It is a hydrated magnesium silicate, formed naturally by the alteration of other minerals. This means that talcum powder may be composed of additional minerals other than talc (chlorites, carbonates, quartz, amphiboles, among others).<br \/>\nThe characteristics of talc make it a unique raw material with a wide variety of applications in different industrial sectors, including the pharmaceutical-cosmetic sector.<br \/>\nSamples of talcum powder were studied and their quality for pharmaceutical-cosmetic use was evaluated using the standards of the European Pharmacopoeia and different advanced complementary methods such as: XRF, DRX, ICP-masses, SEM-EDX, calcimetry and atomic absorption.<br \/>\nMost of the samples presented high relative purity in the mineral species talc, with a content of over 90% in most cases. This indicates good mineral quality for cosmetic use. Most of the samples also have good Pharmacopoeia quality and are therefore suitable for pharmaceutical-cosmetic use.<\/p>\n<p><strong>Keywords:<\/strong> Talc; European Pharmacopoeia; Mineral quality; Pharmaceutical-Cosmetic Use; Impurities.<\/p>\n<p><strong>Directed by:\u00a0<\/strong>Mar\u00eda Virginia Fern\u00e1ndez Gonz\u00e1lez<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; Talc is a mineral species belonging to the Phyllosilicates (class of Silicates).
