Iron oxides in pigmetns

Iron Oxide in the Cosmetic Industry The assertion that there have been “revolutionary transformations” in producing iron oxides for semi-permanent makeup is more of a marketing stance than a scientific breakthrough. Iron oxides used in cosmetics are chemically identical to those used in other industrial applications. There isn't a unique "cosmetic grade" iron oxide; the same fundamental compounds are utilized across various industries. The key differentiator for cosmetics is the stringent purity, particle size, and safety requirement. Quality and Compliance of Iron Oxides Pigment producers must source iron oxides that meet specific criteria: sufficient quality, appropriately small and uniform particle...
