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.

In the world of cosmetics, safety and quality are paramount. One ingredient that has gained significant attention in recent years is mica powder, especially in products intended for lip care and makeup. This article explores what lip-safe mica powder is, its benefits, any potential risks, and how to ensure you are using it safely in your cosmetic formulations.

Mica’s reflective properties are highly sought after for creating makeup products that offer a natural glow, smooth texture, and dimensional appearance. This has led to its widespread use in high-end cosmetic lines as well as affordable drugstore brands. The trend toward glowing or lit-from-within makeup has fueled the demand for mica-based products, cementing its place in modern cosmetics.

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.

- Seal the Finish Once your painted surface has dried, consider applying a clear sealant to protect the mica-enhanced finish and enhance its durability.

นอกจากการใช้งานที่ได้กล่าวมาแล้ว ผงมิก้ายังมีบทบาทในอุตสาหกรรมอื่น ๆ เช่น การผลิตเส้นใยและวัสดุที่มีความยืดหยุ่น เช่น สายไฟ เนื่องจากมิก้าเป็นวัสดุที่ไม่สามารถนำไฟฟ้าได้ จึงช่วยเพิ่มคุณสมบัติการเป็นฉนวนได้เป็นอย่างดี
