Description of key information
A GLP study according to OECD Guideline 201, EU Method C.3 and EPA OTS 797.1050 is available for dipropylene glycol methyl ether and was used as a key study. A supporting study using the marine alga Skeletonema was also available.
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 1 000 mg/L
Additional information
The EC50 is greater than 1000 mg/L (nominal), as the highest concentration tested in this study induced no effect on the growth rate. The NOEC value corresponds to the highest concentration tested in this study (1000 mg/L). A second marine study using Skeletonema reported an EC50 value for growth rate of 6,999 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.
