title: Direct analysis of lipsticks by Sorptive tape-like extraction laser desorption/ionization mass spectrometry imaging.
abstract: OBJECTIVE
  The objective of this study is to create and establish a simple and rapid method for lipid evaluation in daily-use female products, namely lipsticks.
  
  
  METHODS
  This approach uses STE-LDI-MSI for fast fingerprinting of complex lipids, such as triacylglycerols, phosphoglycerols and simpler structures as free fatty acids.
  
  
  RESULTS
  This work has focused on lipsticks of several brands globally marketed. With no sample preparation, it has demonstrated to readily identify compounds of interest by integrating both full scan and MS/MS data.
  
  
  CONCLUSIONS
  A novel and rapid technique for lipid evaluation in lipsticks is presented.
