[Study on the elements in cosmetics by microwave digestion-iCP-AES I. The determination of Pb, As, Cr, Cd, Sr, Bi and Se in solid state cosmetics].
A safe and effective method for the microwave digestion of solid state cosmetic samples is described. The overall digestion conditions, including pressure, power, acids and time of digestion were evaluated by analysing Pb, As, Cr, Cd, Sr, Bi and Se of routine samples with ICP-AES. This method was applied to the determination of certified materials with good agreement.
