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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to fish
Administrative data
Link to relevant study record(s)
Description of key information
Measured 96hr LC50 of components: 72.9, 75.2, >10g/l respectively. Training values from QSAR of 75mg/l (DEG) and 60-77mg/l (TEG)
QSAR 96hr LC50 values of components: 38, 115, 287g/l
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 70 g/L
Additional information
There are measured LC50 values available for all of the components. However, one of these is only a limit value. The two measured values are very similar and from the structural similarity of the three components, similar toxicity would be expected. The QSAR suggests that toxicity decreases with increasingly molecular weight. All data indicates very low toxicity to fish. The key parameter is set at a rounded figure close to the two true LC50 measured values for which study reports are available. The key parameter is consistent with the QSAR and remaining limit value. The is no data for toxicity to marine water 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.
