Pearlescent Effect KT-68835 Violet Green Mica Pigment Cosmetic Grade

KT-68835 belongs to Kolortek's 68800 Series — a line of cosmetic multicolor pearlescent pigments built on a natural mica substrate. The optical behavior here is interference-based: light-absorbing layers deposited directly onto the mica platelet produce two distinct color readings depending on viewing angle. From the specular (reflection) angle, you see a clean silver light. Rotate to the dispersion angle, and the violet-green absorption color comes through. That dual-angle behavior is what separates interference pigments from standard tinted micas.

The pigment is cosmetic grade throughout — formulated to meet the compositional and safety expectations of eye-area applications, which tend to carry the most stringent requirements in decorative cosmetics. It disperses well in typical cosmetic matrices without requiring aggressive milling.

Technical Specifications

Applications

KT-68835 is suited for a range of decorative cosmetic and personal care formats. The cosmetic-grade certification makes it directly usable in eye-area products, which opens up the full decorative spectrum. Typical applications include:

• Eyeshadows — pressed, loose, and cream formats
• Eyeliners and mascaras
• Face powders and setting powders
• Foundations requiring shimmer enhancement
• Blushers and highlighters
• Lip products where interference shimmer is desired
• Personal care products with decorative finish requirements

In practice, the violet-green shift performs best in pressed powder formats and loose eye products, where the angular color play is most visible and the particle geometry is least disrupted during processing.

Key Characteristics

Dual-angle visual effect. The defining feature of this pigment is its angle-dependent color behavior. At the specular angle, the surface reflects silver-white light. As the viewing angle shifts toward dispersion, the violet-green absorption color becomes dominant. This is a function of thin-film interference, not dye concentration — so the effect is inherently stable.

Natural mica substrate. The platelet base is natural mica, which provides the layered structure necessary for interference coatings and gives the powder its characteristic soft feel and smooth application on skin.

Shimmer and gloss output. KT-68835 contributes both shimmer and gloss to formulations — shimmer from particle orientation variation, gloss from the high-reflectance surface of the coated mica platelets. The two effects interact to produce the visual depth typical of quality violet green mica interference pigments.

Cosmetic compliance. The ingredient set — mica, titanium dioxide, tin oxide, iron oxide, ferric ferrocyanide — is within the established colorant frameworks for cosmetic use, including eye-area applications. That said, formulators should always verify compliance against the regulatory framework of their target market before commercialization.

Practical Considerations

Dispersion method matters. KT-68835 should be incorporated with minimal shear to preserve platelet integrity. High-shear mixing or aggressive milling will fracture the mica platelets, reduce particle size distribution, and degrade the interference effect — the result is a duller, less chromatic output. Gentle blending or spatula incorporation is generally preferred in dry cosmetic systems.

In wet systems (emulsions, gels, liquid foundations), add the pigment at the end of the process, after temperature-sensitive steps are complete. Avoid prolonged exposure to elevated temperatures during processing.

Worth noting: the angular color shift is most dramatic when the pigment is used at sufficient loading and in formulations that allow platelet orientation. Compressed powder formats with high binder content can suppress the effect if the platelets are locked in random orientations. Thin film applications — like eyeshadow pressed cakes or loose powders — tend to show the full effect at standard use levels.

Typical use levels in cosmetic formulations range from 1–10% depending on the format and desired intensity. Blending with complementary mica pigments for cosmetics from the same 68800 series is straightforward and allows custom color effects without compatibility concerns.

Frequently Asked Questions

Is KT-68835 approved for use in eye-area cosmetics?
The pigment is formulated as cosmetic grade and the ingredient composition is consistent with colorant use in eye-area products. Kolortek can provide MSDS, TDS, COA, and relevant certificates to support your regulatory review. Final compliance determination should be made against the specific regulations of your target market (EU Cosmetics Regulation, US FDA, etc.).

How does the violet-green color shift actually appear in a finished product?
At direct (specular) viewing, the product surface reads as silver-white. As the viewing angle changes — or as light catches the pigment from the side — the violet-green interference color becomes visible. The shift is subtle to pronounced depending on loading level, particle orientation, and the transparency of the surrounding matrix. Clearer or less pigmented bases tend to show the shift more distinctly.

Can this pigment be blended with other effect pigments or standard cosmetic colorants?
Yes. KT-68835 blends well with other mica-based effect pigments, including others in the 68800 Series, as well as with standard cosmetic colorants. Physical compatibility is generally not an issue in dry systems. In wet systems, ensure the matrix chemistry (pH, surfactant type) is compatible with the pigment surface.

What documentation is available for procurement and regulatory purposes?
Kolortek provides MSDS, TDS, COA, and formulation guidelines as standard. Certification documentation — including ISO 9001, REACH, SGS, TÜV SÜD, and Kosher — is available on request depending on market requirements.
