Description of key information

The stability of N-(1 ,3-dimethylbutyI)-N-phenyl-1,4-phenylediamine (6PPD) in aqueous test solutions was investigated in a hydrolysis test similar to OECD Guideline 111 (Hydrolysis as a function of pH). 
The tests were performed in order to examine the stability under conditions simulating those in the environment (pH 7, presence of light , air and
algae nutrion medium). The half life of 6PPD was 8 hours at 26°C and 4-Hydroxydiphenylamine (CAS 122-37-2) was identified as the major aromatic
intermediate of (6PPD) degradation. ( Bayer Industrial Services, 2003)

Key value for chemical safety assessment

Half-life for hydrolysis:
8 h
at the temperature of:
26 °C
