Description of key information
No toxic effects occur at the range of solubility.
Key value for chemical safety assessment
Additional information
In a 72h non-GLP guideline study using Scenedesmus subspicatusas as test organism, an EC50 of 33.9 mg/L for biomass was determined (CIBA-GEIGY 1992, Report 928144). DMF and Alkyl-phenol-polyglycolether were used as a vehicle. No effects in the solvent control could be observed.
In a 72h non-GLP guideline study on an analogues substance using Scenedesmus subspicatus as test organism, an EC50 of 60 mg/L for biomass was determined. Lecithin was used as a solvent, however in a very high concentration 0.4 mg/L, which is above the vehicle limit of present guidelines. Almost 30 % of algae were inhibited in the solvent control (CIBA-GEIGY 1992, Report 928155).
In conclusion, both effect concentrations are well above the solubility limit of the test substances (water solubility < 1 mg/L, see chapter 4.8 in IUCLID). Therefore, they represent a worst case assumption where water solubility is achieved by excessive use of solvent. In conclusion, the substance shows no effect in the range of water solubility.
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.
