رنگ اکسید آهن قرمز

Iron Oxide Red is an inorganic pigment widely used in pharmaceuticals, cosmetics, and food products to impart a red color. Chemically known as ferric oxide (Fe₂O₃), it is valued for its stability, non-toxicity, and resistance to heat, light, and chemical degradation.

🏭⚗️ Production
Iron Oxide Red is produced either by natural extraction from hematite ore or synthetically through controlled oxidation of ferrous salts such as ferrous sulfate. The process may involve precipitation, thermal treatment, filtration, and milling to achieve fine, uniform particles with consistent color intensity. Industrial production ensures high purity, uniform particle size, and reproducible pigmentation for pharmaceutical and cosmetic applications.

🔬 Properties
Iron Oxide Red appears as a fine, red powder with excellent chemical and thermal stability. It is insoluble in water and most organic solvents, chemically inert, and non-reactive with other excipients. The pigment maintains its color under exposure to light, heat, and acidic conditions, making it ideal for coated tablets, capsules, and cosmetic formulations.

🧪 Applications
In pharmaceuticals, Iron Oxide Red is used to color tablets, capsules, and coated formulations, providing consistent red hues without affecting drug stability. In cosmetics, it is applied in foundations, lipsticks, and blushes. In food products and nutraceuticals, it serves as a colorant where a natural or stable red pigment is needed. Its inertness also makes it suitable for laboratory and research applications.

⚠️ Safety
Iron Oxide Red is generally recognized as safe for pharmaceutical, cosmetic, and food use. It is non-toxic, non-irritant, and stable under normal handling conditions. Fine powders should be handled carefully to avoid inhalation, and personal protective equipment such as gloves and masks is recommended in industrial or laboratory settings. The pigment should be stored in a cool, dry place away from strong acids and reducing agents to maintain quality.
