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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Studies with fish, daphnia and algae as well as with aquatic microorganisms are available and thus, the PNECs are based on the test results and assessment factors recommended in the Technical Guidance Document (ECHA, 2008) have been applied. For the compartments sediment and soil, no studies have been conducted and the PNECs have been calculated using the Equilibrium Partitioning Method as screening values. Tests with sediment and terrestrial organisms are not mandatory according to Regulation (EC) No 1907/2006. The PNEC oral is derived from a toxicological endpoint as the toxicity towards birds has not been tested because it is not necessary according to Regulation (EC) No 1907/2006 as well.
Conclusion on classification
Daphnia was found to be the most sensitive aquatic species. The EC50 (48 h) is 69 mg/L and the substance is not readily biodegradable. Thus, UAX-1179 is classified according to Directive 67/548/EEC as R52/53 and according to GHS Regulation (EC) No 1272/2008 as chronic category 3.
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.
