Abstract
As a result of the widespread use of facial makeup many studies were reported for the determination of heavy metals in cosmetic products using different methods and instruments. Several facial cosmetics (powders and eyeliners) available in Sudan were analyzed for their contents of the heavy metals: arsenic, cadmium, lead and mercury. Samples were manufactured in different countries. The quantification of these heavy metals was performed by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). The analyses were preceded by microwave-assisted acid digestion of the products. The concentrations of the As and Cd are in the range of (2.376-6.796) and (0.2179-0.6179) ppm in the powder products and (1.504-4.084) and (0.1559-0.2959) ppm in the eyeliner products respectively. The Pb average (median) content is 3.288 and 0.0 ppm in the powder and eyeliner products. The mercury wasn

A cosmetic product is defined as being "any substance or preparation intended to be placed in contact with any part of the external surfaces of the human body, or with the teeth and the mucous membranes of the oral cavity with a view exclusively or mainly to cleaning, perfuming, changing their appearance, protecting, keeping them in good condition or correcting body odours except where such cleaning, perfuming, protecting, changing, keeping, or correcting is wholly for the purpose of treating or preventing disease” (BIS, 2010)
Today over 300 chemical toxins including dioxin were detected in human tissues that were not reported before (Shirley, 1987) February 3, 2005 the Food and Drug Administration issued an unprecedented warning to the cosmetics industry stating that the Agency is serious about enforcing the law requiring companies to inform consumers that personal care products safety has not been documented, but the safety of the ingredients in these products is looked into almost exclusively by a manufacturer-controlled safety committee called the Cosmetic Ingredient Review (CIR) panel (Shirley, 1987)
In this study we focus on toxicity of heavy metals in cosmetics, Heavy metals are metallic elements which have a high atomic weight and a density much greater than water
Summary
A cosmetic product is defined as being "any substance or preparation intended to be placed in contact with any part of the external surfaces of the human body (that is to say, the epidermis, hair system, nails, lips and external genital organs), or with the teeth and the mucous membranes of the oral cavity with a view exclusively or mainly to cleaning, perfuming, changing their appearance, protecting, keeping them in good condition or correcting body odours except where such cleaning, perfuming, protecting, changing, keeping, or correcting is wholly for the purpose of treating or preventing disease” (BIS, 2010). Today over 300 chemical toxins including dioxin were detected in human tissues that were not reported before (Shirley, 1987) February 3, 2005 the Food and Drug Administration issued an unprecedented warning to the cosmetics industry stating that the Agency is serious about enforcing the law requiring companies to inform consumers that personal care products safety has not been documented, but the safety of the ingredients in these products is looked into almost exclusively by a manufacturer-controlled safety committee called the Cosmetic Ingredient Review (CIR) panel (Shirley, 1987). Certain heavy metals are nutritionally essential for a healthy life as the building blocks of our bodies They are required for body structure, fluid balance, protein structures and to produce hormones. For example, along with other minerals are required for the electron transport system and needed for all cellular energy
