Inductively coupled plasma-mass spectrometry (ICP-MS) detection of trace metal contents of children cosmetics

Abstract

AbstractConsumption of cosmetic products in daily life in order to improve skin quality or appearance is becoming quite common. Over time, it may expose consumers to skin problems and effects caused by the absorption of chemical elements. Clean cosmetic production is important for our health. However, heavy metals can be found as impurities in raw materials or as by-products of the cosmetic production process. Women's ingestion and exposure to organic and inorganic contaminants in cosmetics through dermal absorption, due to reasons such as personal habits and characteristics of the living environment, may contribute to carcinogenic risks following daily dietary exposure. NCS ZC 81002b (Human Hair) was performed as a certified reference material in method validation. This work was conducted to evaluate element concentrations of selected elements (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Hg, Cd and Pb) in 3 different brands of children's cosmetic products such as bright and colorful 22 eye shadows (7 different colour) 4 lipsticks (3 different colour) and 4 nail polishes (3 different colour) used by children in Turkey. The sample solutions were analyzed with the inductively coupled plasma mass spectrometry (ICP-MS) technique after the microwave digestion system. Consequently, the highest concentration of Al used as pigment was found in the eye shadow, lipstick and nail polish samples for the 3 brands, while the Se concentrations were the lowest in lipstick samples. The results of As, Cd, Hg, Pb, which are restricted or banned for use in cosmetic products in most countries, are below the limits set by the Food and Drug Administration (FDA) and Health Canada Product Safety Laboratory (PSL).
