Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Main study:

50% lethal concentration

24-hour 50% lethal concentration (LC50): 2.9 mg/L (95% confidence limit: 2.3-3.8 mg/L),

48-hour 50% lethal concentration (LC50): 2.7 mg/L (95% confidence limit: 2.3-4.7 mg/L),

72-hour 50% lethal concentration (LC50): 2.7 mg/L (95% confidence limit: 2.0-4.0 mg/L),

96-hour 50% lethal concentration (LC50): 2.5 mg/L (95% confidence limit: 1.9-3.7 mg/L)

 

Non-GLP Supporting study:

 

96h LC50 >1.0 mg/l, <10 mg/l.

 

Daphnia:

 

Acute

 

Result after 24 hours

50% effective inhibitory concentration (EC50): > 10 mg/L. The highest concentration causing 0% immobility: 2.1 mg/L. The lowest concentration producing 100 % immobility: > 10 mg/L

 

Result after 48 hours

50% effective inhibitory concentration (EC50): 2.9 mg/L (95% confidence limit: 2.5-3.4 mg/L). The highest concentration causing 0% immobility: 1.5 mg/L. The lowest concentration producing 100 % immobility: 10 mg/L

 

Chronic:

 

The results for this study are taken from the SIDS Initial Assessment Report, For SIAM 4, Tokyo, Japan, 20-22 May 1996, as the full report was not able to be located. The results are considered reliable as a data source used to support the SIDs programme; results collaborate with acute results that could be located. The full report is available at http://www.inchem.org/documents/sids/sids/1879090.pdf. As the lowest chronic toxicity result, the 21 d-NOEC (reproduction) of Daphnia magna (0.32 mg/l) was adopted for the purposes of risk assessment.

Algae:

50% growth inhibition concentration ErC50 (0-48): 5.4 mg/L (95% confidence limit: 5.0-5.9 mg/L)

 

Maximum no effect concentration NOEC (Rate 0-48): 0.40 mg/L

 

50% growth inhibition concentration ErC50 (0-72): 6.0 mg/L (95% confidence limit: 5.3-6.6 mg/L)

 

Maximum no effect concentration NOEC (Rate 0-72): 0.38 mg/L

 

Micro-organisms:

 

EC50 (3 hour contact time) >10 mg/l.

 

Conclusion on classification

On the basis of the results noted in the studies, classification under the CLP Regulation (EC No 1272/2008 is as follows:


Chronic aquatic toxicity, Category 2; H411: Toxic to aquatic life with long lasting effects.
