چکیده
In this study, Skin-lightening creams commonly sold in Mbarara municipality were analyzed for chemical parameters (pH, thermal stability and fatty substance content), total hydroquinone, Lead, Mercury, Arsenic contents. Total heavy metal content was determined by atomic absorption spectrophotometry. The levels of hydroquinone using High Performance liquid chromatography (HPLC). All the showed detectable mean mercury, ranging from 0.07±0.01ppm to 0.33±0.01ppm. Only 26.31% lead 15.79% recorded arsenic. ranged 0.54±0.02% 4.47±0.02%. passed tests. However, all had very low pH values below recommended 4.5- 8.5 ranges Uganda National Bureau Standards (UNBS). arsenic samples less than UNBS, European Union US Food Drug Administration’s acceptable limits. 84.2% cream contained higher WHO limit 2%. use such may serious health hazards. While concentrations metals detected do not pose any potential risk consumers, repeated application these cause a cumulative effect over prolonged exposure. skin irritations. Therefore, community needs be sensitized on implications lightening UNBS should conduct periodic analysis ascertain metals, requirements as well encourage manufacturers state exact bleaching agents their creams.
