- Biodegradation in water:
- readily biodegradable
Additional information
Ready biodegradability of Alcohols, C16-18 (even numbered) and C18 unsaturated, propoxylated, < 2.5 PO (CAS 70955-07-6) was investigated in two studies. The key study (Richterich, 2004) was conducted according to OECD guideline 301D and used domestic sewage. Based on O2 consumption, complete degradation of the test item was determined after 30 days. Hence, Alcohols, C16-18 (even numbered) and C18 unsaturated, propoxylated, < 2.5 PO (CAS 70955-07-6) can be classified as readily biodegradable under the strict OECD conditions.
The supporting study (Kronenberger-Schäfer, 2008) is in compliance with OECD guideline 311 and GLP and used anaerobic sludge as inoculum. After an incubation period of 62 days under anaerobic conditions, the test item reached 9% degradation based on CH4 and CO2 evolution.
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.
