Description of key information

A simulation study indicates that benzyl butyl phthalate degrades rapidly in natural river water.

Key value for chemical safety assessment

Additional information

The ready biodegradability of benzyl butyl phthalate, as shown in screening tests, means that a key simulation study is not required.
An existing simulation study (Saeger, 1982) reports that the half life of the test substance is 0.5 and 1.4 days with initial test substance concentrations of 50 and 500 µg/L respectively. This is used as a supporting study.
