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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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
Additional information
The QSAR calculated rate constant for the OH sensitized photodegradation of dodecanedioic acid is approximately 1.41E-11 cm3/(molecule * s) (AopWin Computer Program, Vers. 1.92, integrated in U.S. EPA's EPI program Vers. 4.1). At 500,000 OH radicals / cm3, this corresponds to a half-life of 27.4 hours.Dodecanedioic acid and its structural analogs are not expected to be persistent in the atmosphere. This means that the components of Corfree® M1 diacids are not expected to be persistant in the atmosphere.
Corfree® M1 is not expected to hydrolyse, but it is readily biodegradable. Persistence and accumulation in water is not expcted to occur.
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.
