KT-699135 Dark Purple Synthetic Mica Pearlescent Pigment Cosmetic

KT-699135 belongs to Kolortek's 699000 series — a line of cosmetic-grade pearlescent pigments based exclusively on synthetic mica substrates. The optical effect in this series is generated by direct deposition of light-absorbing materials onto the mica platelet, producing a characteristic split between the reflection angle (silver) and the dispersion angle (absorption color — in this case, dark purple).

The coating stack includes Titanium Dioxide, Tin Oxide, Iron Oxide, and Ferric Ferrocyanide — a combination that contributes to both the depth of the purple tone and the interference brightness. This is not a straightforward iron oxide pigment. The layered structure is engineered to produce an effect that reads differently depending on viewing angle and light source, which is part of what makes it useful in finish-sensitive cosmetic applications.

Product Specifications

Applications

KT-699135 is developed specifically for cosmetic and personal care use. It is not a general-purpose effect pigment — the purity requirements, coating composition, and particle size are all oriented toward skin-contact applications where both performance and safety compliance matter.

Typical use areas include:

• Eyeshadow — pressed, loose, and baked formats
• Highlighters and illuminating powders
• Lip color products (lipstick, lip gloss, liquid lip)
• Face and body glitter formulations
• Nail color systems
• Setting powders and color-effect primers

In practice, this pigment performs well in both anhydrous and emulsion-based systems. Dispersion into oil or silicone carriers is straightforward at standard cosmetic loading levels. For water-based formulations, surface treatment or a pre-wet step may be worth considering depending on your system viscosity and desired suspension stability.

Key Characteristics

Several properties of this product are worth unpacking beyond the standard spec sheet.

Synthetic vs. natural mica substrate: The shift to synthetic mica is not purely cosmetic (in the industry sense). Synthetic mica is produced under controlled conditions, which results in fewer inclusions, near-zero heavy metal contamination, and significantly reduced black spot counts. For formulators working on clean-label or high-end SKUs, this matters both for aesthetics and compliance documentation. The mineral is also more uniform in platelet geometry, which contributes to the improved luster and chroma you see in the finished formula.

Thermal stability: Synthetic mica handles elevated processing temperatures better than natural mica. If you're working with hot-pour lipsticks, baked powder systems, or any format that involves heat exposure during manufacturing, KT-699135 is more stable and less likely to show color drift across the batch.

Weather resistance: This is more relevant for personal care products that see UV and humidity exposure (sunscreens, outdoor-use products). The synthetic base resists degradation better than natural mica under comparable conditions.

Color behavior at angle: The dark purple effect is the absorption color, visible from the side or dispersion angle. At direct reflection, the pigment reads silver. This dual behavior means the visual effect shifts with movement and light angle — relevant for finish design, particularly in eyeshadow and highlight products where the "flip" or sparkle behavior is part of the intended aesthetics.

Worth noting: the Ferric Ferrocyanide component (CI 77510) is well-established in cosmetic formulations and appears in many regulatory-approved color additive lists. That said, confirm inclusion limits and labeling requirements for your target markets, as rules vary by region.

Synthetic Mica vs. Natural Mica — Practical Comparison

Formulation Considerations

A few practical points for formulators incorporating KT-699135:

Dispersion method: For loose powder and pressed formats, dry blending is standard. Avoid high-shear mixing at extended durations — this can fracture the platelet structure and reduce the shimmer quality. In liquid systems, gentle stirring or low-shear paddle mixing is preferred.

Loading levels: Typical cosmetic loading ranges from 1–30% depending on format. Eyeshadows and highlighters often run higher; primers and base products typically lower. The optimal level should be determined in your specific matrix — optical behavior changes with concentration.

Compatibility: The pigment is compatible with the standard cosmetic ingredient palette — silicones, esters, waxes, and most gelling systems. No known compatibility issues with the common cosmetic surfactants and emulsifiers. As with any effect pigment, compatibility with strong acids, strong alkalis, or aggressive oxidizing agents should be tested if relevant to your formulation.

Regulatory documentation: MSDS, TDS, and COA are available. If you are working on a product destined for markets with specific colorant approval lists (US FDA, EU, China NMPA), confirm the regulatory status of all coating components in KT-699135 for your target channel before finalizing the formulation.

Frequently Asked Questions

Q: Is KT-699135 suitable for use directly on skin, including eye-area products?
A: Yes — KT-699135 is produced to cosmetic grade and is designed for skin-contact applications including eye-area products. That said, confirm the regulatory status of Ferric Ferrocyanide in your specific target market, as approval for eye-area use varies by jurisdiction.

Q: How does the dark purple color appear in a finished pressed eyeshadow?
A: The dark purple reads most clearly from the side and dispersion angle. At direct face-on reflection, the pigment contributes silver brightness. In a pressed pan, this creates a dynamic shift — the product will appear to change between silver-bright and deep purple depending on how light hits it. The effect is more pronounced at higher loading levels and in formats without heavy white or opaque filler dilution.

Q: Can this pigment be used in lip gloss or liquid lip products?
A: Yes. The particle size range (10–60 μm) and platelet morphology are compatible with typical lip gloss bases. Dispersion into castor oil or polybutene carriers works well. Monitor viscosity and settle behavior over time — a thickening agent or suspension aid may help in lower-viscosity systems if shelf stability is a concern.

Q: What certifications are available for this product?
A: Documentation available includes MSDS, TDS, and COA. Kolortek holds ISO 9001, REACH, SGS, and TÜV SÜD certifications, and offers Kosher certification as well. For specific compliance needs or custom documentation requests, direct inquiry to contact@kolortek.com.
