Determination Of Some Trace Elements In Some Lipstick Products By Inductive Coupled Plasma-Mass Spectrometry

Abstract

Cosmetics have been attracting the attention of humanity since it existed. Over the years, the reach of the cosmetics industry has increased exponentially. In recent years, cosmetic manufacturers have developed many formulations on cosmetic products that are brighter in color, more permanent and not easily affected by external factors. However, heavy metal powders are used while producing these formulations especially inside in dyestuffs and stabilizers. Cosmetic products can be absorbed through the skin and cause systemic toxicity. Hundreds of chemicals are used in many cosmetic products such as make-up products, shampoos, creams, aftershaves, and these chemicals may cause significant health problems. Thus, this study is designed to investigate the heavy metal content of lipstick samples which are used extensively by women. Determination of aluminum (Al), chromium (Cr), iron (Fe), nickel (Ni), copper (Cu), zinc (Zn), elements in 35 different lipstick samples (including 15 brands) were performed by Inductively Coupled Plasma-Mass Spectrophotometer (ICP-MS) device. Before the analysis, two different solubilization methods, wet solubilization and dry ashing, were applied to the samples in order to take the metals in the lipstick samples into inorganic environment
