  • Alkylphenol ethoxylates have been used extensively as nonionic surfactants in industrial processing, household and institutional cleaning products. They are apparently degraded microbially to alkylphenol. Alkylphenol has been shown to possess estrogenic properties and, therefore, is an 'endocrine disrupter' that has significantly influence on sexual and reproductive development.(omitted)

  • Vulcanized rubber containing three kinds of oligomeric resins such as cashew resin, t-octylphenol formaldehyde resin and terpene modified wood rosin has been characterized by simultaneous pyrolysis methylation-gas chromatography/mass spectrometry (SPM-GC/MS). After methylation by the SPM method using tetramethylammonium hydroxide, the methylated pyrolyzates of the corresponding resins were detected with higher sensitivity than underivatized pyrolyzates without any interferences from other ingredients of vulcanized rubber.
