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.

Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:

Natural mica powder and synthetic mica powder also have great differences in electrical insulation, mechanical properties, chemical stability, application range and cost. Natural mica powder has good electrical insulation, but the volume resistivity is lower than that of synthetic mica. Synthetic mica powder has better electrical insulation properties, high volume resistivity and stable dielectric constant, and is suitable for high performance electrical insulation materials. The hardness of natural mica powder is relatively low (2-3), and it has good elasticity and peeling property. The hardness of synthetic mica powder is higher (between 3 and 4), and the tensile strength and compressive strength are better than that of natural mica powder. Natural mica powder is stable in acid-base solution, but it is easy to decompose at high temperature. Synthetic mica powder is stable to acid and base at room temperature, but will be slowly corroded by sulfuric acid above 300℃. Better thermal stability, not easy to release gas. Natural mica powder is widely used in electrical appliances, welding rods, rubber, plastics, paper making, paint and other fields. Synthetic mica powder is mainly used in high-end electrical insulation materials, aviation, aerospace, national defense industry and other high-tech fields. Because synthetic mica powder needs to be produced through complex chemical processes, its production cost is usually higher than that of natural mica powder. Therefore, in the market, the price of synthetic mica powder is often higher than that of natural mica powder. However, with the continuous progress of production technology and the gradual emergence of scale effects, the price of synthetic mica powder is expected to gradually decrease.

Authoritativeness in the mica supply chain is another crucial consideration. Reputable suppliers often possess certifications and endorsements from recognized industry bodies. These credentials serve as evidence of adherence to international standards in quality, environmental management, and occupational health and safety. Working with authoritative suppliers ensures not only product quality but also ethical considerations such as sustainable mining practices and social responsibility. Paying attention to a supplier's reputation within trade associations and peer reviews can provide additional insights into their standing and reliability in the market.

1. Thermal Stability One of the most notable attributes of mica is its ability to withstand high temperatures without degradation. This property is particularly advantageous in automotive applications, as components are often subjected to extreme conditions.

It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.

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.

The Appeal of Using Natural Mica

White mica is utilized in a variety of sectors due to its beneficial properties. In the cosmetic industry, it is a key ingredient in makeup products such as eyeshadows, foundations, and highlighters. Its reflective qualities provide a shimmering effect that enhances the appearance of skin, making it a favorite among makeup enthusiasts. Additionally, as an inert filler, it contributes to the texture and smoothness of many beauty products without causing irritation.

Layer upon layer of mica

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 the beauty industry continues to evolve, the shift toward synthetic mica underscores a broader movement towards sustainability and ethical practices. By embracing synthetic alternatives, brands can provide consumers with products that not only enhance beauty but also uphold social responsibility. As awareness of the impacts of natural mica mining grows, it is clear that synthetic mica is poised to become a staple ingredient in the makeup world, promoting a brighter and more sustainable future for cosmetics. With ongoing innovations and an increasing focus on ethical sourcing, the future of makeup is indeed sparkling with potential.

Trustworthiness is a cornerstone for any successful manufacturer-client relationship. Top mica manufacturers maintain transparent supply chains, providing full disclosure about sourcing, processing, and delivery. Ethical sourcing practices, including the non-exploitation of labor and environmentally sustainable extraction processes, further enhance their reputation. Reliable manufacturers offer robust quality assurance protocols, backed by certifications from prestigious international bodies. Their commitment to delivering consistent quality not only earns clients' trust but also fosters long-term partnerships.
