Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The information requirement on toxicity to soil macro-organisms is waived on the bases of low exposure, physical/chemical properties, and lack of toxicity observed in otehr aquatic species.
Key value for chemical safety assessment
Additional information
Tetraethylene glycol is highly water soluble (completely miscible) and has a very low potential for adsorption to organic matter. Therefore, a predicted no effect concentration (PNEC) for soil can be derived from the PNEC for freshwater using the equilibrium partitioning method. This method is applicable for substances where the toxicity in soils relates to the freely dissolved concentration in pore water. Tetraethylene glycol is not classified as dangerous for the environment and no effects have been observed in acute aquatic toxicity testing up to > 1000 mg/L and therefore no PNEC is derived. Tetraethylene glycol is readily biodegradable and has very low potential for bioaccumulation (log Kow = -2.). Hence, testing of effects on terrestrial organisms can be waived for tetraethylene glycol.
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.
