Description of key information

Readily biodegradable: 78% in 28 days (OECD 301C, Modified MITI Test)

Key value for chemical safety assessment

Additional information

One study evaluating the biodegradation potential of methyl laurate (CAS No. 111-82-0) is available (Japanese Ministry of Economy, Trade and Industry, 1995). In this GLP-study, conducted according to OECD 301C, a mixture of sewage, soil and natural water was used as inoculum and O2consumption monitored as indicator of biodegradation. After 28 days of incubation, the test substance reached 78% biodegradation. Since the 10-day window concept does not apply to the MITI method, methyl laurate can be considered readily biodegradable according to OECD criteria.
