Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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) = 708.7


RHO_(susp) = 1150


Conversion factor (wwt -> dwt): 4.6


PNEC_freshwater sediment


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


= (708.7/1150) * 0.015 * 1000


= 9.244 mg/kg wwt


= 42.522 mg/kg dw


 


PNEC marine water sediment:


K_(susp-water) = 708.7


RHO_(susp) = 1150


Conversion factor (wwt -> dwt): 4.6


PNEC_marine water sediment


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


= (708.7/1150) * 0.0015 * 1000


= 0.924 mg/kg wwt


= 4.252 mg/kg dw


 


PNEC soil:


K_(soil-water) = 850.2


RHO_(soil) = 1700


Conversion factor (wwt -> dwt): 1.13


PNEC_soil


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


= (850.2/1700) * 0.015 * 1000


= 7.502 mg/kg wwt


= 8.477 mg/kg dw

Conclusion on classification

Aquatic acute toxicity


96 h, LC50 (Danio rerio): 27.79 mg/L (nominal concentration)


48 h, EC50 (Daphnia magna): 68.79 mg/L (nominal concentration)


72 h, ErC50 (Pseudokirchneriella subcapitata): 14.80 mg/L (geometric mean measured concentration)


 Aquatic chronic toxicity


72 h, NOEC (Pseudokirchneriella subcapitata): 6.13 mg/L (geometric mean measured concentration)


 Biodegradation: not biodegradable: 5.9 % after 28 days (% degradation O2 consumption, OECD 301 D)


Partition coefficient: log Kow = 5.13 at 25 °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 not biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the toxicity test to algae. This study revealed a 72h- EC50 of 14.80 mg/L and the 72h-EC10 was determined to be 6.13 mg/L. Based on these results, the substance is not classified as short term (acute) aquatic toxicity and is classified as long term (chronic) aquatic toxicity in Cat. 3 (H412) according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Commission Regulation (EU) 2020/1182.
