Performance & Formulation Insights for Gemini CS-18

Advanced Color Travel with Silica Encapsulation

Gemini CS-18 achieves its dramatic copper color travel effect through a sophisticated composition of natural mica and iron oxides treated with silica. The silica layer enhances stability, provides a uniquely smooth feel, and optimizes light refraction to produce a more pronounced, vivid color shift as the viewing angle changes.

Optimized for High Coverage & Smooth Feel

The inclusion of CI 77491 (Iron Oxide Red) delivers high coverage and intense payoff with less product. The controlled 20–80 µm particle size ensures a smooth, non-gritty texture that is comfortable on skin and easy to incorporate across systems—from pressed and loose powders to liquid and gel formats.

Key Formulation Benefits

  • Dramatic Color Travel: Creates a high-impact copper-shifting effect that adds depth and multi-dimensionality to color cosmetics.
  • Superior Coverage & Payoff: Iron oxides provide excellent opacity and color saturation for professional-grade results.
  • Smooth & Luxurious Texture: Silica treatment and tight particle control yield a silky, blendable feel with refined shimmer.
  • Clean & Conscious Ready: TiO2-free, vegan, cruelty-free, and considered natural per ISO 16128 to meet modern clean beauty standards.
