Description of key information

Readily biodegradable: 78% (BOD) in 28 days, 10-day window met (OECD TG 301F)
Ultimately anaerobically biodegradable: plateau at 67% after 79 days (ISO 11734: 1995)

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Ethylhexyl Methoxycinnamate was found to be readily biodegradable in 3 separate studies. The results of the studies were 78% biodegradation in 28 days (OECD TG 301F), 71% biodegradation in 28 days (OECD TG 301C) and 70 -80% biodegradation in 28 days (OECD TG 301F). The poor water solubility does not seem to limit the rate of degradation to a significant extent. The key study was chosen based on the highest reliability score. Besides these ready biodegradability studies, an ultimate anaerobic biodegradability study is available, which showed that the substance is even ultimately anaerobically biodegradable (plateau at 67% after 79 days (ISO 11734: 1995).
