Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Conclusion on classification

The following relevant key results are currently available for deriving the classification of the substance for the environment:

- Brachydanio rerio: 96h-LC50: >102 mg/L

- Daphnia magna: 48h-EC50: 107 mg/L

- Pseudokirchneriella subcapitata: 72h-ErC50: >100 mg/L, NOEC 100 mg/L

- Not readily biodegradable

- Log Kow: 1.9

Acute (short-term) aquatic hazard

The acute LC50 or EC50 values are > 1 mg/L. The substance does not need to be classified for this hazard category according to Table 4.1.0(a) of Regulation EC1272/2008.

Long -term aquatic hazard

One chronic value is available, for algae. As there are no chronic values available for fish and crustacea, the chronic classification has to be determined with the available chronic data for algae based on CLP Table 4.1.0 (b)(i), as the substance is not readily biodegradable, and with the available acute data for fish and Daphnia magna based on CLP Table 4.1.0 (b) (iii). The most stringent classification is valid. As no effects were observed in the algae and fish studies, only the 48h-EC50 for Daphnia magna is relevant;

CLP Table 4.1.0 (b)(iii): As the EC50 value for Daphnia is >100 mg/L, the substance does not need to be classified based on this key result.

In conclusion, the substance is not classified (for acute or chronic hazards).
