In cosmetic industry, high viscous dispersions are playing an important role. These systems are very difficult to characterize with standardised techniques. Beside shelf life studies with TURBISCAN, the big challenge is the homogenisation of these products and its several components. One possible solution could be RHEOLASER CRYSTAL by monitoring the melting behaviour.Furthermore, rheological behaviour plays an important role for application of products and sensory properties. Both, the viscosity at high shear rates and viscoelastic properties at zero shear could be very interesting for R&D and application.Sometimes, drying properties of systems like make-up or nail varnishes are crucial properties for these systems.
