Abstract

Excessive and continuous use of cosmetic products containing heavy metals can lead to harmful effects. International regulations mandate limited quantities of heavy metals contamination in cosmetic preparations to ensure consumer safety. This research aims to evaluate heavy metal and microbial contamination levels in selected cosmetic products available in the Palestinian market. We collected 35 samples randomly from 23 companies, representing four product types, and analyzed them for the presence of seven heavy metals: zinc (Zn), cadmium (Cd), lead (Pb), chromium (Cr), iron (Fe), copper (Cu), and arsenic (As) using an atomic absorption spectrometer. We also interviewed pharmacists who sold these cosmetics to assess their knowledge of allowed limits and toxic effects associated with increased heavy metal content in cosmetics. The results indicated that all tested products exceeded the allowed limit for Cd (9.5 ± 2.3 ppm), Cu (33.8 ± 9.2 ppm), and Zn (151.0 ± 7.4 ppm). However, none of the tested samples showed microbial contamination. These findings underscore the significant heavy metal contamination of cosmetics present in the Palestinian market. Thus, there is a pressing need to register and quality-test all cosmetic products sold in the Palestinian market and to raise the pharmacists' awareness and knowledge regarding heavy metals in cosmetics.

对巴勒斯坦市场上选定的化妆品进行重金属和微生物检测。

过量和持续使用含有重金属的化妆品会导致有害影响。国际法规规定化妆品制剂中的重金属污染限量，以确保消费者安全。这项研究的目的是评估在巴勒斯坦市场上可获得的选定化妆品中的重金属和微生物污染水平。我们从23家公司随机收集了35个样品，代表4种产品类型，并使用原子吸收光谱仪分析了七种重金属的存在:锌(Zn)，镉(Cd)，铅(Pb)，铬(Cr)，铁(Fe)，铜(Cu)和砷(As)。我们还采访了销售这些化妆品的药剂师，以评估他们对化妆品中重金属含量增加的允许限度和毒性影响的了解。结果表明，所有检测产品的镉(9.5±2.3 ppm)、铜(33.8±9.2 ppm)和锌(151.0±7.4 ppm)均超过允许限量。然而，所有测试样本都没有显示出微生物污染。这些发现强调了巴勒斯坦市场上存在的化妆品的严重重金属污染。因此，迫切需要对在巴勒斯坦市场上销售的所有化妆品进行登记和质量测试，并提高药剂师对化妆品中重金属的认识和知识。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
