Abstract
This application note demonstrates evolved gas analysis (EGA) and multi-step pyrolysis (MSP) with GC/MS on two different mascara samples.
Introduction
Cosmetics include a wide array of products, such as lipsticks, mascara, eyeshadow, moisturizers, foundations, to enhance the appearance of the face or body. In US alone, the cosmetic industry contributed 1.5% of the gross domestic product (GDP), which is over $250 billion. The chemical formulation of cosmetics is extremely complex, and are grouped into common ingredients and proprietary ingredients. This wide range of substances in complex matrices is challenging for quality control process. The traditional component analyses by wet chemistry require large sample amount and are time-consuming through solvent extraction steps. This application note proposes quicker and easier alternatives by combining EGA and MSP GC-MS analysis to separate ingredients based on volatility.
