GRADE
A combined surface-treatment approach integrating silica with organosilane chemistry for maximum photostability, optical blur, and low reactivity.
Direct evaluation batch for formulators and R&D teams
VTD-50AS represents our dual-barrier surface chemistry technology. The titanium dioxide core is first encapsulated with a dense amorphous silica shell to neutralize photo-catalytic surface activity and trap free radicals under UV irradiation. An outer layer of triethoxycaprylylsilane is then grafted to ensure optimal dispersibility in lipophilic vehicles.
The silica interlayer delivers optical light-scattering (soft-focus blurring) while the organosilane outer mantle ensures swift incorporation in high-SPF formulations.
High-SPF broad-spectrum sunscreens, anti-aging creams, premium photostable foundations, performance coatings.
25 kg sealed valve bags with desiccated inner lining.
We welcome opportunities to collaborate with formulators, manufacturers, distributors and technology partners looking for reliable surface-treated powder solutions.
