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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Toxicity to birds:
In an avian repeated dose toxicity study with Japanese quails the NOEL was determined to be 200 mg chlorine/L. The LOEL was 400 mg chlorine/L based on smaller but functional testes.
Waiving of other terrestrial toxicity studies:
In accordance with column 2 of REACH Annex IX and X, terrestrial toxicity studies (required in sections 9.4.X and 9.6.1) do not need to be conducted as the equilibrium partitioning method was applied to assess the hazard. The substance has no high potential to adsorb to soil and is not persistent. In addition, chlorine dissipates rapidly in contact with soil with a DT50 of < 1 minutes. Therefore, toxicological effects are not expected and consequently terrestrial toxicity testing is not necessary. Furthermore, the results of the chemical safety assessment do not indicate the need to investigate further the effects of the substance and/or relevant degradation products on terrestrial organisms.
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.
