. This assumption leads to equivocal results. Acrylic acid is readily biodegradable. Undecan-2-one is not readily biodegradable (test conducted at four times the solubility limit), while nonan-2-one is easily biodegraded (test conducted at <2% of solubility limit). It is possible that the undecan-2-one did not pass its ready biodegradation test due to lack of solubility. The ultimate biological fate of MTDID 44430 is not entirely characterized.
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.
