The method describes the determination of heavy metals (arsenic, cadmium, lead and mercury) in cosmetic products.
Organic matter in sample is digested by high pressure microwave digestion and determine the amount of heavy metals, i.e. arsenic (As), cadmium (Cd), lead (Pb) and mercury (Hg) by using graphite furnace-atomic absorption spectrophotometer (GF-AAS), cold vapour-atomic absorption spectrophotometer (CV-AAS) and hydride generation-atomic absorption spectrophotometer (HG-AAS).
