Postnova Analytics has published a new application note that describes a new approach for analysis of titanium dioxide nanoparticles in commercial sunscreens.
The technique, which combines Inverse Supercritical Fluid Extraction (I-SFE) and Miniaturized Asymmetrical Flow Field-Flow Fractionation hyphenated with UV-Vis and MultiAngle Light Scattering (mAF4-UV-MALS) represents a promising tool for the verification of the nano-labelling of such products.
Due to the complexity of commercial sunscreen formulations, the determination of their nanoparticle content is usually very challenging and requires a tedious sample preparation step including the application of potentially hazardous organic chemicals.
The authors report on how 5 different commercial sunscreens were investigated for their nanoparticle content using I-SFE followed by mAF4-UV-MALS analysis.
