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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
It should be noted that a loading rate of 100 mg/L did not cause any toxicity in fish, aquatic invertebrates and algae. This is probably due to the very low solubility of FAT 41043/A TE in water, which means that concentration levels that might be toxic could not be reached.
Conclusion on classification
A loading rate of 100 mg/L did not cause any toxicity in fish, aquatic invertebrates and algae. This is probably due to the very low solubility of FAT 41043/A TE in water, which means that concentration levels that might be toxic could not be reached. The NOEC algae of 21 ng/L(TWA), being a chronic toxicity endpoint, is assumed to be > the water solubility; this results in no need for environmental classification.
Under the DSD Regulation, the substance should be classified as R53 as the NOEC algae, being the only chronic toxicity endpoint, cannot be used as additional scientific evidence for waiving environmental classification.
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.
