Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The inhibition of the degradation activity of activated sludge is not anticipated when introduced in appropriate low concentrations.
Key value for chemical safety assessment
Additional information
The toxicity of propyl acetate to microorganisms was tested in a cell growth inhibition test with Pseudomonas putida [Bringmann & Kühn, 1977]. The toxic threshold concentration, which is comparable with the EC5 was measured to be 170 mg/L after 16 h. A respiration inhibition test with activated sludge of a predominantly domestic sewage confirms the low toxicity on microorganisms [UCC, 1987]. In this test no inhibition observed up to a concentration of 1000 mg/L.
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.
