Cosmetic Mica Pigment KT-655121 Red Pearl Natural Mica Simple Ingredients

KT-655121 sits within the 655000 series — a range developed specifically around cosmetic-grade natural mica pigment substrates, coated with Titanium Dioxide and Tin Dioxide to produce colorful pearlescent effects. The red color tone comes from a controlled TiO₂/SnO₂ layering that generates interference-based color expression across the particle surface. The result is a pearlescent red effect with visible shimmer and soft-focus gloss rather than a flat or opaque red.

Particle size runs 10–60μm. That range sits comfortably in the zone used for most pressed and loose face powders, blush compacts, and eyeshadow formulations — fine enough for smooth skin feel, coarse enough to retain optical depth and sparkle. In practice, this size distribution disperses well in both dry powder blends and suspension-type systems with minimal processing.

Key Technical Specifications

Applications

KT-655121 is formulated for cosmetic and personal care use. Typical applications include:

• Face powders and loose powder foundations
• Blushers and bronzers
• Eyeshadows, eyeliners, mascaras
• Lip-area products where red pearl tones are needed
• Nail art formulations
• Artisan and melt-and-pour soaps

Worth noting: the simple three-ingredient declaration makes KT-655121 particularly useful when developing products for markets with stricter ingredient labeling requirements or clean beauty positioning. No dye components, no organic pigment co-coatings — the pearlescent color is generated purely through optical interference.

Series Context — How KT-655121 Fits

The 655000 series is part of Kolortek's broader Cosmetic Pearl Multicolor range, which spans multiple color families. Where the KT-100 and KT-200 series focus on silver-white and iridescent interference effects respectively, the 655000 series is explicitly designed to produce defined color identities — red, gold, green, violet — while keeping the ingredient profile consistent and regulatorily clean.

For reference, if you need an interference-type red with stronger angular color shift (dual-color flip behavior), the KT-215 from the KT-200 Interference Series is worth evaluating. It uses the same base chemistry but produces a more pronounced iridescent red-to-complementary-color effect depending on viewing angle. KT-655121, by contrast, reads as a stable red pearl — consistent, warm, and less angle-dependent. The right choice depends entirely on the visual language of the formulation.

Formulation Considerations

KT-655121 is a dry powder and should be handled accordingly. For pressed powder systems, standard pigment dispersion practices apply — progressive addition with low-shear blending preserves particle integrity and optical performance. High-shear milling is not recommended; it will reduce particle size and shift the visual effect toward a flatter, less lustrous appearance.

In suspension systems — gels, emulsions, liquid foundations — the pigment can be pre-dispersed in a carrier or added directly to the oil phase. Compatibility with most standard cosmetic bases is good given the inert mineral surface. That said, if your formulation uses aggressive surfactant systems or extreme pH conditions, sample testing is the only reliable way to confirm stability.

Recommended use levels vary by application type. In eyeshadows and face powders, loading rates of 5–30% are typical. In emulsion and gel formats, lower concentrations (2–10%) are more common to maintain texture and spreadability. These are starting points — final optimization depends on the carrier system and the target intensity.

For formulators targeting cosmetic mica pigments with regulatory compliance built in, the straightforward INCI of KT-655121 reduces documentation complexity across EU, US, and Asia-Pacific markets. Kolortek provides full documentation support including TDS, MSDS, and COA on request.

Regulatory and Quality Notes

Products in the 655000 series are developed to meet multiple international cosmetic ingredient standards. Kolortek holds ISO 9001 certification and products are supported by SGS, TÜV SÜD, REACH, Kosher, and Cruelty-free documentation. Batch-to-batch consistency is maintained through in-house QC, with COA available per batch.

FAQ

Q: Is KT-655121 approved for use in eye area cosmetics?
KT-655121 uses Mica, Titanium Dioxide, and Tin Dioxide — a combination that is accepted for eye area cosmetic use under EU Regulation and broadly recognized in other major markets. That said, regulatory suitability depends on your final product claim and local market requirements. Review the relevant regional colorant lists and confirm with your regulatory team before finalizing label claims.

Q: What distinguishes this from synthetic mica-based red pigments?
KT-655121 uses a natural mica substrate. Synthetic mica (Fluorphlogopite) offers higher brightness and better chemical resistance, but the ingredient declaration changes and the cost is higher. Natural mica works well in the majority of standard cosmetic formulations and is widely accepted. If your formulation requires enhanced whiteness or strict heavy metal limits below what natural mica can achieve, the SynStar synthetic mica series would be the alternative to evaluate.

Q: Can KT-655121 be used in soap formulations?
Yes. It is used in both melt-and-pour and cold process soap. Dispersion in a small amount of oil or glycerin before incorporation into the soap base gives the most even color distribution. The mineral-based coating is generally stable in saponification environments, though cold process soap's high-pH conditions mean sample testing is advisable when working with a new formulation.

Q: What documentation is available for procurement and compliance purposes?
Kolortek provides TDS, MSDS, and COA as standard. Compliance documentation including REACH, SGS test reports, and other certifications can be provided on request. For private label or custom packaging inquiries, contact contact@kolortek.com.
