Characterization methods for inorganic nanoparticles in consumer products

Thanks to its many advantages, the spICP-MS technique is becoming the method of choice for routine analysis. It can be used in various industrial sectors—such as cosmetics, food and agriculture, pharmaceuticals, and textiles—for product quality control, regulatory compliance, or stability monitoring (dissolution, agglomeration/aggregation of nanoparticles). This technique is often the first-line method and can be supplemented by other techniques if morphological or structural details are required. Application examples are presented in Table4 for the characterization of inorganic particles (TiO₂, ZnO, and Fe₂O₃) in raw materials and various consumer products. The particle size distribution properties (average size, median size, % < 100 nm) and their concentrations vary significantly depending on the product category. Among...
