Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
As there is no available data which establishes the toxicity of 2-allyloxymethyl-2-ethylpropanediol to STP microbes a study is read across to the structural analogue trimethylolpropane diallyl ether (2,2-bis(allyloxymethyl)butan-1-ol).
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 316 mg/L
Additional information
The toxicity of trimethylolpropane diallyl ether (structural analogue to 2-allyloxymethyl-2-ethylpropanediol) to activated sewage sludge was investigated in a respiration inhibition test according to OECD test guideline 209. Following three hours exposure to trimethylolpropane diallyl ether the EC50 was observed to be >1000 mg/L (based on nominal exposure concentrations). A 37% effect on respiration was observed at 1000 mg/L with no effect at 316 mg/L, therefore the NOEC was observed to 316 mg/L (Knight, TMPDE, 2010).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
