                                           Image 1: List of ingredients present in lipstick



             The majority of the ingredients present in lipstick contain harmful toxins. For

             example, methylparaben is restricted in Europe because of the cancer risks it
             poses. But these ingredients

             often fall under the category of hidden ingredients which means it’s impossible

             for consumers to be aware of the toxic substances present in them.


             FORENSIC PERSPECTIVES LIPSTICK




             Earlier  cosmetic  smears  were  considered  futile  and  ineffective  but  now  it  is
             considered major physical evidence since it’s easily transferred during crimes.



             Analytical techniques used in the examination of lipsticks are:

                  Thin layer chromatography (TLC)
                  Atomic Absorption Spectroscopy(AAS)

                  High-performance liquid chromatography (HPLC)
                  Inductively coupled plasma mass spectroscopy (ICP-MS)

                  High-resolution  continuum  source  graphite  furnace  atomic  emission
                  spectroscopy (ICP-OES)

                  Gas chromatography-mass spectroscopy (GC-MS)
                  Neutron activation analysis (NAA)

                  Raman spectroscopy
                  ATR-FTIR
