Iron oxides are artificial ingredients that function as colorants in makeup products and personal maintenance systems. Iron oxides are inorganic substances of iron and air that have been used as coloring agents in makeup products since the early 1900s. Iron oxides occur naturally, for example, corrosion is a kind of iron oxide. Red iron oxide can be produced from the nutrient hematite normally; yellow iron oxides come from limonites such as others, siennas, and numbers; dark iron oxide is from the nutrient magnetite.
However, the iron oxides used in cosmetics are artificial. There are a total of 16 different iron oxides used in cosmetics. In addition to use in makeup products, iron oxides can be found in paints, coatings, and shaded concretes. Iron oxides are closely regulated by the United States Food and Drug Administration (FDA). In makeup products and personal care products, iron oxides function as colorants. They may be the primary pigments used for complementing skin shades in foundations, powders, concealers, and make up for the facial skin other. Iron oxides can also be found in eye shadows, blushes, powders, lipstick, and mineral makeup.
Iron oxides can be purchased in three basic shades: black (CI 77499), yellowish (CI 77492), and red (CI 77491). There’s also various tones of dark brown iron oxides, but they are just mixtures of the three previously mentioned colors. Yellow iron oxide (CI 77492) gets the chemical formula Fe2O3•H2O. When yellowish iron oxide is warmed to about 800°C in the absence or limited way …
