Iron Oxide Pigments / Synthetic Iron Oxide. Synthetic Iron Oxides have become increasingly important due to their pure hue, consistent properties, and tinting strength. Single-component forms are mainly produced with red, yellow, orange and black colours. Their composition corresponds to that of minerals hematite, goethite, lepidocrocite, and magnetite. Brown pigments usually consist of mixtures of red and/or yellow and/or black iron oxides.
No. Due to high levels of toxic contaminants such as arsenic, mercury, lead and selenium found in naturally occurring iron oxides, the iron oxides used in cosmetics and soap have been manufactured in labs since the 1970âs. The purpose of this was to make these colors safer by manufacturing a product with fewer toxins.
