Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PNECs were derived based on test data following standard guidelines. All data are considered to be reliable and relevant for the endpoint concerned.

 

Short-term aquatic data in freshwater are available for three trophic levels for the test item. The most sensitive endpoint was determined to be algae, with a 72-hour EC50 of 11.4 mg/L (2015). This endpoint was used to derive the PNECs for freshwater, marine water and intermittent releases by assessment factor method, and freshwater sediment, marine sediment and soil by equilibrium partitioning approach.

 

For derivation of the PNEC for STP, the NOEC of 20 mg/L was taken from the toxicity control of a ready biodegradability test (2015). A PNEC of 2 mg/L is derived by applying an assessment factor of 10.

 

The test item has low vapour pressure (3.7, 5.4 and 29.7 Pa at 20, 25 and 50°C, respectively (2014)), therefore it is not a precursor to ozone formation and is not expected to be a significant contribution to global warming. The test item is not an ozone depleting substance as defined by the Montreal Protocol and does not contain chemical constituents that would lead to acidification.

 

No hazard is expected from secondary poisoning. The measured log Kow value of 3.55 indicates that the test item is not potentially bioaccumulative. Since the test item has no bioaccumulation potential, a secondary poisoning assessment is not required.

Conclusion on classification

Acute aquatic data are available for three trophic levels for the test item. No chronic toxicity data are available for the test substance. The most sensitive endpoint was determined to be algae, with a 72 -hour ErC50 of 11.4 mg/L (2015). The test item achieved biodegradation of 15.5 and 22 % after 28 days and, therefore, is considered to be not readily biodegradable. Since the 72 -h ErC50 from algae study is > 10 to ≤ 100 mg/L, and the substance is not readily biodegradable, the test item is classified as hazardous to aquatic environment with a Chronic Category 3.
