pigmenthaltigen

Pigmenthaltigen is an adjective used to describe substances or formulations that contain pigments as colorants. In pigmenthaltigen systems the color arises from solid pigment particles dispersed in a binder or medium, rather than from dissolved dye molecules. The appearance depends on particle size, distribution, and the optical properties of the medium, including scattering and absorption.

Pigments are typically insoluble in the surrounding medium. Achieving a uniform color requires milling and efficient dispersion, often with wetting agents and dispersants, as well as stabilization to prevent sedimentation or settling. Common inorganic pigments include titanium dioxide for white, iron oxides for red, yellow or brown tones, and carbon black for black. Organic pigmentary systems include phthalocyanines (blue/green), quinacridones, and other stable pigments. Pigments can be opaque or transparent, and their suitability varies with the binder and the intended application.

Applications of pigmenthaltigen formulations are widespread and include paints and coatings, plastics, inks, and cosmetics. They are valued for opacity, lightfastness, chemical stability, and resistance to migration. However, they often require more energy-intensive processing to achieve a stable dispersion, and some pigments may pose handling or environmental concerns related to manufacturing, nanoparticle exposure, or end-of-life disposal.

In sum, pigmenthaltigen formulations rely on dispersed pigment particles to produce color, offering advantages in opacity and durability while requiring careful formulation to ensure stability, color strength, and compatibility with the medium.
