Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
EL50 (48h) = 51 mg/L for Daphnia magna
Key value for chemical safety assessment
Additional information
As there are no data available for 2-hexyldecan-1-ol ethoxylated (< 2.5 EO, CAS 52609-19-5) the acute toxicity to aquatic invertebrates is assessed on the basis of data from a study with a similar alcohol ethoxylate (iso-stearyl-ethoxylate 2EO, CAS 52292-17-8). The test was conducted according to OECD 202 and GLP, with Daphnia magna as test organism. Due to the very low water solubility of the substance, the test media were prepared as Water Accommodated Fraction (WAF). In the study an EL50 (48h) of 51 mg/L was determined (BASF, 2000).
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.
