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 to obtain oxygen, it decomposes to form red iron oxide (Fe2O3).
This process is recognized as calcination. Black iron oxide (Fe3O4) is a mixture of ferric and ferrous oxides. Iron oxides are opaque and have excellent light stability, however, yellowish and black iron oxides are delicate to high temps. Iron oxides are also resistant to moisture, so they won’t easily bleed or smear. Iron oxides have excellent “stamina”, which means that the product shall last for a long time without needing to be reapplied. The Cosmetic Ingredient Review (CIR) Expert Panel has deferred evaluation of iron oxides because the safety has been assessed by FDA.

All color additives used in foods, drugs, and makeup products in the United States must be approved by FDA and are shown in the Code of Federal Regulations. The FDA only approves colors after a comprehensive review of all security data and publication of the basis for its approval in the Federal Register.
Iron oxides are considered to be safe as used in makeup products and personal care products because they’re non-toxic and non-allergenic. Iron oxides are well tolerated by those with sensitive skin even. Though iron oxides are synthetic ingredients Even, they are still often found in products that are marketed as natural or organic. It is because the synthetic versions of iron oxides are safer than the natural versions actually, which often contain impurities. For instance, oxides formed in an all natural, uncontrolled setting are contaminated with heavy metals. This demonstrates that just because an ingredient is natural will not always mean it is safe.
” If a product says it’s “natural” on the label, will that mean it doesn’t contain any artificial chemicals whatsoever? So long as it’s a chemical, which means it’s toxic and bad for you, right? Did you know that fruits and vegetables are full of occurring toxins naturally? It’s the dose that makes them toxic. An excessive amount of a very important thing is not so good for us.
We’ve been eating fruits and vegetables and using elements of them in skin care products for thousands of years. Many of them contain naturally-occurring toxins and chemicals. For example, peach pits contain cyanide. Oranges have methanol in them. Almonds, cassava root base, bamboo shoots, apricot and plum stones, for instance, all contain chemical compounds that could lead to the forming of hydrogen cyanide.
Our bodies are made of chemicals, and we consume to replenish those chemicals with chemicals from food. Synthetic chemicals similar to natural chemicals work the same and can be utilized in the same way exactly. In fact, get rid of the labels, and you would not be able to tell the difference between your two.
