Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A read-across of Corfree® M1 (consisting of46 wt% Dodecanedioic acid, 31 wt% Undecanedioic acid, 5 wt % Sebacic acid and 11 wt% other dibasic acids) with dodecanedioic acid indicates that it has been used experimentally in both parenteral and oral clinical alimentation studies. No adverse effects were reported at dose levels of up to 40g per person.
In an isolated case report occupational asthma was associated with exposure to soldering fumes from dodecanedioic acid containing flux.
Additional information
The major ingredient in Corfree® M1, Dodecanedioic acid, is rapidly and completely absorbed from the gastrointestinal tract. It is metabolised and incorporated in the fatty acid catabolism of the organism and has been proposed to be an intermediate in the beta-oxidation of long-chain fatty acids. Dodecanedioic acid is not or only to a small extent excreted renally. Dodecanedioic acid is devoid of any systemic adverse effects upon acute or repeated dosing. One single casuistic of occupational asthma was linked to exposure to decomposition fumes of dodecanedioic acid in soldering flux but the medical history of this isolated case is unclear.
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.
