Mica is a naturally occurring silicate mineral that is prized for its shimmering and reflective properties. Traditionally used in cosmetics to create luminous finishes, mica has become a staple in formulations ranging from eyeshadows and highlighters to nail polishes and body lotions. However, conventional mica mining practices have raised significant ethical and environmental concerns. Many mica mines, particularly in developing countries, have been linked to serious human rights violations, including child labor and unsafe working conditions. Additionally, traditional mining can lead to environmental degradation, affecting local ecosystems and communities.

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.
