Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Valid aquatic toxicity tests for fish, aquatic invertebrates and algae are available for Vinasses, residue from fermentation and are used in a read-across approach for Vinasses, residue of fermentation, depotassified.

These results clearly indicate, that Vinasses, residue from fermentation are neither acute nor chronic toxic to aquatic organisms among all trophic levels. The lowest no observed effect concentration, obtained from results of a chronic test on Daphnia magna, was used for the derivation of PNECaquatic.
Furthermore, a respiration inhibition test on activated sludge, using the same test substance resulted in an EC50(3h) > 100 mg/L, underlining the absence of harmful effects on the aquatic environment.
Since the substance is readily biodegradable, a chronic exposure in the aquatic environment is of low relevance. Together with the absence of any harmful or toxic effects on aquatic organisms, further testing on aquatic vertebrates is scientifically unjustified.
This assessment applies to Vinasses, residue of fermentation, depotassified, using the principle of read-across, as stated above. The justification of the read-across approach is provided in each subsection for specific endpoints.
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).
