MERCURY CONTENT IN BULGARIAN COSMETIC PRODUCTS
Journal Title: Българско списание за обществено здраве (Bulgarian Journal of Public Health) - Year 2017, Vol 0, Issue 3
Abstract
Mercury is considered by the World Health Organization to be one of the ten most toxic chemicals that are particularly dangerous to human health (WHO, 2013). Mercury and its compounds refer to the substances in cosmetic products prohibited by Regulation (EC) 1223/2009, except for the special cases listed in Annex 5 of the Regulation - preservatives thiomersal and phenylmercury salts authorized for use in eye cosmetics. Their maximum admissible concentration in the finished product is 0.007 % (as mercury). The study examined the content of mercury in various Bulgarian cosmetic products (n = 823) divided into three groups: hair cosmetics (n = 237), facial cosmetics (n = 234) and cosmetic products for the body (n = 352). Mercury analyzes were performed by means of DMA 80 (Direct Mercury Analyzer), Milestone. In most of the products tested, the concentration of the element is below the limit of quantification of the analytical procedure (LOQ 0.008 mg/kg). The presence of mercury in concentrations of 0.0083 ÷ 0.040 mg/kg was found only in 24 (2.9%) of the product tested; almost all henna samples (10/11) contain Hg, albeit at very low concentrations (0.013 ÷ 0.028) mg/kg. The results of the study show that the Bulgarian cosmetic products tested comply with the European legislation regarding the mercury content. No mercury concentrations above 1.0 mg/kg, tolerable level as a technical contamination according to the guideline „Indicators and permitted levels for microbiological and chemical purity of cosmetic products and methods for checking compliance with these parameters“ have been established in the collected database.
