The mica variety that does not contain iron is colorless in flakes, and the higher the iron content, the darker the color, and the more polychromatic and absorbable it is. According to the different chemical composition and optical characteristics, mica group minerals can be divided into Muscovite subgroup, biotite-phlogopite subgroup and lemica subgroup. The common mica are biotite, phlogopite, Muscovite and so on.

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.

In addition to electronics, mica is also a critical ingredient in the cosmetics industry. It is commonly found in makeup products, such as eyeshadows, highlighters, and foundation, where it serves multiple purposes. Mica provides a shimmering effect, enhancing the appearance of the skin and creating a luminous finish. Moreover, its absorbent properties help to control oil, making it a popular choice for products designed for oily or combination skin types. As consumers become more conscious of the ingredients in their cosmetics, the demand for natural and mineral-based products has surged, further boosting the mica market.

Natural mica powder and synthetic mica powder have differences in production methods, heat resistance and color transparency. As the name suggests, natural mica powder is made from natural mica ore after processing, retaining the original characteristics and composition of the ore. Its main components are SiO2 (about 49%) and Al2O3 (about 30%), while also containing K2O+Na2O (9%-11%) and so on. The synthetic mica powder (such as fluoroglogopicite powder), is the use of a variety of raw materials through high temperature reaction and other chemical methods synthetic, its composition and characteristics can be adjusted and optimized according to the need, the chemical formula is KMg3(AlSi3O10)F2, belongs to the monoclinic crystal system, is a typical layered silicate, relatively single and pure composition. The heat resistance of natural mica powder is generally 500-600℃, and some types, such as phlogopite, can reach 800℃. The heat resistance of synthetic mica powder is more excellent, and it can withstand high temperatures above 1200℃, and the melting point or crystallization temperature is about 1375±5. The transparency of natural mica powder is relatively low, and the color is diverse, including black, yellow, white, gray, green, brown and other colors, and may vary due to different ore types and processing methods. The color of synthetic mica powder is relatively single, usually colorless transparent or white, high whiteness, good optical performance, and high transmittance from ultraviolet to infrared band.

How to Use

While mica glitter is generally safe for candle making, it is crucial to choose high-quality, cosmetic-grade mica to avoid any harmful additives. Candle makers should ensure that the mica they use is specifically labeled for use with wax to prevent burning issues and ensure the glitter holds up in the heat. Additionally, it’s important to note that while mica glitter adds beauty, excessive amounts might affect the candle’s burn quality, so moderation is key.

Safety Considerations

What is Mica Powder?

As cosmetic formulations become more sophisticated, innovations in pearlescent pigments are emerging. Brands are experimenting with novel application methods and combinations with other materials to achieve unique textures and finishes. The rise of clean beauty products has encouraged manufacturers to develop environmentally friendly pearlescent options, ensuring that consumers can enjoy luxurious cosmetics without compromising their values.

Synthetic mica, produced in controlled environments, offers a sustainable option that reduces the environmental impact of traditional mining. However, despite its benefits, synthetic mica still accounts for a small percentage of the market, with natural mica remaining the preferred choice for many cosmetic formulations due to its superior quality and reflective properties.

Titanium dioxide, for example, creates a more opaque and pearlescent effect, while iron oxide coatings can produce a range of warm, earthy tones. By adjusting the types of coatings applied to the mica flakes, manufacturers can create pigments in a wide array of colors, from soft pastels to vibrant metallics. These enhanced mica pigments are often referred to as “synthetic mica” or “coated mica,” and they are widely used in cosmetic formulations for their ability to provide a rich, intense color payoff along with a stunning visual effect.
