Silver
What is Silver?
Silver, chemical symbol Ag and atomic number 47, is a precious transition metal known for its luster and malleability. In cosmetics, it appears as a fine, insoluble powder designated CI 77820, mainly in makeup categories like eyeshadows, lip products, and nail polishes. It functions by dispersing light to deliver a reflective metallic sheen, enhancing visual appeal and ensuring batch-to-batch color uniformity without altering product texture or stability. Incorporated in trace amounts, it adheres to surfaces for durable effects during wear. Unlike soluble forms, cosmetic-grade silver remains inert on skin, prioritizing aesthetic enhancement over functional skin interaction. Safety assessments confirm its suitability for topical colorant use, with minimal bioavailability due to its particulate nature.
