Description of key information
Isopropenyl acetate was administered to inoculum (activated sludge of a predominantly domestic sewage plant) according to OECD Guideline 209. The substance is not hazardous for microorganisms under the conditions used in this test.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 3 100 mg/L
Additional information
Isopropenyl acetate (purity > 99.9%) was administered at concentrations of 625, 1250, 2500, 5000 and 10000 mg/l respectively to inoculum (activated sludge of a predominantly domestic sewage plant) according to OECD Guideline 209. The basis for effects was the respiration rate. The test was performedat 30 min and repeated after 3 hours of exposition. 3,5 -Dichlorophenol served as a positive control substance and worked as expected. The EC50 (30 min) was determined to be 5000 mg/l whereas the EC50 (3 h) was 3100 mg/l. Therefore the substance is not hazardous for microorganisms under the conditions used in this test.
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.
