Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity results for fish, Daphnia and algae are available for the substance. The 96-h LC50 value for fish is 11 mg/L, the 48-h EC50 value for Daphnia is 14.1 mg/L, and the 72-h ErC50 value for algae is 3.72 mg/L. Since the acute toxicity values are >1 mg/L, the substance does not need to be classified for acute toxicity according to EU CLP EC No. 1272/2008 and its updates, Table 4.1.0; a).

Chronic toxicity data are available only for algae. The 72-h ErC10 value is 1.19 mg/L. According to CLP Figure 4.1.1, the chronic classification has to be determined based on the chronic value for algae according to Table 4.1.0, (b) ii, as well as the lowest acute value of the other trophic level available thus for fish and Daphnia according to Table 4.1.0, (b) iii, and the most stringent outcome should be leading:

- The substance is readily biodegradable and has a chronic toxicity value of >1 mg/L. Based on this information, the substance does not need to be classified for chronic toxicity according to Table 4.1.0, (b) ii.

- The substance is readily biodegradable, has a log Kow value of >4 and an acute toxicity value of >10 but ≤100 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 3 according to Table 4.1.0, (b) iii.

Overall, it can be concluded that the substance needs to be classified as Chronic Cat. 3 (H412) according to EU CLP (EC No. 1272/2008 and its updates).

GHS: The lowest acute toxicity of other than algae is >10 but ≤100 mg/L, which resuls in the classification of Acute Cat. 3 (H402).
