Surface treatment modifies the interface between the powder and the surrounding formulation system. Untreated mineral powders naturally exhibit high surface energy, hydrophilic tendencies, and a propensity to agglomerate in liquid or oil-based media.
At VELTRRIX Materials Technology, our treatment technologies are designed around distinct surface-chemistry approaches tailored to optimize dispersion, hydrophobicity, tactile skin-feel, and stability across demanding emulsion and powder systems.
Each treatment technology alters the substrate’s thermodynamic surface properties to meet specific vehicle and sensory requirements.
Surface modification using silicone-based chemistry for enhanced compatibility and formulation interaction. Creates a durable hydrophobic envelope that improves slip, eliminates greasiness, and provides water-resistant skin cling.
Organosilane-based surface treatment designed to modify powder surface characteristics and improve compatibility with selected formulation systems. Covalently bonds to particle surfaces to offer low oil absorption and fast wetting in cosmetic esters and oils.
A combined surface-treatment approach integrating silica with organosilane chemistry. Employs a dual-matrix coating that shields photochemically active sites while imparting organosilane-mediated dispersibility and soft-focus optical properties.
Surface modification of silica using cetyl alcohol chemistry. Imparts a deeply moisturizing, cushion-soft sensorial feel to silica beads, eliminating dryness and chalkiness in high-porosity powders while preserving oil control.
Depending on grade and formulation requirements, our treated powders can be evaluated for applications across diverse industries:
High-purity body powders, soothing dustings, sweat-resistant deodorants, and conditioning antiperspirant systems requiring silky sensory feel and moisture-buffering.
Face powders, translucent setting compacts, pore-blurring powders, and hybrid skincare-makeup primers demanding soft-focus optical diffusion and shine reduction.
Liquid foundations, concealers, pressed powder eyeshadows, cream blushes, and long-wear lipsticks benefiting from intense color purity and true-to-tone payoff.
High-SPF mineral sunscreens (W/O, W/Si), anti-aging daily creams, mattifying serums, and barrier protectants requiring photostability and zero whitening drag.
Performance industrial finishes, matte architectural coatings, plastic masterbatches, and anti-corrosive primer films requiring low oil absorption and weatherability.
Custom-engineered powder blends, optical diffusion master compounds, silicone elastomer suspensions, and novel client-specific material formulations.
We welcome opportunities to collaborate with formulators, manufacturers, distributors and technology partners looking for reliable surface-treated powder solutions.
