CI 77491, CI 77492, CI 77499

CI 77491, CI 77492, and CI 77499 are synthetic iron oxides that provide yellow, red, and black pigmentation respectively in cosmetic formulations. These inorganic pigments are chemically identical to naturally occurring iron oxides but are manufactured under controlled conditions to ensure purity and consistent color performance. Formulators favor these iron oxides because they offer excellent color stability, are non-bleeding, provide broad spectrum UV protection as a secondary benefit, and are suitable for use around the sensitive eye area unlike many organic colorants.
