Additional information
There are no long-term fish studies available for Fatty acids, C8-10, C8-10 alkyl esters (CAS 129677-93-6). Available short-term studies for fish, aquatic invertebrates and algae, all indicate no potential for aquatic toxicity. Moreover, NOEC values obtained from algal growth studies and daphnia reproduction studies are clearly above the limit of water solubility. As there was no sign that invertebrates are less sensitive than fish in the short-term tests, it cannot be expected that a long-term test with fish will generate different results than the existing long-term tests with aquatic invertebrates. Due to its ready biodegradability it is not likely that aquatic organisms will be exposed to the target substance. They will be ultimately degraded in sewage treatment plants. Thus, based on the above mentioned results, it can be excluded that the target substance will exhibit chronic toxicity to fish up to the limit of water solubility. Hence due to animal welfare reasons and to avoid unnecessary vertebrate tests, no further long-term test with fish was proposed.
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.
