Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aquatic invertebrates: EC0 (48h) = 78 mg/l, EC50 (48) > 78 mg/l
Aquatic plants: EC50 (7d) = in progress
Additional information
As no data on target substance was available, aquatic toxicity was assessed relying on data on Similar Substance 01 and 03. Details on the read across approach are attached in section 13.
Both target and read across substances are expected to be devoid of a potential for ready biodegradability and bioaccumulation.
Aquatic invertebrates
Acute toxicity of Similar Substance 01 to daphnia magna was assessed in a 48 -hour study according to OECD 202. Effect levels in terms of immobilisation were determined as measured concentrations:
EC0 (48h) = 78 mg/l
EC50 (48h) > 78 mg/l
Algae
Due to its specific nature, this type of test was considered as not adequate to assess the potential toxicity of test substance, due to the influence of colouration of test substance on test outcome. Therefore, this study was not conducted.
Aquatic plants other than algae
In progress.
Justification for classification or non-classification
According to the CLP Regulation (EC 1272/2008), the threshold of classification of a substance for acute aquatic toxicity is 1 mg/l. This limit is compared with EC50 (48 h) for crustacea and EC50 (72 - 96 h) or EC50 (7d) for aquatic plants. Moreover, in case of lack of chronic data, the potential for chronic toxicity is identified by appropriate combinations of acute toxicity data and lack of biodegradability. The threshold of classification for chronic toxicity is 100 mg/l.
Based on available data, low aquatic toxicity was assumed, however such conclusion will be confirmed once new data on aquatic plants is available.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
