Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 ECOSAR model v.1.11 (EPISuite v.4.10) estimated the 96 hour EC50 value to be 73.149 mg/L.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 73.149 mg/L
Additional information
The toxicity potential of the test material to green algae was estimated using a validated QSAR model.
The structure-activity relationships (SARs) presented in this program are used to predict the aquatic toxicity of chemicals based on their similarity of structure to chemicals for which the aquatic toxicity has been previously measured. Most SAR calculations in the ECOSAR Class Program are based upon the octanol/water partition coefficient (Kow). Various surfactant SAR calculations are based upon the average length of carbon chains or the number of ethoxylate units.
The ECOSAR model v.1.11 (EPISuite v.4.10) estimated the 96 hour EC50 value to green algae to be 73.149 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.
