UV Filter – MPT-171

Transparent UV filter with strong UVB protection and low skin irritancy.
Ideal for sunscreens requiring high transmittance and a smooth, non-whitening finish.

Advanced Nano Zinc-Based UV Filter for Clear Sun Protection Products

MPT-171 (15nm) is an ultra-fine particle rutile-grade UV filter designed for advanced sun care applications. With an average primary particle size of just 10nm and an absorption range between 290–320nm, it offers strong UVB protection while maintaining excellent transmittance in the visible spectrum. This makes it ideal for transparent sunscreen formulations that avoid the whitening effect commonly associated with inorganic UV filters.

Thanks to its low cohesiveness, MPT-171 disperses easily in the oil phase using a homogenizing mixer. It is low in heavy metals, safe for skin, and offers sustainable performance for modern sun care solutions.

NAGASE supplies MPT-171 globally to formulators of cosmetic and dermatological sun protection products – with reliable logistics and expert technical support.
