Yellow Undertone

Slightly more brown then CG100.

Iron Oxides are the most widely used of the Inorganic Pigments. There are 3 basic colors - Red, Black and Yellow Oxides. From these 3 oxides and the addition of Titanium Dioxide, you can achieve any shade of brown. If you are trying to create a skin tone foundation, blush, bronzer or other product this is where you start. Oxides are stable under normal pH ranges and 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.

This Red Iron Oxide (CG170) is both water and oil dispersible. It must be mixed using a shearing force to get it to blend. (Use a stick blender for a complete mix.)

For dry applications, simply mix with the base clay or powder or other dry medium.

This oxide can be used for eye makeup, lotions, creams and salts, scrubs, face powders, foundations, blushers, and cosmetics used in the area of the eye such as mascaras, eyeshadow, liners and to color or swirl soaps.
