Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The chemical safety assessment carried out according to Annex I of Regulation (EC) No 1907/2006 does not indicate the need to investigate further the long-term toxicity to fish.
Key value for chemical safety assessment
Additional information
There are no long-term fish studies available for tetradecyl myristate (CAS 3234-85-3). Available short-term toxicity studies for fish, daphnia and algae, all indicate no potential for aquatic toxicity. Moreover a NOEC obtained from an algal growth study is clearly above the limit of water solubility.
For the LCAE category member fatty acids, C8 - 10, C12 - 18-alkyl esters (CAS 95912-86-0) a long-term study according to OECD 211 is still ongoing. But it is not expected that the results from the new study will lie out of the overall ecotoxicological profile of the category. Nevertheless, the Chemical Safety Assessment according to Annex I of Regulation (EC) No 1907/2006 will be re-evaluated based on the outcome of the new studies as soon as they are available.
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 then the ongoing long-term test with aquatic invertebrates. Due to its ready biodegradability it is not likely that aquatic organisms are exposed to the test substance since it will be ultimately degraded in sewage treatment plants. Thus, based on the above mentioned results, it can be excluded that any substance within the category 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. Thus, the chemical safety assessment carried out according to Annex I of Regulation (EC) No 1907/2006 does not indicate the need to investigate further the long-term toxicity to fish. Thus, in accordance to Annex IX, column 2 no further long-term toxicity test to fish is 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.
