Abstract

(1) Background: Clays are popular raw materials of natural origin used in cosmetology, beauty salons, and home care. They have moisturizing, soothing, cleansing, disinfecting, detoxifying, and regenerating properties, and can be used externally in the form of poultices or internally in solution form. Though they are characterized by a rich and diverse mineral composition and are considered safe for the body, their use can expose users to harmful elements including mercury. (2) Materials and methods: This study analyzed mercury (Hg) concentrations in samples of cosmetic clays available on the Polish market. Hg analysis was performed using the AAS method with an AMA 254 analyzer. The clays differed in type/color and were purchased from different manufacturers. (3) Results: The mean Hg content in all the tested samples was 28.91 µg/kg, with a range of changes of 1.87-200.81 µg/kg. The highest concentrations of Hg were found in green (AM = 53.26 µg/kg) and white (AM = 52.80 µg/kg) clays, while the lowest were detected in purple (AM = 2.56 µg/kg) and blue (AM = 3.69 µg/kg) clays. The differences in Hg content between individual types of clay were statistically significant. (4) Conclusions: Due to the presence of Hg found in all the samples of cosmetic clay tested, it is likely that these products need to be tested for their metal contents.

化妆品粘土中汞的浓度分析。

(1)研究背景：粘土是一种天然原料，广泛应用于美容、美容院、家庭护理等领域。它们具有保湿、舒缓、清洁、消毒、排毒和再生的特性，可以外用膏药的形式，也可以内用溶液的形式。虽然它们的特点是矿物成分丰富多样，被认为对身体是安全的，但它们的使用可能会使使用者接触到包括汞在内的有害元素。(2)材料和方法：本研究分析了波兰市场上化妆品粘土样品中的汞（Hg）浓度。汞分析采用原子吸收光谱法，采用AMA 254分析仪。这些粘土的种类和颜色各不相同，而且是从不同的制造商购买的。(3)结果：所有样品中汞的平均含量为28.91µg/kg，变化范围为1.87 ~ 200.81µg/kg。汞含量最高的是绿色粘土（AM = 53.26µg/kg）和白色粘土（AM = 52.80µg/kg），最低的是紫色粘土（AM = 2.56µg/kg）和蓝色粘土（AM = 3.69µg/kg）。不同类型粘土间汞含量差异有统计学意义。(4)结论：由于所有化妆品粘土样品均含有汞，可能需要对这些产品进行金属含量检测。

期刊介绍： Toxics (ISSN 2305-6304) is an international, peer-reviewed, open access journal which provides an advanced forum for studies related to all aspects of toxic chemicals and materials. It publishes reviews, regular research papers, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in detail. There is, therefore, no restriction on the maximum length of the papers, although authors should write their papers in a clear and concise way. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of calculations and experimental procedure can be deposited as supplementary material, if it is not possible to publish them along with the text.
