Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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

- Cyprinus carpio: 96h-LC50: >100 mg/L

- Daphnia magna: 48h-EC50: 4.1 mg/L

- Pseudokirchneriella subcapitata: 72h-ErC50: 2.84 mg/L; 72h-ErC10: 0.32 mg/L

- Not readily biodegradable in an OECD 301B study

- Log Kow: -0.44

Acute (short-term) aquatic hazard

As the acute E(L)C50 values are >1 mg/L, the substance does not need to be classified for this hazard category according to Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP).

 

As the 48-EC50 and 72h-ErC50 are >1 but ≤10 mg/L, the substance needs to be classified for this hazard category in Category 2 according to the Globally Harmonized System of Classification and Labelling of Chemicals of the United Nations (GHS).

Chronic (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.

- CLP Table 4.1.0 (b)(i): As the 72h-ErC10 value is > 0.1 - ≤ 1 mg/L (0.32 mg/L), the substance needs to be classified based on this key result in Category 2.

- CLP Table 4.1.0 (b)(iii): As the 48h-EC50 value is >1 - ≤ 10 mg/L (4.1 mg/L) and the substance is not readily biodegradable, the substance needs to be classified based on this key result in Category 2.

It is therefore concluded that based on the currently available data, the substance needs to be classified in Category 2 for this hazard, according to CLP and according to GHS.
