Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Experimental studies investigating the toxicity of Fatty acids C16-18 (even numbered), oligoesters with sucrose to fish and aquatic algae are available. All studies were performed under GLP conditions and according to standard OECD guidelines. No effects were recorded in any of the available studies up to the maximum concentration/loading rate of 100 mg/L (nominal) resulting in EL/LL50 values of > 100 mg/L. The NOErLR derived from the algae study was ≥ 100 mg/L (nominal). All effect values are based on the nominal concentration/loading rate since no analytical monitoring of the test item was performed. No study investigating the toxicity of the substance to aquatic invertebrates is available. However, as the substance is poorly soluble in water (water solubility < 0.509 mg/L, OECD 105) long-term testing were considered more appropriate instead of short-term testing in accordance with Annex VII/VIII of Regulation (EC) No 1907/2006. Thus, chronic studies on aquatic invertebrates and fish were requested by ECHA in the Decision Number TPE-D-2114576748-28-01/F. The long-term toxicity study to aquatic invertebrates (OECD 211) and the Fish Early Life Stage (FELS) toxicity test (OECD 210) are planned for 2023 with final study reports expected in February and April 2024, respectively. The IUCLID dossier will be updated as soon as study reports have been reviewed and agreed.
Testing for inhibition of respiration according to OECD 209 resulted in an EC50 (3 h) > 1000 mg/L. Therefore, it is not anticipated that the test item inhibits the degradation process in sewage treatment plants.
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.
