Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a guideline (OECD 203) GLP study modified to marine conditions, the 96 -hour LC50 of a commercial substance that meets the description "Poly(oxy-1,2,-ethanediyl), α-butyl, ω-hydroxyl" to Turbot was determined to be >1800 mg/L. Based on the information available, this substance would be not be classified toxic to the environment according to the classification system of the EU.
It should be noted that the ECOSAR predicts a decrease in toxicity with increasing number of ethylene oxide units. The QSAR predicts that 2-(2-(2-(2-butoxyethoxy)ethoxy)ethoxy)ethanol will have an LC50 twice as high as 2-(2-(2-butoxyethoxy)ethoxy)ethanol.
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.
