Comparative analysis of heavy metal content of unregulated facial whitening creams and branded facial whitening creams.
Toxicology Reports 2024 June
The present study was conducted to evaluate potential health risks of Omani cosmetics considering the dangers and adverse effects on health caused by unregulated and unlabelled cosmetic products. Therefore, this current study is to examine the toxic heavy metals of unregulated facial whitening creams that are available in the Omani market and compare them with branded facial whitening creams. A total twenty-two samples were purchased from the Souqs/markets of all eleven governorates of Oman and their heavy metals content was determined by using Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). The sample was digested by using ultra wave microwave at 180 °C. The percentage of heavy metals present in the unregulated whitening creams were compared with the heavy metals content of two randomly selected and branded whitening creams. The results showed that most of the unregulated samples contain significant amount of chromium, cooper and lead. In comparison, the branded face creams contained only the permissible amount of the heavy metals tested. The maximum arsenic content was found in a sample collected from Al Batinah South region (1.74 ppm). The maximum cadmium content was found in a sample collected from Al Wusta region (2.02 ppm). The maximum cobalt and chromium content were found in the samples collected from Al Buraimi region (0.10 ppm) and Dhofar region (8.04 ppm) respectively. In conclusion, unregulated face creams are not safe for human consumption because they contain significant levels of heavy metals that exceed the permissible limits.
