Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Studies on the acute toxicity of the substance are available for fish and algae. The acute toxicity data for aquatic invertebrates refer to results obtained for glyoxal a stuctural analogue of pyruvaldehyde.
The most sensitive organism in acute toxicity testing was Daphnia magna with an EC50 of 404 mg/l based on the nominal test substance concentration. In a test on Scenedesmus subspicatus an EC50 of 731.5 mg/l was the recorded. The LC50 determined in a study on Leuciscus idus was ca. 1000 mg/l.
The PNEC calculations are based on the results of the acute toxicity test performed with D. magna. The equilibrium partitioning method was used for calculating the PNECsediment freshwater/marine and the PNECsoil.
The PNEC STP was calculated using the EC10 of 6.7 mg/l determined in a growth inhibition test with the bacteria species Pseudomonas putida.
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.
