Forensic Analysis of Cosmetics 

Forensic Analysis of Cosmetics 

Thursday, February 17, 2022 | 1:00 PM - 2:00 PM Eastern
Duration: 1 hour

Overview

What is in a cosmetic? Cosmetics are a huge part of many people’s daily routine, but the science behind these quick fixes is still somewhat of a mystery to most and forensic science still has much to learn regarding this form of evidence. This webinar will provide a peek behind the curtain of cosmetics, specifically those applied to the face, and explore what makes these products work. The presenter will include an overview of ingredients commonly found in cosmetics, including typical usage levels and their purpose in these products. Some of the ingredients will be familiar to trace chemists as they are also used in more traditional forms of trace evidence, such as paint. The webinar will discuss various analytical approaches to the analysis of cosmetic products and their individual components, which should also be familiar to trace chemists. Specific emphasis will be placed on microscopy, infrared, and elemental analyses. There are specific challenges and limitations associated with analyzing cosmetics, including limited published research, mixtures of various products, contamination from biological materials, and changes to the chemical composition due to absorption and evaporation. This webinar will conclude with a discussion of how to answer specific questions, which were asked of the presenter regarding evidence from a case, like "Is this material a cosmetic?" and "Can a potential source of the material be determined?"

Detailed Learning Objectives

  1. Attendees will learn the composition of cosmetics, specifically those applied to the face.
  2. Attendees will gain an awareness of the specific materials or combination of materials that can determine whether a questioned material is a cosmetic.
  3. Attendees will understand the limitations of comparing questioned source cosmetic materials with known sources.
