Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 was done according to the criteria described in the CLP regulation EC No 1272/2008, version 2016.

Acute aquatic hazard:

For classification acute toxicity data are available for fish, aquatic invertebrates (Daphnia) and algae:

Fish: LC50 (96h) = 3.00 mg/L

Daphnia: EC50 (48h) = 29.4 mg/L

Algae: EC50 (72h) = 12.3 mg/L

The lowest LC50 or EC50 value was observed for fish, which is hence the most sensitive species. According to Table 4.1.0 (a) the substance should not be classified for acute aquatic hazard, as the lowest LC50 value, LC50 (96h) for fish = 3 mg/L, is larger than the cut-off for classification of 1 mg/L.

Chronic aquatic hazard

For chronic classification, there are only chronic data available for one trophic level, algae. As described in Figure 4.1.1 in the CLP regulation (EC No 1272/2008, version 2016), the most stringent outcome of classification according to Table 4.1.0 (b) (i) or (ii) and (iii) should be used.

Table 4.1.0 (b) (ii):

The substance is readily biodegradable, hence Table 4.1.0 (b) (ii) applies.

The 72h EC10 value was found to be 7.32 mg/L (growth rate). Therefore, the substance should not be classified for chronic aquatic hazard.

Table 4.1.0 (b) (iii):

The substance is readily biodegradable and has an experimental log Kow < 4, consequently, the substance does not meet the criteria for classification for chronic aquatic hazard.

Most stringent classification:

The conclusion of both assessment is that the substance should not be classified for chronic aquatic hazard.
