Is Pigment Red 101 FDA compliant for use in food contact packaging and cosmetic applications?
The Chemical Profile of Pigment Red 101 Inorganic Stability: Pigment Red 101, chemically known as synthetic iron oxide ($Fe_2O_3$), is one of the most stable inorganic pigments available. Its resistance to UV light, heat, and chemical migration makes it a primary choice for sensitive applications. Natural vs. Synthetic: While iron oxides exist in nature, only high-purity synthetic versions are ty...

Is Iron Oxide Powder Safe? What You Need to Know
Iron Oxide Powder Is Generally Safe — But Context Matters Iron oxide powder is considered safe for most everyday uses, including cosmetics, food coloring, and industrial applications. Regulatory bodies such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have approved specific forms of iron oxide as safe for use in food and personal care products. Howev...

How does the purity of black iron oxide pigment affect its UV stability and color consistency?
The Chemical Relationship Between Purity and UV Stability Resistance to Photo-Oxidation: High-purity black iron oxide pigment is inherently UV-stable due to its inorganic crystalline structure. Unlike organic dyes, it does not break down under solar radiation. However, high purity (measured by $Fe_3O_4$ content) ensures the absence of soluble salts that can cause efflorescence, which often mimics...
