Epoxy pearl pigments are often combined with other cosmetic ingredients to create long-lasting formulas that provide a multi-dimensional effect when applied to the skin. The versatility of these pigments allows makeup artists to experiment with different looks and styles, from subtle highlights to bold, dramatic finishes.

X represents large interlayer cations, such as K+, Na+, Ca2+, Ba2+, Rb+, Cs+, etc. Y represents octahedral cations, such as Al3+, Fe2+, Mg2+, Cr3+, Ti4+, Fe3+, etc. Z is mainly Si4+ and Al3+; The ideal ratio of the additional anion (OH)- to (O)2- is 2:10, and (OH)- can be replaced by F- and Cl-. Most mica contain 4% to 5% water. Therefore, although they may be called mica, the chemical composition of different mica may be very different, for the purpose of research, we collectively refer to the minerals with this type of characteristics as mica group minerals.  

Mica has a wide range of uses, in ancient China, it is often used to do traditional Chinese medicine, the ancients even think that taking mica: a year to remove all diseases (heavy metal poisoning), three years of long service, husband into a boy (body scrap), Zhongshan uncle Qing suit, over time can become a cloud (soul ascension). However, in the era without glass, the transparency of mica makes it a better decorative material, for example, we are familiar with the mica screen candle shadow deep, the river gradually falling Xiaoxing sink. Mica screen is low, tassel tent is small and mica calf car.

Sustainability Concerns and Ethical Sourcing of Mica Pigments

For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.

When it comes to cosmetics, the safety of mica powder largely depends on its sourcing and processing. Mica is generally considered safe for topical use, especially when derived from reputable suppliers who adhere to industry safety standards. However, concerns have arisen regarding the ethical implications of mica mining, which can impact its safety profile. Unregulated mining practices, often in developing countries, can lead to the inclusion of contaminants in mica powder, such as heavy metals.

Bakers and confectioners are increasingly adopting this trend, as gold mica can elevate the presentation of their creations. Whether dusting a cake or creating intricate designs on pastries, gold mica powder adds a visually appealing element that is both attractive and appetizing.

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.
