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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
No well-documented data are available for chronic toxicity of reaction mass of C12 trimethylammonium bromide and C14 trimethylammonium bromide to fish.
Key value for chemical safety assessment
Additional information
Study is scientifically unjustified and disregarded based on the following:
1. In the aquatic environment, reaction mass of C12 trimethyl ammonium bromide and C14 trimethylammonium bromide is expected to strongly adsorb to particles.
2. When present in low concentrations in the water phase, reaction mass of C12 trimethyl ammonium bromide and C14 trimethylammonium bromide is expected to be biodegraded.
3. Reaction mass of C12 trimethyl ammonium bromide and C14 trimethylammonium bromide has a low potential for bioaccumulation
4. Crustaceans and algae are more sensitive organisms to reaction mass of C12 trimethyl ammonium bromide and C14 trimethylammonium bromide than fish. Chronic toxicity to crustaceans is therefore more representative for long term effects of reaction mass of C12 trimethyl ammonium bromide and C14 trimethylammonium bromide in the aquatic environment. Reference is made to unpublished data reporting a chronic NOEC for fish for the substance dodecyltrimethylammonium chloride of 0.46 mg/L . No details were given so the value can only be used as an indication of the level of chronic toxicity for reaction mass of C12 trimethyl ammonium bromide and C14 trimethylammonium bromide to fish to be below the mg/L range.
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.
