Session: Analytical Division Poster:

When using cosmetic products, it is important to know what is being placed on top of the skin. Cosmetic products with high concentrations of heavy metals can cause skin irritation,sensitization, or allergy. There are many counterfeit cosmetics on the market that mimic name brand products. By analyzing them, the concentrations of metals can be determined which will state which products are counterfeit and which are name brand. Both types of cosmetic products were analyzed using an Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-ES). The concentrationof aluminum, cadmium, chromium, copper, iron, magnesium, lead, and zinc was found in a Tarte Concealer, a Kylie Lip Kit, and Morphe x James Charles eyeshadow palette. Statistical analysis found that there was a significant difference in the amount of magnesium in concealers and amount of iron in the lipsticks.
