Description of key information
ErC50 (72h): no effects within water solubility
NOEC (72h): no effects within water solubility
Key value for chemical safety assessment
Additional information
One study on toxicity of palmitic acid to algae is available.
The 72h test provided by the Ministry of the Environment, Government of Japan was conducted by an unknown author in 2000. It was accomplished according to OECD 201 and in accordance with GLP. Pseudokirchneriella subcapitata was tested under static conditions with 95% pure palmitic acid. The EC50 (72h) as well as the NOEC (72h) for growth rate were determined to be >0.9 mg/L.
Thus, it can be concluded that no toxic effects on aquatic algae were observed up tp the limit of water solubility.
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.
