| 520 | 3 | |a Instrumental neutron activation analysis (INAA) has been used to determine some trace, minor and major elements in some cosmetic samples. These samples have been randomly selected from the Egyptian market. Some of these cosmetics are imported from the world market and the others are manufactured in Egypt. Up to 25 elements have been quantitatively determined in selected cosmetic samples. These elements are: As, Br, Ba, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Sb, Sc, Sm, Rb, Ta, Tb, Th, U, W, Yb and Zn. Two certified standard reference materials have been used to assure the accuracy and precision of the technique, which are IAEA-405 and SL-1. Two different γ-radioactivity counting systems have been used and compared. Some of the analyzed samples contain some elements, which according to the list of the European Union must not be present in cosmetics. Moreover, some of these elements are present in a very high concentration. Thus, some of the analyzed samples contain arsenic, antimony, chromium and cobalt with the following respectively concentration ranges, in ppm, 0.37-3.67, 0.14-5.36, 2.94-29768 (∼3) and 0.52-4.12. | |
