EC number: 945-734-0 | CAS number: -
Short-term toxicity results for Daphnia and algae are available for the substance. The 48-h EC50 value for Daphnia is 1.456 mg/L, the 72-h ErC50 value for algae is 0.411 mg/L. Since the lowest acute toxicity value is ≤ 1 mg/L, the substance needs to be classified as Acute Cat. 1 (H400) according to EU CLP (EC no. 1272/2008 and its amendment: Table 4.1.0; a).
Chronic toxicity data are available only for algae. The 72-h ErC10/NOErC value is 0.245 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 acute value for 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 > 0.1 but ≤ 1 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 3 according to 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 > 1 but ≤ 10 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 2 according to Table 4.1.0, (b) iii.
Overall, it can be concluded that the substance needs to be classified as Acute Cat. 1 (H400) and as Chronic Cat. 2 (H411) according to EU CLP (EC 1272/2008 and its amendments).
