Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
Based on the available studies on biodegradation, N-(1,1,3,3-tetramethylbutyl)acrylamide is expected to be only partially biodegradable and therefore not readily biodegradable. The branching of the tert-octyl chain of N-tert-octylacrylamide is probably the major reason for the recalcitrance to biodegradation in the test and the environment. Products formed upon hydrolysis i.e. acrylic acid and some isomers of tert-octylamine are probably biodegradable. The first reaction step (hydrolysis) is therefore expected to be the rate limiting step. As the substance was found to be hydrolytically stable at pH 4, 7 and 9, further biodegradation testing in soil is not expected to provide additional information.
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.
