Kolortek KT-68824B Red Blue Pearlescent Mica Pigment for Cosmetics

KT-68824B sits within the 68800 color pearlescent series — a line developed specifically for cosmetic-grade use. The pigment produces a red interference color at direct reflection angles, while a blue absorption tone becomes visible from oblique or dispersion angles. This two-angle color behavior is characteristic of interference-based pearlescents and gives formulators a tool for depth and visual complexity that solid-color pigments simply can't replicate.

The mica substrate here is natural mica — not synthetic fluorphlogopite — which affects how it disperses and how it reads on skin. Natural mica tends to deliver a softer, more diffuse shimmer compared to synthetic alternatives. For cosmetic applications where skin feel and natural aesthetics matter, this is often the preferred choice.

Product Series Reference

The 68800 series covers a range of multicolor interference effects, each engineered for cosmetic-grade performance. KT-68824B is one of the red-blue variants in that line.

Key Characteristics

• Dual-angle color shift: Silver-white from the reflection angle; red-blue absorption color visible from the side or oblique dispersion angle.
• Natural mica base: Provides a smooth, skin-compatible carrier with well-established safety data for cosmetic use.
• Ingredient composition: Mica, Titanium Dioxide, Tin Oxide, Prussian Blue — all with documented use in color cosmetics.
• Particle size range: 10–60 μm — suited for most cosmetic formats without requiring additional milling in standard formulations.
• Shimmer and gloss: Delivers both fine shimmer and surface gloss, depending on loading level and application medium.

Worth noting: Prussian Blue (Iron Blue) as a component is a cosmetic-approved colorant in many markets, but regulatory status varies by region. Formulators should verify compliance against applicable regulations — particularly for eye area products — before finalizing formulations.

Applications

KT-68824B is designed for decorative cosmetics and personal care products. Typical use cases include:

• Eyeshadows and eye palettes
• Highlighters and face powders
• Lip glosses and lip lacquers
• Nail color formulations
• Body shimmer and luminizing products

In practice, the red-blue color play works particularly well in products viewed at multiple angles — eyeshadows and nail lacquers are natural fits. The interference effect reads cleanly against both light and medium skin tones, giving formulators flexibility in positioning.

Formulation Considerations

As a dry cosmetic mica pigments powder, KT-68824B can be incorporated into pressed and loose powder systems, emulsions, and anhydrous formulations. A few practical points:

• Dispersion: Avoid high-shear mixing during incorporation. Excessive mechanical stress can fracture the mica platelets, reducing particle size and degrading the shimmer effect. Gentle paddle mixing or manual blending is preferred for maintaining particle integrity.
• Loading levels: Effect intensity scales with concentration, but overloading in emulsion systems can create texture issues. Start at 1–5% and adjust based on the carrier system and target effect.
• Compatibility: Compatible with standard cosmetic emollients, waxes, and film formers. No known issues with typical cosmetic preservative systems. That said, always run compatibility checks specific to your formulation before scaling.
• Surface treatment: Confirm whether the supplied batch carries any surface coating that might affect adhesion or spreadability in specific substrates — particularly for gel or water-based formats.

FAQ

Q: Is KT-68824B safe for use in eye area cosmetics?
The formulation contains Prussian Blue, which has restricted use status in some regulatory frameworks for eye area products. Confirm applicability under your target market's regulations (EU Cosmetics Regulation, FDA 21 CFR, etc.) before using in eye-contacting products.

Q: What is the difference between the red and blue color in this pigment?
KT-68824B is an interference pigment. The red tone appears at the direct specular reflection angle (face-on view), while the blue absorption color is visible from oblique or dispersion angles. This angular color difference is what creates the perceived depth and "flip" effect in finished products.

Q: Can this mica pigment powder be used in liquid lip products?
Yes. KT-68824B is suitable for oil-based and anhydrous lip formulations such as lip glosses and lip oils. For water-based systems, ensure adequate dispersion and check for sedimentation at your target viscosity before finalizing the formula.

Q: Is documentation available for regulatory submissions?
Kolortek holds ISO 9001, REACH, SGS, and TÜV SÜD certifications, and relevant compliance documentation can be requested. Contact the technical team directly for SDS, TDS, or compliance certificates specific to KT-68824B.
