Conclusion on classification

Aquatic acute toxicity

48 h, EC50 (Daphnia magna): > 1.27 mg/L (reflecting aquatic saturation, based on a nominal loading rate of 100 mg/L)

7 d, EC50 (growth rate) (Lemna gibba): > 0.4 mg/L (reflecting aquatic saturation, based on a nominal loading rate of 100 mg/L)

96 h, LC50 (Danio rerio): > 0.32 mg/L (reflecting aquatic saturation, based on a nominal loading rate of 100 mg/L) (read across from source substance Leuo Sulphur Blue Sema, CAS 1040873 -93 -5)

 

Aquatic chronic toxicity

7 d, EC10 (growth rate) (Lemna gibba): > 0.4 mg/L (reflecting aquatic saturation, based on a nominal loading rate of 100 mg/L)

No lethal or sub-lethal effects for fish, invertebrates or plants were detected up to the solubility limit of the registration substance in the test media.

 

Biodegradation:

The substance was not readily biodegradable by OECD criteria (9.3 % biodegradation on day 28).

Partition coefficient:

Log Pow < -0.1 at 20 °C.

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. The test substance was found to be not readily biodegradable under the test conditions. In studies with Lemna gibba and Daphnia magna the LOEC was determined to be higher than the solubility level of the substance (>0.4 mg/ and 1.27 mg/L, respectively; nominal loading rate of 100 mg/L in both studies). The LC50 for Danio rerio was >0.32 mg/L representing the limit of solubility in the medium (nominal loading rate of 100 mg/L) based on a study with the read across substance Blue Sema (CAS No 1040873 -93 -5). As the registration substance has a log Pow < 4 (< -0.1 at 20 °C), classification as long term (chronic) aquatic toxicity category 4 is not considered. Based on these results, the substance is neither classified as short term (acute) aquatic toxicity nor classified for long term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP) as amended for the twelfth time in Regulation (EU) No 2019/521.
