Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In Annex IX of Regulation (EC) No 1907/2006, it is laid down that toxicity testing on terrestrial species shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on soil organisms. In chapter 9 and 10 of the attached CSR it is clearly stated that the substance does not pose any threat to the environment. According to Annex I of this regulation, the chemical safety assessment triggers further action when the substance or the preparation meets the criteria for classification as dangerous according to Regulation EC 1272/2008 or is assessed to be a PBT or vPvB. The hazard assessment of CAS 1328-53-6 reveals neither a need to classify the substance as dangerous to the environment, nor is it a PBT or vPvB substance, nor are there any further indications that the substance may be hazardous to the environment. According to REACH Regulation (EC) No 1907/2017, Chapter R.7c, Table R.7.11 - 2 (soil hazard categories) the substance belongs to hazard category 1. Following this the screening assessment would be based on the EPM (Equilibrium Partitioning Method). However, since no hazard is identified and no PNECs are derived for the aquatic compartment based on acute effect values > 100 mg/L for the trophic levels fish, aquatic invertebrates and algae and chronic effect values > 1 mg/L for aquatic invertebrates and > 100 mg/L for algae) the EPM is not applied as no significant toxicity for the soil compartment is expected. Consequently, no tests on terrestrial organisms are provided.


In addition, experimental data available for soil macroorganisms except arthropods:


Short-term toxicity: The results indicate that the substance is not toxic to soil macroorganisms (BASF SE, rep. no.: 99/0565/67/1, 2000)

Toxicity to birds:

Long-term or reproductive toxicity tests as well as short-term studies on birds do not need to be conducted due to the facts that a mammalian dataset is available which indicate no hazard and no bioaccumulation along the trophic chain is not expected
