A broad collection of pigment, powder coatings, and ink products exist as particulate form in both the raw material and finished product. The particle size distribution determines their appearance, quality, functionality and processability, thus measuring the pigment particle size is as an excellent predictor of final product performance. Moreover, particle size of pigment particles in paint is a critical parameter that affects surface finish. As for example, cosmetic industry is always looking for the best mix between creativity and innovation and color pigments cover a fundamental role in this. To create metallic effects, white, interference, reflections, particles with adequate characteristics have to be selected.
CLASSIZER™ ONE is an enabling device supporting product formulation, thanks to its performances in charactering particle size distribution, composition, shape, best surfactant and the stability of pigments, inks and cosmetics powders.
The case of pigments for cosmetics
Any cosmetic product includes micro and nanoparticles of different size distribution, different shape and different material composition (kaolin, talc, metal oxides, mica). Measurement of the particle size distribution is required both for the development of novel products and for the quality control during the production process. CLASSIZER™ ONE covers a wide range of size distribution and allows reliable characterization of spherical and non spherical powder of different materials.
The case of inks
Inks are a liquid dispersion of pigments for writing or printing. The product is a mixture of a number of components, the majority being the pigment particles in some liquid carrier. A number of additives are usually included to modify viscosity, drying, stability, or color characteristics. Particle size of the pigment particles can significantly affect the color strength, surface finish, and durability of the final product. In addition, the particle size of the pigments must be small enough that they do not block the nozzles of the printing mechanism.
