Red Oxide Technical Specifications

Applications:
Colors used in the Cosmetic Industry can be grouped into two categories: FDA Certified Organics and Inorganic Pigments.
Inorganic pigments are controlled by the Food and Drug Administration. Prior to 1960, the only requirements for inorganic pigments were that they meet heavy metal concentrations as specified by the FDA. A listing of these color additives and requirements can be found in the Code of Federal Regulations 21, Part 73. All of our products are tested and certified to meet these standards. Inorganic pigments are primarily used in pigmented face powders, foundations, blushers, nail lacquers and cosmetics used in the area of the eye such as mascaras, eyeshadows, liners, etc.
Iron Oxides
By far, the largest single volume of inorganic pigments sold are iron oxides. There are three basic shades - black, red and yellow. By using these shades in combination with titanium dioxide, all shades of browns and skin tones can be matched. We have also introduced a pure, unblended brown iron oxide. Iron oxides are stable under most conditions. They have excellent light stability and are stable under normal ph ranges. One caution in using yellow or black oxide is to avoid prolonged exposure to high temperatures (300 degrees F). Yellow has a tendency to drift to the red side and black will drift to the brown side under heat conditions. The shade characteristic of an iron oxide is known as an undertone. The red and black oxides may have either a blue or yellow undertone. By tinting with talc or titanium dioxide, a formulator can easily determine the undertone of an iron oxide.
