Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The following data was obtained for the Similar Substance 01. It is expected that the Target substance will present similar effect levels to microorganisms. Justification for the use of a read-across approach is provided in Section 13 of IUCLID.
The inhibitory effect of the substance to the microorganisms was assessed according to OECD guideline 209. The substance, tested in five different concentrations, was in contact with a mixed culture of a Husman apparatus. In parallel, two controls non containing the substance and a positive control, containing the reference substance run in parallel. After 3 hours, the oxygen consumption was measured in all the tested solutions, control and positive control. The log concentration-inhibition percentage was presented in a graph and the IC50 was interpolated from the graph. No inhibition was recorded up to the highest concentration tested.
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.
