Description of key information
LC50 (96h) = 8.15 mg/L for Pimephales promelas (OECD 203), read across
Key value for chemical safety assessment
Additional information
Since no studies investigating the acute toxicity to fish of alcohols, C16-18, ethoxylated, phosphates (CAS 106233-09-4) are available, in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5 read across to the structurally similar substance alcohol ethoxylate (C16-17, branched and linear, 2 EO ) was conducted. This read-across is justified in detail in the overall summary (IUCLID chapter 6.1) and within the analogue justification in IUCLID Section 13.
The study investigated the effect on feathead minnow (Pimephales promelas) under static conditions according to OECD guideline 203 without GLP compliance (Hartwell, 2011). An LC50 (96h) of 8.15 mg/L based on nominal concentrations is reported.
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.
