Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One study, investigating the ready biodegradability of methyl laurate (CAS 111-82-0), was used as read across for Fatty acids, C8-18 and C18-unsatd., Me esters (CAS 67762-37-2). This substance is structurally and compositionally related to Fatty acids, C8-18 and C18-unsatd., Me esters. In this GLP-study (Ministry of Economy, Trade and Industry, Japan, 1995) according to OECD 301C (Modified MITI Test) mixture of sewage, soil and natural water was used as inoculum. At test termination after 28 days a degradation of 78% was observed. The 10-d window concept does not apply to the MITI method. The read across substance can be classified as readily biodegradable according to OECD criteria. Based on the category it can be concluded that Fatty acids, C8-18 and C18-unsatd., Me esters (CAS 67762-37-2) is also 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.
