Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Aquatic acute toxicity

Daphnia magna, 48 h, EC50: :>0.2 mg/L (mean measured, representing the LOD; corresponding to a nominal loading rate of 100 mg/L)

Fish, 96 h, EC50 (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 plants, 7 d, EC50, NOEC (growth rate) (Lemna gibba):>0.591 mg/L (geometric mean measured; corresponding to a nominal loading rate of 100 mg/L)

Microorganisms: No data on toxicity to aquatic microorganisms were available for the registration itself. Therefore, a read across from the analogue substance Leuco Sulphur Yellow 22 (CAS 90268 -98 -7) was conducted. In an Activated Sludge, Respiration Inhibition Test according to OECD Guideline 209 the EC50 (3h) was > 1000 mg/L and the NOEC (3h) was 1000 mg/L.

Biodegradation: the substance was not readily biodegradable by OECD criteria

Log Pow: As the registration substance and the read across substance have a log Pow < 4, classification as long term (chronic) aquatic toxicity category 4 is not considered.

Classification according to CLP

The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008.

Based on the above reported results, the substance is neither classified for 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.
