Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PNEC sediment(freshwater), PNEC sediment (marine waters), PNEC soil

No toxicity tests with sediment dwelling or terrestrial organisms are available. Thus, in accordance with the Guidance on information requirements and chemical safety assessment, Chapter R.10: Characterisation of dose [concentration]-response for environment, 2017, the PNEC for freshwater and marine water sediment as well as the PNEC soil have been calculated with the equilibrium partitioning method using EUSES 2.1.

 

The following data have been taken into account for calculation: 

Molecular weight

350.39 g/mol

Melting point

79.8°C

Boiling point

275°C

Vapour pressure

 

Water solubility

938000 mg/L at 20°C

Log Kow

-0.64

PNEC Aqua(freshwater)

1.8 µg/L

PNEC Aqua(marine water)

0.18 µg/L

 

The calculation resulted in a PNEC sediment(freshwater) of 7.36 µg/kg sediment dw, a PNEC sediment (marine waters) of 0.736 µg/kg sediment dw and a PNEC soil of 0.415 µg/kg soil dw.

Conclusion on classification

The most sensitive organism to ETPPAAc was Daphnia magna (EC50 = 1.8 mg/L).

In accordance with Regulation EC No 1272/2008, based on these results and the substance being not rapidly biodegradable, ETPPAAc has to be classified as Aquatic Chronic 2.
