Description of key information

Hydrolysis as a function of pH: T1/2 > 1 year at pH 4, 7 and 9 and 20°C (OECD TG 111)

Key value for chemical safety assessment

Additional information

The study consisted of two separate tests, the first test was under flow-through conditions, the second one in a closed system. This second closed system test was performed because the results with the flow-through test were unsatisfactory. The half-life (hydrolysis) of Ethylhexyl Methoxycinnamate was found to be > 1 year at pH 4, 7 and 9 at 20 °C. The degradation products that were formed could not be succesfully identified, as both TLC methods (straight phase and reversed phase) did not confirm each other.
