Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Classification based on biodegradation, bioaccumulation and acute aquatic data

 

Biodegradation: not readily biodegradable (EPISuite estimation)

LogPow: 3.18, 3.39 and 3.19, respectively at pH 5, 7 and 9 (EU method A.8) / 2.45 (US EPA PAG 63-11)

 

Aquatic acute toxicity

For fish: LC50(96 h) = 18 mg/L, (OECD 203, rainbow trout)

For aquatic invertebrates: EC50(48h) = 2 mg/L (OECD II A 8.3.1, Daphnia Magna)

For algae: ErC50(72 h) > 16 mg/L, (OECD 201, Pseudokirchnerella subcapitata)

 

Based on the data above, the substance is considered to be not rapidly degradable and indicates a rather low potential for bioaccumulation.

 

Classification and labelling according to Regulation (EC) No.1272/2008 (CLP):

The criteria for classification of a substance in category Acute 1 are defined on the basis of acute aquatic toxicity data only (EC50 or LC50); classification is required for values ≤ 1 mg/L. Therefore, the substance does not need to be classified for acute (short-term) aquatic hazard.

 

No chronic data as required (NOAEC) by Regulation 1272/2008 are available and hence, the result from the short-term tests have to be assessed according to the respective criteria for chronic aquatic hazard in combination with the biodegradation and bioaccumulatoin (log Pow as BCF is not available) data. In the absence of chronic data the chronic classification for Category 2 is based on acute aquatic toxicity data > 1 to ≤ 10 mg/L for daphnia (2 mg/L) and the fact that the substance is not rapidly degradable although the substance indicate a low potential of bioaccumulation.
