Take pearlescent pigments as an example, pearlescent pigments are a class of pigments with pearl luster, which are deposited on the substrate (generally natural mica, synthetic mica, glass sheet and other sheet-like materials) above a layer or alternately deposited multiple layers of metal oxides or non-metallic oxides and formed a flat sandwich body with a structure similar to sandwich. Due to the difference in refractive index between the substrate and the oxide deposited on its surface and each oxide, when the light shines on the surface of the pearlescent pigment, the incident light will be refracted and reflected at the interface of each layer of the pearlescent pigment, and the color of the pearlescent pigment that people see is the result of the superposition of light after multiple refractions and reflections of the light, that is, the interference phenomenon of light.

4. Test and Adjust Always perform a patch test to ensure your skin reacts positively to the new formulation. Adjust the mica content based on your personal preference.

Another significant advantage of pearl powder is its eco-friendly aspect. Unlike synthetic additives, pearl powder is derived from a natural source, making it a more sustainable choice for environmentally conscious consumers. As the automotive industry increasingly focuses on reducing its ecological footprint, incorporating natural materials like pearl powder into car paint formulations aligns with the broader goal of sustainable manufacturing. This shift not only benefits the environment but also resonates with consumers looking for sustainable options in their purchasing decisions.
