Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Classification was done according to the criteria described in the CLP regulation EC No 1272/2008, version 2016.

Classification related key information

- Biodegradation: readily biodegradable: 100% after 28 days (OECD 301 F)

- Bioaccumulation: log Pow = 2.0 (OECD 117)

Aquatic acute toxicity

- Aquatic invertebrates: EC50 (48 h) >100 mg/L (Daphnia magna, OECD 202)

- Algae: ErC50 (72 h) = 38.1 mg/L (Pseudokirchneriella subcapitata, OECD 201)

- Fish: LC50 (96 h) >38 mg/L

The lowest L(E)C50 value was observed for algae, 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 EC50 (72 h) for algae = 38.1 mg/L, is larger than the cut-off for classification of 1 mg/L.

Aquatic chronic toxicity

- Algae: ErC10 (72 h) = 19.2 mg/L (Pseudokirchneriella subcapitata, OECD 201)

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 72 h ErC10 value for algae was 19.2 mg/L. Therefore, the substance should not be classified for chronic aquatic hazard.

Table 4.1.0 (b) (iii):

The substance is readily biodegradable, 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.
