Used in cosmetics and personal care products as a pearlescent pigment to provide shimmer and glow. Commonly found in foundations, eyeshadows, lipsticks, and nail polishes due to its ability to reflect light and enhance visual appeal. Also utilized in paints, coatings, and plastics to improve surface finish and provide a metallic or glossy effect. Its layered structure offers barrier properties, making it useful in formulations requiring moisture resistance or improved durability. Stable under high temperatures and UV exposure, it is suitable for both decorative and functional applications.
