Dehydrated mica is widely used in the cosmetics and personal care industry due to its excellent reflective and textural properties. It serves as a base in products like eyeshadows, blushes, foundations, and lipsticks, providing a smooth, silky feel and enhancing the product’s spreadability. Its plate-like structure allows for uniform pigment dispersion and contributes to long-lasting wear.

In industrial applications, dehydrated mica acts as a reinforcing agent in paints, plastics, and rubber, improving thermal stability, mechanical strength, and resistance to weathering and chemicals. It is also used in drilling fluids for oil and gas exploration, where it helps control fluid loss and stabilize boreholes.

Additionally, it finds use in the electronics industry as an insulating material in high-temperature and high-voltage applications, thanks to its dielectric strength and thermal resistance. Its inert nature makes it suitable for coatings and encapsulation materials where stability is critical.
