Key value for chemical safety assessment
Additional information
One experimental study investigating the short-term toxicity to marine invertebrates of Fatty acids, C16-18, tetraesters with 3,3'-oxybis[1,2-propanediol] (CAS 91050-80-5) is available (Hudson, 2007). This study with Fatty acids, C16-18, tetraesters with 3,3'-oxybis[1,2-propanediol] was performed according to ISO 14669 under GLP conditions. Acartia tonsa was exposed to five nominal concentration between 1000 and 10000 mg/L, which were prepared as Water Accommodated Fraction (WAF), in a static test for 48 h. Immobilisation/ mortality was observed at the two highest test concentrations resulting in an EL50 (48 h) = 7460.29 mg/L (nominal). Although the test solutions were prepared as Water Accommodated Fractions (WAF), floating or settled particles were observed at the lowest test concentration of 1000 mg/L after 3 hours stirring. Therefore, the mortality at the two highest test concentrations are probably caused by physical effects due to undissolved test material. It is thus not expected that the reported EL50 refers to a systemic toxic effect. Thus, it can be concluded that Fatty acids, C16-18, tetraesters with 3,3'-oxybis[1,2-propanediol] show no effects up to a loading rate of 1000 mg/L (nominal).
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.
