In 2022, Lingshou Huajing Mica Co., Ltd. launched cosmetic grade mica powder. The flake structure of mica powder can lock the water on the surface of the skin, forming a protective film to effectively prevent water loss. Its unique gloss and reflection effect add natural and charming luster to the skin, and mica powder also has a certain sunscreen effect. To a certain extent, it can reduce the damage of ultraviolet rays on the skin, protect the skin from the external environment, and prevent sunburn.
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.
2. Creating Effects Mica powder can be employed to achieve specific effects in resin art. Artists can manipulate the mixture to create depth, gradient transitions, or a marbled look. For instance, mixing different colors of mica powder can produce stunning effects reminiscent of natural stone or seashells, providing a sophisticated touch to jewelry, coasters, and tabletops.

The formulation of cosmetic pigment powders is a sophisticated process. Manufacturers blend different pigment types to produce a spectrum of shades that cater to diverse skin tones and preferences. Additionally, the quality of the powder is dictated by particle size and texture, which affects how well it adheres to the skin and blends during application.
In short, there are significant differences between natural mica powder and synthetic mica powder in production methods, color and appearance, performance characteristics, application fields, and price and cost. Synthetic mica powder is superior to natural mica powder in terms of high temperature resistance, transparency, electrical insulation, stability and mechanical properties, while natural mica powder has more advantages in resource acquisition, cost and color. When choosing which type of mica powder to use, you can consider the high temperature resistance of the required material, electrical insulation performance, transparency and color requirements, evaluate the mechanical strength and hardness of the required material, consider chemical stability and other different application scenarios and technical requirements to make a reasonable choice.
Later, with the development of science and technology, people gradually realized that mica minerals have high insulation, high temperature resistance, strong acid and alkali resistance, and mica also began to enter building materials, fire, plastics, paper, rubber, pearlite pigments and other industries. These are mainly Muscovite and phlogopite.
As industrial applications for mica continue to expand, the demand for processed mica is anticipated to grow. Advances in processing technology may enhance the efficiency and effectiveness of mica processing plants, leading to purer products and reduced environmental impacts. Furthermore, increasing consumer awareness about ethical sourcing is likely to pressure mica suppliers and processors to adopt sustainable practices.
