DETECTION OF HEAVY METALS IN COSMETICS

Abstract

Metals are commonly used in cosmetic products for blocking ultraviolet light or coloring pigments. However some metals exceed specific concentrations and can cause serious safety issues such as skin troubles and allergies. Therefore it is important to measure the exact amount of metals in cosmetic products. However the exact concentrations of metals in cosmetics that contain many organic and inorganic materials like oils, polymers, waxes, surfactants, and metallic powders are difficult to analyze due to the matrix effect. In the present investigation two different heavy metals i.e. lead and cadmium in cosmetics were analyzed using Flame Atomic Absorption Spectroscopy (FAAS). Commercial products in liquid phase were prepared for analysis and spiking solutions were added to analyze.

Keywords: Cosmetics, Cadmium, FAAS, Lead.
