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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Generally, the substance is not supposed to be directly applied to soil and further is readily biodegradable. Hence in case of indirect exposure to soil, the substance is expected to rapidly degrade. Therefore soil is not expected to be a compartment of concern and the risk to terrestrial organisms is regarded to be negligible.
Nevertheless a long-term toxicity test with soil macroorganisms (earthworms, OECD 222) is available. No Observed Effect Concentration (NOEC) for mortality, growth, reproduction and feeding activity of the earthworm Eisenia fetida was determined to be 1000 mg test item/kg soil, i.e. the highest concentration tested. Based on the results of these studies, it can be concluded that Betaines, C12-14 (even numbered)-alkyldimethyl have a low impact on terrestrial macroorganisms.
Additionally, the bioaccumulation potential is low and the test substance is considered to cause low hazard to predators. Thus, a study with birds is not needed due to animal welfare reasons.
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.
