Iron oxides are produced synthetically and consist essentially of anhydrous and/or hydrated iron oxides. The range of hues includes yellows, reds, browns and blacks.They are oxidant chemicals. Food quality iron oxides are primarily distinguished from technical grades by the comparatively low levels of contamination by other metals. This is achieved by the selection and control of the source of iron and/or by the extent of chemical purification during the manufacturing process. Iron oxides have been used to color confectionery, fillings and decorations for pastry products, cheese products, fish paste, pet foods, cosmetics and pharmaceutical products. We Wuhan Ruisunny Chemical Co., Ltd has been focusing on trading of such chemicals as Calcium Hypochlorite, Trichloroisocyanuric Acid, Ammonium Bicarbonate, Sodium Hydroxide, Hydrogen Peroxide and Silane etc. since 2007. We hereby have following details for the product as:
