Performance & Formulation Insights for Gemini RC-18
The Science of a Dramatic Color Shift
Gemini RC-18 achieves its signature red-to-cyan color travel through a multi-layer coating process. A natural mica platelet is first coated with iron oxides to create the warm red base, followed by a precisely controlled silica layer. The silica coating generates light interference, producing secondary cyan and green reflections that interact with the iron oxide absorption color to create a dramatic, complex chromatic effect.
This engineered interplay between absorption and interference cannot be replicated by simple pigment blends, enabling richer color depth, a broader viewing angle, and a more dynamic shift in finished formulas.
Leveraging Particle Size for Impact
With a particle size range of 20–80 μm, Gemini RC-18 delivers a brilliant, sparkling finish that reads bolder and more dimensional than finer-milled pigments. The larger platelet size enhances visual impact in statement products such as nail lacquers, lip toppers, and high-chroma eyeshadows.
In formulation, the pigment disperses readily and shows excellent stability in medium-to-high viscosity systems. For liquid and gel formats, consider a suitable suspending agent to maintain uniform distribution over shelf life.
