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.

2. Crushing and Grinding Once the mica ore is extracted, it undergoes crushing and grinding to reduce the size of the particles. This step is crucial in preparing mica for further processing, allowing for the separation of mica from the surrounding minerals.

Mica powder is generally considered safe for use in cosmetic applications, including lip products. The Cosmetic Ingredient Review (CIR) has assessed the safety of mica and determined that it is safe for use in cosmetics when properly processed. However, there are a few essential points to consider

1. Natural Shine and Radiance One of the most significant advantages of gold mica powder is its ability to create a beautiful shimmer without being overly glittery. This feature is especially important in makeup products such as foundations, highlighters, and bronzers, where a subtle glow is often desired. Gold mica provides a soft luminosity that can enhance the skin's appearance, giving it a fresh and youthful look.

The versatility of matte mica powder extends beyond traditional glosses. Formulators can experiment with different finishes and textures, creating hybrid products such as matte lip creams or lip stains that provide the best of both worlds. Additionally, matte mica powders can be combined with other ingredients, such as essential oils or herbal extracts, to incorporate added benefits, including soothing properties or sun protection.

Cosmetics Industry: In some high-end cosmetics, resin mica powder is used to add a subtle shimmer to products like eyeshadows and highlighters.
