production of solid lipstick with domestic raw materials, comparison with foreign products and measurement of heavy metals in them by atomic absorption spectrometry

Abstract: the purpose of this research is to produce a solid lipstick product from domestic raw materials and to prevent the export and support of production prosperity. on cosmetics, especially liquid lipsticks, excessive use of which can have many side effects has always been and will be important. on the other hand, production with domestic raw materials has made the business prosperous and it is possible to control heavy metals such as lead and cadmium from the source of raw material production. in addition, the methods of analyzing these products and especially measuring heavy metals, such as cd2+ and pb2+ ions, are of special importance. in addition of cd2+ and pb2+ ions determination using atomic absorption spectrometer after dry ashing sample preparation, we also use other tests such as the softening point in the dry matter and microbial tests to ensure the quality and health of the product. the amounts of cd2+ and pb2+ ions in the sample produced by domestic raw materials was determined 4.75 and 4.72 ppm respectively, which is lower than the amount of these ions in the foreign lipstick goods and the samples that produced with foreign raw materials. therefore, it was concluded that the lipstick produced with domestic raw materials, in addition to having good physical quality, contains much less heavy metals than the foreign goods available in the iranian market and the goods made with foreign raw materials.
