Description of key information

The test conducted according to the OECD Guideline 301 C (Ready Biodegradability: Modified MITI Test)
N-(1,3-dimethylbutyl)-N'-phenylbenzene-1,4-diamine showed 2% degradation after 4 weeks. (MITI, 1995)

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Based on BOD, ca. 2 % of 6PPD was biodegraded; based on HPLC, approx. 92 % of 6PPD was degraded and the following degradation products were determined: Phenylbenzoquinone imine, p-benzoquinone, 1,3-dimethylbutylamine, 4-anilinophenol, aniline
