Additional information

Aquatic PNECs

Data has been obtained from studies conducted with trimethylolpropane monoallyl ether (2-allyloxymethyl-2-ethylpropanediol) and the structural analogue trimethylolpropane diallyl ether ( 2,2-bis(allyloxymethyl)butan-1-ol). Data for trimethylolpropane diallyl ether (2,2-bis(allyloxymethyl)butan-1-ol) is only presented for STP toxicity as there was no STP study available for trimethylolpropane monoallyl ether (2-allyloxymethyl-2-ethylpropanediol).

The following PNECs were calculated:

PNEC Aqua (freshwater) - Based on an assessment factor of 1000, the PNEC is 0.61 mg/L.

PNEC Aqua (marine water) - Based on an assessment factor of 10000 the PNEC is 0.061 mg/L.

PNEC Aqua (intermittent releases) - Based on an assessment factor of 100 the PNEC is 6.1 mg/L.


The NOEC from the read across respiration inhibition study was 316 mg/L. Based on an assessment factor of 10 and an endpoint of 316 mg/L the PNEC STP is 31.6 mg/L.

No PNECs for other compartments (soil, air, sediment) are considered necessary.

Conclusion on classification

No classification is triggered based on available data, according to EEC Council Directive 79/831/EEC Annex VI, Part II (D) as described in Commission Directive 93/21/EEC or Regulation (EC) No 1272/2008. No hazards for the environment have been identified.
