Two novel series of hydroxymethylgroup‐appended quaternarynitrogensurfactants (QNSs) based on the aliphatic N‐alkyl‐trimethylammonium and aromatic N‐alkylpyridinium headgroups were synthesized from the appropriate nitrogenheadgroup precursor and 1‐bromoalkane. The QNSs were characterized using 1H and 13C nuclear magnetic resonance and infrared spectroscopy, and their purity confirmed using elemental
