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

No analytical monitoring was done in tests on fish and daphnia. However, no evidence of precipitation was reported.

Analytical monitoring was carried out only in the test on lemna. OECD medium was used instead of 20AAXP medium, as test item precipitated from the 20AAXP medium in 24 hours, even upon filtration. As test substance was not stable for 3 days in OECD medium, the test was run as semistatic, with renewals on day 3 and 5. Final results were derived from measured concentrations. Results were only based on frond numbers as dry weigth could not be assessed due to the substance deposition on roots and/or leaves of plants.
