Description of key information
Waiving of Study:
In accordance with column 2 of REACH Annex IX, the test on long-term toxicity to fish (required in section 9.1.6) does not need to be conducted as the chemical safety assessment according to Annex I indicates no need to investigate further the effects on aquatic organisms. The following aspects need to be considered: In general, the results obtained for the effect and no-effect concentrations based on the acute aquatic toxicity studies are low but significantly higher than for the most sensitive species (Algae) also triggering the PNEC. However, the log Pow of 1.94 does not indicate a potential for bioaccumulation, the water solubility of Olaflur was determined to be 164 g/L and thus very good. In addition, the calculated BCF by EPIWIN (BCFBAF v.3.00) revealed a figure of 8.851 L/kg, also supporting the conclusion that Olaflur will not bioaccumulate. Furthermore, the substance can be classified as ready biodegradable. Taking these findings together, a long-term exposure of aquatic organisms to ecotoxicological relevant concentrations of Olaflur can be excluded. Hence, further information concerning long-term effects on aquatic organisms is dispensable.

Additional information
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.
