UV Filter – DIF Series

The DIF Series is a high-performance liquid dispersion of ultrafine zinc oxide from the FINEX technology platform, designed for formulating transparent and elegant mineral sunscreens. Engineered for optimal particle stability, dispersibility, and clarity, DIF zinc oxide dispersions deliver exceptional UVA shielding without whitening—ideal for next-generation sun care and daily wear SPF products.

By combining ultrafine particle size control with advanced surface treatments, the DIF Series ensures smooth integration into creams, lotions, and fluid products while maintaining excellent photostability. These dispersions provide reliable broad-spectrum UV protection and are suitable for sensitive, baby, and acne-prone skin due to their gentle, non-irritating profile.
