Determination of Heavy Metals in Eyeliner, Kohl Samples

Abstract

It is well known that heavy metal impurities in cosmetic products are unavoidable due to the ubiquitous nature of these elements, but should be removed wherever technically feasible. Heavy metal concentrations in cosmetic products are seen to be technically avoidable when they exceed a certain limits. In this work we chose eight sample of the most expensive eyeliner, kohl brand from the Saudi market. Twenty eight elements were determined by using inductively coupled plasma mass spectrometer (ICP-MS) and a flow injection mercury system (FIMS). Most of the elements concentration were found in the normal level but aluminum and nickel were high in some samples.
