Description of key information
Diisobutyl phthalate was found not to be inhibitory to microorganisms at a concentration of 14.5 mg/L.
Key value for chemical safety assessment
Additional information
In the toxicity control of a guideline biodegradation study with activated domestic sludge (Clarke, 2010) the 14 day biodegradation of sodium benzoate exposed together with the test item was 55%. ≥ 25 % degradation is considered to be an indication of a non-inhibitory substance according to OECD 301 guideline. Thus the test item concentration of 14.5 mg/L, is considered to be an applicable NOEC.
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.
