Which of the following is a natural coloring sometimes used in lip colors?

Lead
Iron oxide
Synthetic dyes
Coal tar

The correct answer is: Iron oxide

Iron oxide is recognized as a natural coloring agent often utilized in lip colors. This mineral-based pigment is favored in the cosmetic industry due to its stability, safety, and ability to provide a wide range of colors, including reds, browns, and yellows, while adhering to strict regulatory standards. Because of its natural origin and non-toxic profile, iron oxide is particularly popular for formulations designed for sensitive areas such as the lips. In contrast, lead is a toxic heavy metal and should never be used as a coloring agent in cosmetics due to serious health risks. Synthetic dyes and coal tar, although sometimes included in cosmetic formulations, do not fall under the category of natural coloring agents and may carry other safety and environmental concerns. Thus, iron oxide stands out as the appropriate and safe choice for natural coloring in lip products.
