Matrix solid-phase dispersion (MSPD) is a very suitable analytical technique for the extraction of these compounds providing a simple, low cost sample preparation, and the possibility of performing both extraction and clean-up in one step, reducing possible contamination and analyte losses. This extraction technique has been successfully applied to many cosmetics ingredients allowing obtaining quantitative recoveries. A new very simple micro-MSPD procedure performing the disruption step in a vial is proposed for the gas chromatography-mass spectrometry (GC-MS) analysis of 66 chemicals usually present in cosmetics and personal care products. The method was validated showing general recoveries between 80% and 110%, relative standard deviation (RSD) values lower than 15%, and limits of detection (LODs) below 30 ng·g−1. The validated method was applied to a broad range of cosmetics and personal care products, including several products intended for baby care PB MDPI YR 2014 FD 2014 LK http://hdl.handle.net/10347/23705 UL http://hdl.handle.net/10347/23705 LA eng NO Celeiro, M.; Lamas, J.P.; Llompart, M.; Garcia-Jares, C.
