The objective of this work was to estimate titanium and iron superficial density in eye shadows and blushes employing energy dispersive X-ray fluorescence methodology and determine other elements present in eye shadows and blushes samples of three different trademarks. A portable EDXRF system was used to analyze 36 eye shadows samples and 7 blushes samples. Quantification was performed using calibration curves with titanium and iron standards, 47.9µg/cm² superficial density, thin film type, deposited on polycarbonate membranes, both from MicroMatter Inc. Titanium and iron superficial density were measured in all the analyzed samples, calculated the ratio titanium/iron and detected other elements in the samples beyond titanium and iron.
