Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One experimental study investigating the biodegradability of Reaction mixture of Glycerol 1,3- di(acetate), glycerol acetate and triacetin is available. The study was performed according to OECD 306 with natural seawater as inoculum (GLP). A biodegradation of 108.5% (3.5 mg/L test material) and 81% (4.5 mg/L test material) was observed after 28 d. Biodegradation in seawater is expected to be slower than that in tests with freshwater and activated sludge as inoculum. According to the “Guidance on information requirements and chemical safety assessment / Chapter R.7b: Endpoint specific guidance” published by ECHA (2008) a removal of > 60% after 28 d in a study according to OECD 306 can be used as evidence that the substance is expected to fulfill the requirements for readily biodegradability. Therefore, Reaction mixture of Glycerol 1,3- di(acetate), glycerol acetate and triacetin can be classified as readily biodegradable.
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.
