Description of key information
No toxic effects up to the limit of water solubility (< 0.02 mg/L) for Pseudokirchnerella subcapitata (OECD 201).
Key value for chemical safety assessment
Additional information
One GLP Guideline study conducted according to OECD 201 is available investigating the toxicity of tetradecyl myristate (CAS 3234-85-3) to freshwater algae (Wenzel, 2012). The green algae Pseudokirchnerella subcapitata was exposed for 72 h to a limit Water Accommodated Fraction (WAF) concentration of nominal 100 mg/L. GC/EI-MS analysis resulted in a measured concentration of 0.142 µg/L (arithmetic mean) over the time of exposure. No effects on growth and yield of algae were observed resulting in an EL50 of > 100 mg/L (nominal) and > 1.465 µg/L (arithmetic mean of measured concentration), respectively. The NOELR was derived to be ≥ 100 mg/L (nominal) and ≥ 1.465 µg/L (arithmetic mean of measured concentration). Based on this result it can be concluded that no toxicological effects on aquatic algae are expected up to the limit of water solubility for tetradecyl myristate.
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.
