Understanding the Optics of Optique Pearl Red
Creating Color Through Light Interference
Optique Pearl Red produces its signature effect not from traditional absorption pigments, but from the physics of light interference. This pigment is engineered by depositing a highly controlled, thin layer of Titanium Dioxide (CI 77891) onto a natural mica platelet. When white light strikes this coated platelet, it separates into its component parts, producing a dual color effect—one color is reflected (red), and its complementary color is transmitted. The result is a luminous, iridescent effect that shifts with the viewing angle.
Formulation Benefits of a Classic Pearl Structure
The 10–60 μm particle size range provides a classic satin to pearl finish that is highly versatile. It is large enough to create visible luster but small enough to ensure a smooth, non-gritty texture that is suitable for all applications, including lip products. The natural mica substrate offers a combination of transparency, luster, and slip, making it easy to incorporate into various cosmetic systems, from pressed powders to liquid emulsions.
