The survey of analytical methods for sample preparation and analysis of fragrances in cosmetics and personal care products

Fragrances most widely utilize in cosmetics and personal care products. These are known as allergens and emerging organic contaminants that induce the adverse effects on human health. In addition, dealers are tempted to adulterate the products by adding lower cost materials. It is therefore essential to detect fragrances in raw materials, cosmetics, and personal care products. The aim of this review is a survey of the main sample preparation and analysis methods proposed in previously published works dealing with the detection of fragrances in cosmetics and personal care products. Different sample preparation methods were utilized according to the matrix complexity e.g. dilution for the simple matrix, and headspace, direct, and tandem methods for the complex matrix. Also, different methods have been used for the analysis of fragrances in cosmetics and personal care products, investigated in four parts: chromatography, spectroscopy, mass spectrometry and electronic nose methods.
