Key value for chemical safety assessment
Additional information
Several tests on the ready biodegradability of the substance are available.A guideline study performed according to OECD 301B determined the CO2 evolution within 28 days. The test detected a degradation rate of ca. 20 %. This result is supported by three studies conducted in compliance with OECD 301C. Based on O2 consumption a degradation rate of less than 10 % was determined in all three tests.
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.
