Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Experimental studies are available for the tri and tetramethyl glycol ethers (2 -(2 -(2 -methoxyethoxy)ethoxy)ethanol and tetramethyl glycol). These studies show that the substance is effectively non toxic to fish with LC0 values above 20000mg/l. A QSAR confirms this and also shows that with increasing numbers of ethylene oxide units in the molecule, the toxicity further decreases. There is no data available on marine fish.
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.
