Registration Dossier
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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Acute toxicity values:
Fish: LC50 (96hr) =70 000mg/l
Invertebrates: EC50 (48hr) =10 000mg/l
Algae: EC50 (96hr) = 6 500mg/l
Evidence from QSARs indicates that algae are the most sensitive and fish the least sensitive trophic level, confirmed by both the measured and chronic data.
Chronic toxicity values
Fish: No experimental study available, but evidence suggests that the NOEC would be higher than that for invertebrates.
Invertebrates: (Ceriodaphnia, 7 day NOEC): 8590mg/l
Microorganisms
EC10/20 (activated sludge respiration inhibition) > 1995mg/l
For the most sensitive species, algae, the critical component appears to be MEG in terms of toxicity contribution and it appears to be reasonable to use data from this component to derive conservative conclusions for the aquatic toxicity of the multi-constituent substance that is the subject of this registration dossier.
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.
