While the first selection criterion is often an aesthetic one, the consumer also wants a product that is practical to use and provides the desired finish and performance. For that, the perfect nail gel or polish should feel relatively liquid for an easy brush application but without flowing outside the nail. The drying or curing time should be as low as possible and lead to a smooth surface for a flawless appearance. Finally, it is also desirable for the manicure to be long-lasting, without it being too difficult to remove.
Using advanced NETZSCH thermal and rheological analysis techniques, we unravel the mysteries of nail gel curing:
Differential Scanning Calorimetry (DSC) and rotational rheometry are two complementary methods for the characterization of the curing of nail gels. Both methods highlight the curing speed. The new NETZSCH DSC 300 Caliris® additionally provides information about the energy released during curing, while measurements with the Kinexus rotational rheometer compare the properties of the different products during and after curing.
From temperature dynamics to viscosity changes, the research with NETZSCH instruments provides a new perspective for quality assurance in the nail care industry.
