Abstract

The aim of this review is to discuss and compare the current trends in liquid–liquid and solid–liquid extraction procedures applied to the analysis of cosmetics. Although classical sample preparation procedures are mostly used in labs, the new trends in sample preparation that provide more effective analyte extractions from these complex matrices are gradually being introduced. Drawbacks inherent to conventional or classical extraction procedures in cosmetic samples are also considered. A detailed revision in the period January 1992 to March 2012 about current sample preparation techniques such as liquid-phase microextraction (LPME), microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), accelerated solvent extraction (ASE) and supercritical fluid extraction (SFE) applied to cosmetics is given. In general, these procedures have given rise to faster, greener and more effective extraction techniques for cosmetic analysis with regard to conventional procedures.
