Copper Powder
What is Copper Powder?
Copper Powder refers to micronized particles of elemental copper metal, obtained by refining copper ore through mining and metallurgical processes. In cosmetics, it belongs to the category of inorganic pigments and is mainly used in decorative makeup items such as eyeshadows, highlighters, face powders, and nail polishes. It functions by dispersing light to produce a reflective metallic sheen and a distinctive reddish-brown color, enabling formulators to create vibrant, long-lasting visual effects. The insoluble nature of the powder ensures it adheres to skin surfaces without dissolving, contributing to product stability and even application across batches. Its particle size is controlled to minimize settling and optimize spreadability in formulations.
