Forensic analysis of red lipsticks using ATR-FTIR spectroscopy and chemometrics

Lipsticks are used on routine basis, and due to its prevalence, it can be encountered at the crime scene as trace transferred evidence. Analyses of such exhibits can provide corroborative evidence to link the suspect with the victim or with the crime scene. In the present study, 38 different red shade lipsticks of 20 different manufacturers were analyzed using ATR-FT-IR (attenuated total reflectance-Fourier transform-infrared) spectroscopy....
