Cosmetic

In the cosmetic industry, high viscous dispersions play an important role. These systems are very difficult to characterize with standardized techniques. The shelf-life of cosmetics can be studied with multiple light scattering. Furthermore, particle size and shape play an important role in the application of the products and their classification.
