Understanding Yellow Iron Oxide: A Foundation of Earthy, Stable Color Yellow Iron Oxide is an inorganic compound, primarily hydrated ferric oxide (FeO(OH) or Fe2O3·H2O). It is a widespread mineral and can also be synthetically produced for enhanced purity, consistency, and specific color shades. Unlike dyes, it is insoluble in water and functions by dispersing evenly throughout the medium to impart color and opacity. It is valued for its:

• Exceptional Opacity: Provides excellent hiding power, making it highly effective for solid, deep yellow coverage.
• Superior Lightfastness: Highly resistant to fading when exposed to UV light, ensuring long-lasting color integrity.
• Chemical and Weather Resistance: Maintains its color and structural integrity under harsh environmental conditions and chemical exposure.
• Thermal Stability: Withstands moderate temperatures without degradation. At higher temperatures (typically above 180°C), it may dehydrate and transform into red iron oxide.

FDA-Approved for Cosmetics & External Drugs in the US Our Yellow Iron Oxide CI 77492 is fully compliant with U.S. regulatory standards, being FDA-approved for several key applications:

• Cosmetics: Approved as a color additive for all cosmetics, including those applied around the eye (21 CFR § 73.2250). It’s a staple in foundations, powders, eyeshadows, and blushes.
• Externally Applied Drugs: Approved for coloring drugs applied externally (21 CFR § 73.1299). These approvals certify its safety and suitability for direct human contact in beauty and topical pharmaceutical products, confirming it is exempt from certification.
• Limited Food Use: While not broadly approved as a direct color additive for human food in the US, specific grades of synthetic iron oxide yellow are approved for use in coloring ingested drugs (21 CFR § 73.1200) and in pet food (21 CFR § 73.299). This makes it a trusted choice for formulators seeking compliant and high-performance pigments for beauty products, pharmaceuticals, and broader industrial uses.

Versatile Applications Across Industries:

• Cosmetics & Personal Care: A leading choice for foundations, powders, blushes, eyeshadows, lip products, and soaps, providing intense, natural-looking yellow hues and opacity.
• Paints & Coatings: Used extensively in architectural paints, industrial coatings, automotive finishes, and protective coatings for its deep color, durability, and UV resistance.
• Plastics: Incorporated into various plastic products, including packaging, automotive parts, and consumer goods, to achieve stable yellow coloration.
• Construction Materials: Employed to color concrete, mortar, paving stones, bricks, and roofing tiles, offering durable and attractive yellow shades that resist fading.
• Inks & Toners: Provides strong yellow pigmentation for printing inks, art supplies, and specialized toners.
• Artistic & Craft Applications: Ideal for pigments in art paints, ceramics, and various craft projects.

Quality and Safety Assurance: Our Yellow Iron Oxide CI 77492 Powder is manufactured under strict quality control to ensure high purity and consistent performance. For cosmetic and drug applications, it meets the rigorous standards set by regulatory bodies. While inorganic pigments are generally very stable, proper handling is always recommended to ensure safety and product integrity. Store in a cool, dry place to prevent clumping and maintain its powder form. As an insoluble pigment, it should be thoroughly dispersed, not dissolved, into your desired medium for optimal color development. Always refer to the product’s Safety Data Sheet (SDS) for comprehensive handling guidelines.

FAQs:

Q: Is Yellow Iron Oxide CI 77492 approved for use in cosmetics and external drugs in the US? A: Yes, cosmetic-grade Yellow Iron Oxide (CI 77492) is FDA-approved for use in all cosmetics, including around the eye, and for external drug applications in the United States. It is listed as a safe color additive in the U.S. Code of Federal Regulations (21 CFR § 73.2250 and § 73.1299) and is exempt from certification.

Q: Can Yellow Iron Oxide be used as a color additive in human food? A: Yellow Iron Oxide (CI 77492) is not generally approved as a direct color additive for human food in the US. While specific synthetic iron oxide yellow is approved for coloring ingested drugs and pet food, its use as a general colorant for human food is not permitted under current FDA regulations for this pigment.

Q: What are the key properties of Yellow Iron Oxide as an inorganic pigment? A: Yellow Iron Oxide is known for its deep, earthy yellow to golden color, exceptional opacity (hiding power), superior lightfastness (resistance to fading), and excellent weather and chemical stability. These properties ensure the color remains vibrant and consistent over time, even in harsh conditions, and that it is non-migrating.

Q: What are the primary industrial applications for Yellow Iron Oxide CI 77492? A: Beyond cosmetics and external drugs, Yellow Iron Oxide CI 77492 is extensively used in the paints and coatings industry for its deep color and durability, in plastics for consistent yellow coloration, and in construction materials like concrete, mortar, and bricks for aesthetic and weather-resistant purposes. It’s also found in inks and various art applications.

Q: How should Yellow Iron Oxide powder be stored and handled? A: Yellow Iron Oxide powder should be stored in a tightly sealed container in a cool, dry place, away from direct sunlight and moisture, to prevent clumping and maintain its integrity. When handling, it’s advisable to use appropriate personal protective equipment (PPE), such as a dust mask, gloves, and eye protection, to minimize inhalation of fine particles and direct contact. Since it’s insoluble, it should always be thoroughly dispersed, not dissolved, into your product formulation.
