Sericite Mica (Triethoxycaprylylsilane Coated)

Sericite Mica (Triethoxycaprylylsilane Coated)

Hydrophobically treated sericite designed for improved dispersion, adhesion, and long-wear 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 provides enhanced compatibility with oil phases and improved water resistance compared to untreated grades. The Triethoxycaprylylsilane surface treatment increases pigment binding, reduces clumping, and improves wear 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 results in better payoff, smoother glide, and improved durability in makeup applications, especially where long wear and moisture resistance are desired.

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 dry phase of powders.
• Disperse into oil phase for anhydrous formulations.
• Compatible with silicones, esters, and treated pigments.

Formulation Notes

• Improves water resistance and long-wear properties.
• Enhances pigment dispersion and uniformity.
• Provides smooth glide with reduced drag.
• Ideal for high-performance and professional-grade formulations.

Common Applications

• Long-wear foundations
• Pressed powders and compacts
• Primers and hybrid systems
• Water-resistant makeup formulations
