Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
DPGDA is acutely harmful to aquatic algae.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 16.7 mg/L
- EC10 or NOEC for freshwater algae:
- 2.2 mg/L
Additional information
The toxicity of DPGDA on the green algae Scenedesmus subspicatus was measured in a test according to DIN 38412 [BASF AG, 1990]. The 72 -h EC50 for the growth rate determined to be between 16.7 mg/L(nominal). The 72 -h EC10 value was determined to be 2.2 mg/L (nominal). No analytical verification was performed. However, it is assumed that the test concentrations remained stable over the exposure period based on a sufficient water solubility, a low Henry's Law constant and a low adsorption potential (log Kow and log Koc < 3).
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.
