Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 72h growth rate ErC50 and ErC10 values were 23 and 10 mg/L, respectively for Pseudokirchneriella subcapitata (OECD 201, static) exposed to Alcohols, C7-9-iso-, C8-rich.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 23 mg/L
- EC10 or NOEC for freshwater algae:
- 10 mg/L
Additional information
Experimental toxicity data for the registered substance are adequate for the purpose of classification and labelling and/or risk assessment. Supporting information is provided by acute and chronic aquatic toxicity values calculated using the neutral organics structure-activity relationship in the ECOSAR computer program (Nabholz and Mayo-Bean, 2009) of EPISuite; the results of which are consistent with the measured test data. Validity and applicability of the QSAR are described in a document attached as background material to the QSAR endpoint study record.
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.
