Additional information
Studies were carried out on the degradation of A GLP-study equivalent to OECD guideline 304A is available for propylene glycol phenyl ether by soil microorganisms under aerobic condition at 25°C. Three different soil samples, a sandy soil and two sandy loam soils (classified as a Tappan series and a Londo series) were used. Rapid degradation was observed with PPH, where complete degradation occurred within 2 days. The maximum amount of 14C02 produced was 31% of the initially applied radioactivity. 14C-Intermediate compound(s), which were not identified, reached 9.2% of the initially applied radioactivity on day 2 and were not detected on day 7. Since only a 3% loss of parent compound was observed in the killed controls after 7 days, the loss of PPH in the viable microcosms can be attributed to biodegradation.
