Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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


 


PNEC freshwater sediment:


K_(susp-water) = 2800


RHO_(susp) = 1150


Conversion factor (wwt -> dwt): 4.6


PNEC_freshwater sediment


= (K_(susp-water) / RHO_(susp)) * PNEC_water * 1000


= (2800/1150) * 0.186 * 1000


= 452.87 mg/kg wwt


= 2083.20 mg/kg dw


 


PNEC marine water sediment:


K_(susp-water) = 2800


RHO_(susp) = 1150


Conversion factor (wwt -> dwt): 4.6


PNEC_marine water sediment


= (K_(susp-water) / RHO_(susp)) * PNEC_marine water * 1000


= (2800/1150) * 0.0186 * 1000


= 45.287 mg/kg wwt


= 208.320 mg/kg dw


 


PNEC soil:


K_(soil-water) = 3360


RHO_(soil) = 1700


Conversion factor (wwt -> dwt): 1.13


PNEC_soil


= (K_(soil-water) / RHO_(soil)) * PNEC_freshwater * 1000


= (3360/1700) * 0.186 * 1000


= 367.624 mg/kg wwt


= 415.415 mg/kg dw

Conclusion on classification

Acute aquatic toxicity:

96 h, LC50 (Oncorhynchus mykiss): >100 mg/L (nominal concentration)

48 h, EC50 (Daphnia magna): >100 mg/L (nominal concentration)

72 h, ErC50 (Pseudokirchneriella subcapitata): >100 mg/L (nominal concentration)

Aquatic chronic toxicity:

72 h, ErC10 (Pseudokirchneriella subcapitata): >100 mg/L (nominal concentration)

Biodegradation: inherently biodegradable: 37 % after 28 days (% degradation CO2 evolution, OECD 310) and 86 % 28 after days (% degradation O2 consumption, OECD 302C)

Partition coefficient: log Kow = 2.66 at 20 °C

Classification according to CLP

The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to be primarily inherently biodegradable under the test conditions. In all aquatic tests the test item showed no toxic effect on the tested species up to the water solubility of the test item. The determined EC50 and EC10 for Daphnia magna and green algae were >100 mg/L (nominal). The LC50 to rainbow trout was determined to be >100 mg/L (nominal). Based on these results, the substance is neither classified for short-term (acute) aquatic toxicity nor classified for long-term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the twelfth time in Regulation (EU) 2019/521.
