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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
Based on experimental studies on the registered substance, the key ecotoxicity values of the substance are as follow:
- Aquatic Invertebrates: 48-h EL50 was 135 mg test material/L
- Aquatic algae: 72-h ErL50 was 349 mg test material/L
Based on these results,acute E(L)C50s are higher than 1 mg/L.
Therefore, the substance would not be classified as acute 1 to aquatic organismsin accordance with the classification of the CLP.
Additional information
The registered substance is a Natural Complex Substance (UVCB).
Acute toxicity of the registered substance to aquatic invertebrates (Daphnia magna) and to freshwater algae have been determined in experimental studies using WAFs and performed under GLP compliancein accordance with OECD 202 and 201 guidelines respectively.
The respective validity criteria were fulfilled and both studies complied with the requirements of the test guidelines. These studies were therefore considered acceptable for the two endpoints.
In the dataset, short-term toxicity to fish was not provided since the tonnage band (1 -10 tonnes/year) does not require that endpoint.
CLP Classification proposal
It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation (including 2nd Adaptation to Technical Progress, Com Reg No 286/2011).
Acute aquatic hazard: Not classified. Reasoning: lowest E(L)C50 higher than 1 mg/L.
Chronic aquatic hazard: Not Classified Reasoning: Adequate chronic toxicity data are not available and the lowest acute E(L)C50 is comprised between 100 and 1000 mg/L.
The substance is not readily biodegradable, with some constituents having estimated log Kow > 4, and effects to aquatic organisms were observed for the highest tested loading rates.
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.
