Conclusion on classification
Aquatic acute toxicity
48 h, EC50 (Daphnia magna): > 0.209 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) (Lemna gibba): > 0.023 mg/L (arithmetric mean measured), nominal EC50: 100 mg/L (determined for the read arcoss substance Yellow 22, CAS 90268 -98 -7)
96 h, LC50 (Danio rerio): > 0.040 mg/L (geometric mean measured), nominal: 100 mg/L based on the study with the read across substance Yellow 22, CAS 90268 -98 -7)
Aquatic chronic toxicity
7 d, NOEC (Lemna gibba): > 0.023 mg/L (arithmetric mean measured), nominal NOEC: 100 mg/L (determined for the read across substance Yellow 22 (CAS 90268 -98 -7))
No lethal or sub-lethal effects for fish, invertebrates or plants were detected up to the solubility limit of either Leucosulphur Green 16 or the read across substance Yellow 22 (CAS 90268-98-7) in the test media.
Biodegradation:
The substance was not readily biodegradable by OECD criteria (23.4 % biodegradation on day 28).
Partition coefficient:
A log Pow of < -0.1 was calculated on the
basis of the water and octanol solubility of the test item.
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 or the read across substance Yellow 22 (CAS 90268 -98 -7) no effects were shown. In combination with the low Pow the substance is not considered to be classified as hazardous for the aquatic or terrestrial environment under Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EU) No 2017/776.
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.
