Description of key information
Following the final decision CCH-D-2114449810-49-01/F the registrant added the following information.
EC50 and EC10 were recalculated with Toxrat® 3.2.0 to respectively 196 and 118 mg/L respectively.
EDIPA was found to be slightly harmful to algae.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 196 mg/L
- EC10 or NOEC for freshwater algae:
- 118 mg/L
Additional information
The determination of the growth inhibition of the freshwater algae Pseudokirchneriella subcapitata exposed to Ethyldiisopropylamine for a duration of 72h was performed according to the OECD guideline 201. As indicated in the OECD 201 guideline, the pH of the stock solution was adjusted to 8 in order to limit the pH increase during the test. The validity criterion of the study related to the growth of algae was respected and the final concentrations were maintained within the designated limit of 80% of the initial concentrations in non inoculated flasks. Following the final decision CCH-D-2114449810-49-01/F the registrant added the additional information. EC50 and EC10 were recalculated with Toxrat® 3.2.0 to respectively 196 and 118 mg/L respectively.
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.
