KT-68860311 Sparkle Yellow Diamond Effect Cosmetic Pigment Powder

KT-68860311 belongs to Kolortek's 68800000 Cosmetic Pearl Multicolor Series — a line engineered specifically for decorative cosmetic and personal care applications. The base material is calcium-aluminum borosilicate (not standard synthetic fluorphlogopite or natural mica), which gives this series its signature properties: unusually high transparency, a smooth flat-flake geometry, and an extremely high refractive index. The result is a pigment that produces genuine diamond-like sparkle rather than a standard pearl or satin finish.

The yellow color component is derived from Yellow 5 (CI No. 19140), combined with titanium dioxide and tin dioxide surface coatings. This combination locks in color stability while preserving the optical clarity of the borosilicate substrate.

Product Model & Specifications

The 60–300 μm particle size range is intentional. Larger flakes within this range produce the high-intensity sparkle points characteristic of a diamond effect. Smaller flakes in the distribution fill in the base shimmer. Together, they generate a layered visual depth that finer-particle pearlescents typically cannot replicate.

Related Series

KT-68860311 sits within a broader portfolio. Depending on your formulation target, adjacent series may also be relevant:

• Cosmetic Pearl Multicolor Series (68800000): Core series for colorful, high-sparkle cosmetic effects.
• Borosilicate / Dreamstar Series: Shares the same substrate technology; available in a wide range of colors and effects.
• Glitter Series (Cosmetic Grade): Includes Advanced Multicolors, Laser Biodegradable, and Cellulose-based biodegradable glitters — suitable where glitter aesthetics or sustainability requirements apply.

Applications

KT-68860311 is formulated for decorative cosmetics and personal care systems. Verified use areas include:

• Eyeshadows — pressed, loose, and baked formats
• Face powders and setting powders
• Blushers and highlighters
• Foundations (where visible sparkle is part of the finish goal)
• Mascaras and eyeliners
• Soaps (Cosmetic Multicolor Series is compatible)

In practice, this pigment is most effective in applications where the final product is viewed under direct or angled light — environments where the borosilicate substrate can express its full reflective range. For matte-dominant or diffused-light formulations, the effect is subdued and this product would likely be over-specified.

Key Characteristics

The performance profile of KT-68860311 is tied directly to its substrate. Calcium-aluminum borosilicate has a higher refractive index than standard mica, which translates to brighter, sharper reflections at the flake surface. The smooth, flat geometry of the flakes means light bounces cleanly rather than scattering — producing the sparkle point effect rather than a diffused glow.

Worth noting: the transparency of the borosilicate base allows the Yellow 5 colorant to appear vivid and clean rather than muddy. This is a meaningful distinction when formulating against color targets. The yellow reads as saturated and bright, not washed out by an opaque substrate.

Key technical attributes:

• High refractive index — strong, directional light response
• Unusual transparency of substrate — color clarity and depth
• Big, smooth flake structure — clean sparkle points, not diffuse shimmer
• Broad particle size distribution (60–300 μm) — layered visual texture
• Color: Sparkle Yellow (Yellow 5 / CI-19140 based)

Practical Formulation Considerations

The 60–300 μm particle range requires attention during dispersion. High-shear mixing is not recommended — it will fracture the larger flakes and reduce the sparkle intensity significantly. Low-shear or hand-mix incorporation, added late in the process, is standard practice for borosilicate-based pigments at this particle range.

In pressed powder formats, compaction pressure should be evaluated. Excessive pressing compresses the flake orientation and reduces the three-dimensional sparkle character. Test batches at lower compression pressures before finalizing the process.

That said, dispersion in liquid systems — clear gels, serums, or liquid foundations — is generally straightforward. The smooth flake surface means the pigment moves freely and orients well under light mixing. Surface treatment options are available for specific compatibility requirements; contact the technical team for guidance.

The cosmetic shimmer pigment formulation is designed to meet regulatory requirements across multiple markets including US, EU, and Japan. MSDS, TDS, and COA documentation is available on request.

FAQ

Q: Is KT-68860311 suitable for lip applications?
The product page for this specific SKU does not list lip use as a confirmed application. For face and eye applications it is confirmed. If lip use is a requirement, consult directly with Kolortek's technical team to verify compliance and ingredient suitability for that application: contact@kolortek.com.

Q: How does the Yellow 5 (CI-19140) colorant affect regulatory compliance in different markets?
Yellow 5 / CI-19140 has different regulatory status across markets. It is permitted in cosmetics in the US and EU under specific conditions, but regional restrictions do apply depending on application site and concentration. Kolortek formulates the Cosmetic Multicolor Series to address multi-regional requirements, but formulators should verify compliance for their specific market and product type. Full documentation — including MSDS and COA — is available to support regulatory submissions.

Q: Can the particle size distribution be customized?
Kolortek offers customization support across its effect pigment lines. If the standard 60–300 μm distribution does not align with your formulation requirements — for instance, if you need a tighter cut for a specific application — contact the technical team to discuss options.

Q: What mixing equipment is recommended during incorporation?
Low-shear equipment is strongly preferred. Given the 60–300 μm particle range and the flat borosilicate flake structure, high-shear mixers will fracture flakes and degrade sparkle performance. Planetary mixers, paddle mixers, or manual incorporation late in the batch process are standard approaches for this type of pigment.
