Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Official classification:

Aquatic compartment

In accordance with Regulation (EC) No 1272/2008, Annex VI Table 3.1, the substance is not officially classified.

In accordance with Regulation (EC) No 1272/2008, Annex VI Table 3.2, the substance is not officially classified.

 

Self-classification:

Aquatic compartment

Following CLP, the substance is not to be classified as acutely hazardous to the aquatic environment. Based on the available acute and chronic data, the substance is not to be classified as chronically hazardous to the aquatic environment.

 

Rationale:

The substance is not classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is >> 1 mg/L (limit test; worst-case approach; nominal, analytically verified, Lonza Ltd: rep. no.698 -201 -0756 (daphnia, 2015) and 698 -201 -0756 (algae, 2017)).

Chronic data are available only for algae, therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data:

Chronic toxicity data are available for algae (72 -h ErC10 = 100 mg/L, Lonza Ltd, 2017). According to the criteria outlined in Table 4.1.0(b)(i) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008 for non-rapidly degradable substances for which adequate chronic toxicity data are not available) the substance is not to be classified as chronically hazardous to the aquatic environment.

- Acute toxicity data:

According to the available short-term toxicity data for fish and aquatic invertebrates no toxicity observed up to the highest tested concentration of 100 mg/L.  Therefore, the classification is based on the acute E(L)C50 value of 100 mg/L. The substance is not readily biodegradable (see IUCLID Ch. 5.2.1), the log Kow < 4 (log Kow = -0.49, Lonza Ltd, 2015) and the estimated BCF < 500 (max. BCF = 3.2 L/kg, see IUCLID Ch. 5.3.1). According to the criteria outlined in Table 4.1.0 (b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272 (2008) the substance is not to be classified as chronically hazardous to the aquatic environment.

 

- Conclusion:

Based on the available acute and chronic toxicity data, the substance is not chronically hazardous to the aquatic environment.
