Sericite Mica (Triethoxycaprylylsilane Coated)

Sericite Mica (Triethoxycaprylylsilane Coated)

Hydrophobically treated sericite designed for improved dispersion, adhesion, and long-wear cosmetic performance.

INCI Name: Mica (and) Triethoxycaprylylsilane

Appearance: Fine, soft white to off-white powder

Solubility: Insoluble; highly dispersible in oils and anhydrous systems

Function: Adhesion enhancer, texture modifier, hydrophobic performance filler

This silane-treated sericite mica provides enhanced compatibility with oil phases and improved water resistance compared to untreated grades. The Triethoxycaprylylsilane surface treatment helps improve pigment binding, reduce clumping, and support smoother application in high-performance cosmetic systems.

Supplied as a cosmetic raw material for formulation use.

What It Does

Triethoxycaprylylsilane treatment creates a water-repellent surface that improves dispersion in oils and enhances formulation stability. This helps improve payoff, glide, wear resistance, and overall texture in cosmetic applications.

Typical Use Levels

• 3–10% — Sensory and adhesion improvement
• 10–40% — Structural filler in powders and foundations
• Up to 60% — Base material in dry cosmetic systems

How to Incorporate

• Blend into the dry phase of powder formulations.
• Disperse into the oil phase for anhydrous systems.
• Compatible with silicones, esters, treated pigments, and many emollients.

Formulation Notes

• Improves water resistance and long-wear properties.
• Enhances pigment dispersion and uniformity.
• Provides smoother glide with reduced drag.
• Supports high-performance cosmetic textures.
• Useful in both pressed and loose powder systems.

Common Applications

• Long-wear foundations
• Pressed powders and compacts
• Primers and hybrid systems
• Water-resistant makeup formulations
• Anhydrous cosmetic bases
• Pigment and filler blends

Useful when formulators want powders to feel elegant instead of dusty drywall. Cosmetic chemistry remains humanity’s most sophisticated method of making beige particles behave.
