Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

An assessment factor 100, 1000, 10 was used for PNEC aqua (freshwater), PNEC aqua (marine water) and PNEC aqua (intermittent releases), respectively, based on the lowest L(E)C50 of three short-term tests from three trophic levels. The short-term tests were conducted according to EU guidance, and GLP fulfilled. An estimated ErC50 on algae was also made by QSAR (all the conditions in REACH Annex XI 1.3 are met), which indicated that algae was the most sensitive species, the same with that derived from testing data. So the most conservative assessment factor was not used.

Conclusion on classification

Does not meet criteria for classification as, though the LD50 for algal growth inhibition is low enough for classification for chronic aquatic toxicity category 3, the substance is readily biodegradable and has low potential for bioaccumulation so does not meet the criteria.
