Arsenic and Mercury Content Determination in Commercial Cosmetics Products by Atomic Absorption Spectroscopy

Abstract

Abstract:Toxic elements are present everywhere in nature and even in raw materials and pigments used in the manufacture of cosmetics. Human bodies daily exposed to toxic elements that can be found in trace amounts in cosmetic products. These elements such as arsenic and mercury can cause local skin damage or possible, their absorption through the skin or swallowed. In this paper we determined the content of arsenic and mercury in ten lipstick samples and eight nail polishes samples by atomic absorption spectroscopy (AAS). Acid digestion with 0,1 M HCl or HNO 3 -HCl was performed. A very low concentration of Hg and As have been found in all samples in both extracts (ranged, 0.0001-0.0004 μg/g and 0.02 -0.04 μg/g respectively).

Quality Concerns of Lip Care Cosmetics and Applicable Regulatory Framework: Need for a Harmonized Cosmetovigilance Programme

“…29 According to the research studies, it is known that Pb enters the body through the gastrointestinal tract and lungs, 30 it destroys red blood cells and reduces their oxygen-carrying capacity to necessary tissues, resulting in anaemia. 31 Cadmium Through research it is widely acknowledged that in the cosmetics Industry, Cd is used in colour pigments. It can be used in a variety of cosmetics, although it is most commonly found in lipstick, polluted air, cigarettes, and contaminated food.…”

“…27 It has been shown to reduce gonadotropin binding, altering the activity of steroidogenic enzymes. 31 Furthermore, a synergistic impact between Pb, Cd, As, and Hg might result in cognitive impairment. 23 Chromium Cr levels were found to be highest in lipstick and eyeliner samples.…”

Optimization and Analytical Behavior of Electrochemical Sensors Based on the Modification of Indium Tin Oxide (ITO) Using PANI/MWCNTs/AuNPs for Mercury Detection

“…Nonetheless, it may cause skin rashes and scarring and reduce skin resistance to bacterial and fungal infections. Most importantly, being a neurotoxin, mercury exposure has been reported to cause adverse health effects in humans, especially neurological disorders including anxiety, depression, psychosis and peripheral neuropathy, as well as kidney dysfunction [ 1 , 2 ]. Monitoring the level of mercury ions (Hg 2+ ) in cosmetic products is therefore of fundamental importance.…”

“…The conventional analytical methods for the detection of Hg 2+ usually rely on the use of advanced instruments based on spectrometric and chromatographic techniques, such as atomic absorption spectrometry (AAS) [ 1 , 5 ], inductively coupled plasma mass spectrometry (ICPMS) [ 6 ], graphite furnace atomic absorption spectrometry (GFAAS) [ 2 ], inductively coupled plasma atomic emission spectrometry (ICP-AES) [ 7 ] and liquid chromatography inductively coupled plasma mass spectrometry (LC-ICP-MS) [ 8 ]. While such approaches have been proven to be highly accurate and sensitive, the complex, expensive and time-consuming procedures associated with these methods call for a simpler alternative for daily analysis and on-site detection in a large number of samples in the field.…”

Optimization of Kieldahl digestion procedure for determination of mercury in lipstick by Box-Hunter design

“…The highest proportion of Hg was observed in skin lightening creams (mean concentration 1.008 ppm). Heavy metals were found in cosmetic products of different countries markets in Khyber Pakhtunkhwa, Pakistan, Caribbean, Banja Luka (Jelić, Antunović, & Đermanović, 2017;Mohammed, Mohammed, & Bascombe, 2017;Ullah et al, 2017). In Vietnam, some authors have identified banned substances in cosmetics.…”
