Key Applications
Cosmetics and Skincare
Used in whitening creams, sunscreens, vanishing creams, and moisturizing lotions due to its excellent UV-blocking and brightening properties. TiO₂ enhances opacity and skin protection in various cosmetic formulations.
UV-Resistant Coatings and Films
Applied in food packaging films, plastic materials, and exterior coatings to prevent UV degradation and extend product life.
Photocatalysis and Environmental Cleanup
Employed in photocatalytic degradation of organic pollutants, wastewater treatment, and air purification systems. Anatase TiO₂ nanoparticles generate reactive oxygen species under UV light, breaking down contaminants.
Antibacterial and Self-Cleaning Surfaces
Integrated into glass, ceramic tiles, and paints to enable surfaces that self-sterilize under UV light and prevent microbial growth.
Printing Inks and Pigments
Improves brightness and opacity in high-end inks and pigments, offering consistent coverage and whiteness.
Paper, Metallurgy, and Aerospace Applications
Improves the printability and whiteness of specialty papers. Also used in producing titanium metal, ferrotitanium alloys, and carbide-based high-performance materials for aerospace.
