Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 and daphnids are available for the substance. The 96 -h LC50 in fish is 0.17 mg/L, 48-h EC50 value for Daphnia is 0.18 mg/L. Since the acute toxicity values are ≤ 1 mg/L, the substance needs to be classified as Acute Cat. 1 (H400) according to Regulation 1272/2008/EC (CLP; Table 4.1.0; a).

Chronic toxicity data is available only for algae. The 72-h NOEC value is 0.17 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 available 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 > 0.1 but ≤ 1 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 3 (H412) according to according to Table 4.1.0, (b) ii.

- The substance is readily biodegradable, has a log Kow value of ≥4 and a lowest acute toxicity value of ≤ 1 mg/L. Based on this information, the substance needs to be classified as Chronic Cat. 1 (H410) according to Table 4.1.0, (b) iii.

Overall, it can be concluded that the substance needs needs to be classified as Acute Cat. 1 (H400) and as Chronic Cat. 1 (H410) according to Regulation 1272/2008/EC (CLP, 2014). The M-factor is 1 for both acute and chronic toxicity.
