Additional information

In a key study according to the slightly modified OECD (301 D), EU and ISO test guidelines under GLP (closed bottle test) Phosflex 71B was found to be readily biodegradable (61% degradation in 28 days). As Phosflex 71B did not cause a reduction in the endogenous respiration, it is considered non-inhibitory to the inoculum.
