Concentration of chromium, manganese, iron, cobalt, copper, zinc, arsenic, selenium, silver, cadmium, mercury, lead (Cr, Mn, Fe, Co, Cu, Zn, As, Se, Ag, Cd, Hg, Pb) in some kinds of powder blush samples were determined by inductively coupled plasma - mass spectrometry (ICP-MS) after dry ashing digestion combination with wet ashing digestion. The results of analysis showed that most of the elements are in the limited range of concentration according to cosmetic management regulations (06/2011/TT-BYT; Agreement on the ASEAN harmonized Cosmetic Regulatory Scheme - appendix III…). The method has low detection limits with ppt level, the relative standard deviations (% RSD) are less than 7.5%, and the recovery of elements are in the range from 63.4 % to 95.5 %, which meets AOAC requirements for trace.
