Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 study was conducted in compliance with GLP and equivalent to OECD Guideline 211 (Daphnia magna Reproduction Test), however only two test concentrations were tested.
Key value for chemical safety assessment
Additional information
The NOEC is 0.5 mg/L, as no effects were observed at the two test concentrations 0.5 and 0.05 mg/L. The concentrations tested in this study were set very low, despite the observed low acute toxicity (EC50>1000 mg/L) of dipropylene glycol methyl ether.
The NOEC is defined as the test concentration immediately below the LOEC which, when compared to the control, has no statistically significant effect (p<0.05) within a given exposure time. Because a LOEC could not be identified, it can be designated as >0.5 mg/L making the NOEC >= 0.5 mg/L.
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.
