Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The PNECs aqua were derived from the most sensitive test for the aquatic compartment,the short-term toxicity to algae. For other compartments, the PNECs are based on equilibrium partitioning.

Conclusion on classification

Short-term toxicity results for fish, Daphnia and algae are available for the substance. The 48-h EC50 value for Daphnia is 27 mg/L, the 72-h ErC50 value for algae is 7.2 mg/L,the 96 -h LC50 value for fish is >100mg/L. Since the lowest acute toxicity values is >1 mg/L, the substance does not need to be classified for acute toxicity according to EU CLP (EC no. 1272/2008, Table 4.1.0; a).

Chronic toxicity data are only available for algae. The 72-h ErC10 value is 1.8 mg/L. According to EU 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) i and 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 >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 and has a log Kow value of <4. Based on this information, the substance does not need to be classified for chronic toxicity according to Table 4.1.0, (b) iii.  

Overall, it can be concluded that the substance does not need to be classified for environmental hazards according to EU CLP EC no 1272/2008 and its amendments.
