Sun protection grade zinc oxide
A non-nano mesoporous zinc oxide powder specifically tailored for suncare formulators- one mineral filter, broad-spectrum coverage across UVA & UVB, and a transparent finish that is optimised for peak UV attenuation.
Absorbance coverage · 280–700nm
Zincox UVx's native absorbance spans the full UVB and UVA range on its own — no blending required to close the spectrum.
Why formulators reach for it
The properties that carry through from raw powder to finished formulation.
Individual particles run from a few to several tens of nanometres, but they cluster into highly porous aggregates measuring up to a few micrometres — keeping the powder outside nano classification.
Supplied as an uncoated/coated powder that stays transparent in-formula even at high loadings — the open mesopores allow cosmetic carrier fluids to match the particles refractive index, making it virtually invisible on the skin.
The mesoporous channels wick and absorb excess sebum throughout the day, so the powder keeps performing as a mattifying agent long after application — the result is a soft-focus, non-greasy finish that formulators consistently favour over conventional zinc oxide grades.
The particle architecture is engineered to scatter and absorb across the full UVA and UVB range rather than favouring one band, giving formulators a single mineral filter that delivers balanced, broad-spectrum protection without needing to pair it with additional actives.
A high BET surface area means more active surface per gram of powder, so formulations reach their target SPF at lower usage levels — translating into a meaningful efficacy boost without the heavier, chalkier feel that comes with conventional zinc oxide loadings.
