Radiological assessment of pharmaceutical clays.
The suitability for pharmaceutical and cosmetic application of fourteen clay samples, eight
raw and six commercialized samples, from Minas Gerais and São Paulo states, Brazil, were
evaluated and their mineralogy, chemical and radiological composition were determined.
Results indicated that the samples are composed mainly of quartz, kaolinite and feldspar,
enriched in AlO and TiO, Cd, Cs, Sb, Se, Th, and U and depleted in SiO, MgO, PO, and Ca.
Concentrations found are unlikely to present any harm in topical applications, and all the …
