The results of this study demonstrate that 6,6'-[[3,3',5,5'-tetrakis(1,1-dimethylethyl)-[1,1'- biphenyl]-2,2'-diyl] bis(oxy)]bis-dibenzo[d,f][1,3,2]-dioxaphosphepin did not meet either the pass level (> 60% DO2) or the 10-day window criteria for ready biodegradability in the Manometric Respirometry test. Degradation reached a maximum of 16.2% of THOD for the test material at the end of 28 days.
