Abstract

A simple and fast method is proposed to analyze commercial personal perfumes. Our method includes measurement of phthalates, known to be major sources of endocrine disruptor chemicals (EDC), which originate from the less volatile fraction of perfumes. The quantification of phthalates were carried out directly with no sample preparation required on 30 samples of commercial products using gas chromatography and mass spectrometry (GC-MS) as a detector. The total concentrations of 15 investigated compounds ranged from 17 to 9650 mg/L with an average of 2643 mg/L. The highest total concentration was found in cologne. Diethyl phthalate (DEP), diisobutyl phthalate (DiBP), di(2-ethylhexyl) phthalate (DEHP), and di-n-butyl phthalate (DBP) were detected in appreciable concentrations. Further, it was found that the composition of counterfeit samples varied widely from that of authentic products. The composition of old products was different from that of recent perfumes, which contain less harmful chemicals, attributed to the ban on some phthalates in Europe due their toxicity. It should be noted that older and contaminated products are not equivalent to authentic products when considering quality, safety, and probably effectiveness. Older and nonapproved perfumes contain chemicals that are not allowed for commercial use and may contain toxic impurities.
