In the crime scene, there remain many trace evidences and research that is related to trace evidence has been conducted actively to analyze the evidence more efficiently. Stain of lipstick, one of the many trace evidence, can be good evidence to find the suspect or anyone who is connected to the crime. It is necessary to make database because the components of the lipstick is slightly different depending on the kind of lipsticks. In this study, to make database for lipstick components, twenty one samples of three colors such as red, pink and orange were prepared. And we investigated the characterization of lipstick evidence using Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) and Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR) and X-ray Fluorescence Analyzer (XRF). TOF-SIMS provides chemical information on surface of sample and their distribution without any treatment. ATR-FTIR is able to identify the molecular structure of lipsticks samples. And XRF is an instrument for analyzing component contained in the samples.
