Colorants Suitable for Mascara Formulations

The colorants commonly used in mascara include:

• Iron Oxides: These provide black, brown, yellow, and red shades. They are widely used in makeup for their stability and color intensity.
• Chromium Oxide Green: This provides green color. It is approved for use on the face and around the eyes.
• Ultramarine Blue: This provides blue color. It is also approved for use on the face and around the eyes.
• Manganese Violet: This provides purple color. It is used in makeup products.

These colorants are typically dispersed in the mascara formula.

Regarding a specific formula with percentages, I cannot provide that information. Formulations are complex and depend on various factors to achieve the desired performance (like consistency, wear, and application).

Here is the information about the colorants:

• Iron Oxides: Available in various forms (Yellow, Red, Black), including treated versions like EasyMix™ for better dispersion and feel. They are dispersed in oil or silicone and used at rates typically between 1-20%.
• Chromium Oxide Green (CI 77288): A green powder dispersed in oil, silicone, starch, and water. Used in makeup products at 0.1-1%. Approved for use on nails, facial skin, and around the eyes, but not around the lips.
• Ultramarine Blue (CI 77007): A blue powder dispersed in oil, silicone, starch, and water. Used in makeup products at 0.1-1%.
• Manganese Violet (CI 77742): A purple powder dispersed in oils, silicones, and powders. Cannot be used in water-based formulas. Used in makeup products at 0.1-1%.

These colorants are pigments, meaning they provide color by being dispersed in the product rather than dissolving.
