This product is made from ultra-high purity iron oxide raw materials through multiple purification processes, strictly controlling heavy metal and microbial content, complying with FDA and EU food contact material standards, and will not cause harm to human health. Its moderate particle size ensures uniform dispersion in food and pharmaceutical systems, avoiding agglomeration, and it has excellent chemical stability, which will not react with food and pharmaceutical ingredients. It solves the pain point that ordinary iron oxide black cannot meet the compliance requirements of the food and pharmaceutical industry, providing a safe and reliable coloring solution for food and pharmaceutical products.
This food and pharmaceutical grade iron oxide black has a purity of not less than 99.8%, an average particle size of 1-3μm, a pH value range of 6.0-7.5, a moisture content of ≤0.2%, with arsenic content ≤1ppm and lead content ≤3ppm. Its microbial limit complies with USP 40 standards, and it holds FDA 21 CFR 173.310 and EU 1935/2004 certifications. It is insoluble in water and organic solvents, and has good dispersibility in food grade coatings and pharmaceutical preparations. It is packaged in 5kg moisture-proof cartons, stored in a cool and dry place, with a shelf life of 3 years.
It is mainly used in food packaging coatings, pharmaceutical capsule shell coloring, medical device coatings, food contact plastic product coloring and other fields. It is suitable for food processing equipment, pharmaceutical packaging, medical devices and other scenarios requiring compliant coloring, providing safe and compliant black appearance for products, and meeting the strict requirements of the food and pharmaceutical industry for product safety and compliance.
