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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
No genotoxic activity was noted in an array of in vitro and in vivo studies. Dodecanedioic acid was not genotoxic in microbial and mammalian in vitro mutagenicity assays, both in the presence and absence of metabolic activation. Also no genotoxic effect was observed in the murine bone marrow micronucleus test in vivo. An additional study on the clastogenic activity in vitro is considered not necessary.
Short description of key information:
No mutagenic activity was noted with or without metabolic activation in two studies using microbial test systems and in a study using mammalian cells. No clastogenic activity was noted in vivo in a murine bone marrow micronucleus test. No genotoxic effects in Chinese hamster V79 cells in the presence or absence of metabolic activation was observed for the read across test substance dodecanedioic acid under the conditions of the study.
Endpoint Conclusion: No adverse effect observed (negative)
Justification for classification or non-classification
Dodecanedioic acid was not genotoxic in vitro and in vivo, therefore classification is not required.
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.
