Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
Toxicity to algae: NOEC (72h, growth rate & yield) ≥ 100 mg/L, LOEC, EC10, EC50 (72h, growth rate & yield) > 100 mg/L for Desmodesmus subspicatus (OECD 201, EU method C.3, static)
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 100 mg/L
Additional information
There is a Klimisch 1 (OECD 201 on Desmodesmus subspicatus over 72h) available. In this study, the highest concentration tested was 100 mg/L, and the results are: NOEC (72h, growth rate & yield) ≥ 100 mg/L, LOEC, EC10, EC50 (72h, growth rate & yield) > 100 mg/L. Based on this data, there is no classification as hazardous to the aquatic environment, neither acute nor chronic, according to Regulation (EC) No 1272/2008 and amendments, triggered. There is no indication given that this data is not relevant for the assessment of ecotoxicological properties of SPS. The conclusion that SPS is relatively harmless to aquatic organisms is supported by related data on P. putida (NOEC (16h) ≥10000 mg/L). Hence, no data gap was identified, and the key value, NOEC (72h, growth rate & yield) ≥ 100 mg/L, can be chosen for further risk assessment.
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.
