Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
T-shaped rubber samples of defined composition are immersed in distilled water of pH 4 for 15 days. Water samples were analyzed for p-phenylenediamine derivatives by UV-spectrophotometric measurements using a calibration curve.
GLP compliance:
no

Results and discussion

Any other information on results incl. tables

After 15 days of contact between the rubber samples and the water, approximately 1,6% of the 1,4-benzenediamine, N,N'-mixed Ph and tolyl derivs. leached from the rubber into the water phase. Two other tested p-phenylenediamines (N-isopropyl-N'-phenyl-p-phenylenediamine and N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine) respectively showed 86.2 and 44.7% of antioxidant leaching from the rubber samples.
