Conclusion on classification
Aquatic acute toxicity
96 h, LC50 (Danio rerio): >
0.32 mg/L (equivalent to > 100 mg/L nominal concentration),
based on results obtained in a preliminary study with the read across
substance Blue Sema, CAS 1040873 -93 -5
48 h, EC50 (Daphnia magna): > 0.45 mg/L (geometric mean measured;
solubility limit of the test item in the test medium, corresponding to a
nominal loading rate of 100 mg/L)
7 d, EC50 (growth rate based on frond number and dry weight) (Lemna
gibba): >0.305 mg/L (time-weighted mean measured concentration;
solubility limit in the test medium; nominal 25 mg/L)
Aquatic chronic toxicity
7 d, NOEC (growth rate based on frond number and dry weight) (Lemna
gibba): 0.305 mg/L (time-weighted mean measured concentrations;
solubility limit in the test medium; nominal 25 mg/L)
Biodegradation:
The substance was not readily biodegradable by OECD criteria (9.9 %
biodegradation on day 28).
Partition coefficient:
Log Pow < -0.3 at 20 °C.
No lethal or sub-lethal effects for invertebrates and no significant
inhibition of growth rate and yield of Lemna gibba were detected up to
the solubility limit of the test item in the test media.
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for
classification purposes under Regulation (EC) No 1272/2008. Up to the
solubility limit of the test item no effects were shown. In combination
with the low Pow, the substance is not considered to be classified as
hazardous for aquatic toxicity under Regulation (EC) No 1272/2008,as
amended for the twelfth time in Regulation (EU) 2019/521.
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.
