Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
ErC50 (72 h) > 51 mg/L (highest concentration tested) for Pseudokirchneriella subcapitata (OECD 201)
NOErC (72 h) >= 51 mg/L (highest concentration tested) for Pseudokirchneriella subcapitata (OECD 201)
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 51 mg/L
- EC10 or NOEC for freshwater algae:
- 51 mg/L
Additional information
One study investigating the toxicity of D-Glucopyranose, oligomeric, butyl glycoside to freshwater green algae is available. In this key study performed according to OECD 201 and GLP, Pseudokirchneriella subcapitata was exposed to nominal concentrations of 1, 10, and 100 mg/L of a 51% solution in a static test design. Analytical verificaton of the highest test substance concentration was achieved by TOC measurement and resulted in 87.3 to 98.9 % recovery of TOC. No effects were observed in any treatment, therefore an ErC50 (72 h) value of > 100 mg/L was reported, equivalent to > 51 mg a.i./L, the highest concentration tested (Institut Technologique FCBA, 2010).
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.
