Zusammenfassung:	Gas chromatography coupled with mass spectrometry and protonic nuclear magnetic resonance used directly or on fractions obtained by preparative thin layer chromatography, allow identification of the main molecule in commercial samples of PABA (Cas RN 150-13-0), PEG-25 PABA (Cas RN 116242-27-4), glyceryl PABA (Cas RN136-44-7), ethyl dihydroxypropyl PABA (Cas RN 58882-17-0) or octyl dimethyl PABA (Cas RN 21245-02-3).
