Description of key information
No effects up to the limit of water solubility (<0.05 mg/L).
Key value for chemical safety assessment
Additional information
One study on the short-term toxicity of Fatty acids, C16-18 and C18-unsatd., triesters with trimethylolpropane (CAS 68002-78-8) to aquatic algae is available (Bouillon, 2012). The study was conducted in compliance with OECD guideline 201. Pseudokirchnerella subcapitata were used as test organisms. The test solutions were prepared by using the water accommodated fraction (WAF) of the test substance. The algae were exposed to the test substance for 72 hours. Based on the growth rate of algae an EL50 > 110 mg/L (nominal) was determined.. Therefore acute toxic effects on aquatic algae are not expected within the range of the water solubility of the substance (<0.05 mg/L; Frischmann, 2012).
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.
