Description of key information
With high probability acutely not harmful to algae.
Key value for chemical safety assessment

- EC10 or NOEC for freshwater algae:
- 100 mg/L
Additional information
To determine effects of DMP to algae, a study with Pseudokirchneriella subcapitata was performed according to OECD TG 201 and according to GLP. The result of the study shows an ErC50 above 100 mg/L after 72 hours and an ErC10 above 100 mg/L [BASF 2022].
This result is supported by an non-GLP algae study according to the German national standard DIN 38412 using Desmodesmus subspicatus as test species. Based on growth rate an EC50 (72 h) of approx. 259.8 mg/L [BASF, 1992] was determined.
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.
