Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 276-431-5 | CAS number: 72162-23-3 The high-boiling fraction separated by distillation from the products obtained from the reaction of nitric acid with cyclododecanol and cyclododecanone. Composed primarily of dodecanedioic acid, undecanedioic acid, and sebacic acid.

Description of key information
Simulation testing for biodegradation in soil is not required as Corfree® M1 diacids is identified as readily biodegradable (refer to IUCLID point 5.2.1 / REACH regulation data point 9.2.1.1). Therefore, a test is not required according to REACh Annex IX, column 2.
Key value for chemical safety assessment
Additional information
Waiving according to "column 2" in Annex IX of REGULATION (EC) No 1907/2006 (substance readily biodegradable). The substance was found to be readily biodegradable when tested according to OECD 301b (CO2 Evolution) guidelines, but failed the 10-day window. Because it is a complex chemical mixture of homologus components, the 10-day window does not apply.
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.
