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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Corfree® M1 has been assessed using the read across major ingredient, dodecanedioic acid (CAS Number: 693-23-2), as the most sensitive chemical to organism in acute toxicity tests from three trohpic levels is the alga species Desmodesmus subspicatus with an ErC50 of >38.6 mg/L. According to Guidance R.10 an assessment factor of 1000 is applied. All ecotoxicological endpoints were considered and the appropriate read across datawas used to derive the extrapolated PNECvalues.
Conclusion on classification
Directive 67/548/EEC:
Considering the available acute and chronic aquatic ecotoxicity data and the results from the biodegradation study the test substance is not environmentally classified.
GHS:
Based on the available acute and chronic aquatic ecotoxicity data and the results from the biodegradation study the substance is not environmentally classified.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
