Mineral sunscreens are in demand from Indian consumers who want gentle, broad-spectrum protection. The challenge has always been white cast and heavy feel. Here is how modern formulation solves it.
Why zinc oxide alone?
Zinc oxide protects across UVB and UVA. Removing titanium dioxide simplifies the filter system and suits brands positioning on gentle, mineral-only protection.
Beating white cast
Particle size, dispersion quality and the emollient system determine how transparent a mineral sunscreen looks on darker Indian skin tones. Well-dispersed zinc oxide in a lightweight base spreads clear.
What the numbers mean
- In-vitro SPF is measured in the lab on a substrate and is useful for development.
- In-vivo SPF is measured on human volunteers and is what pack claims should be based on.
- PA++++ is the highest UVA protection grade.
Ecosmetix’s mineral sunscreen uses 25% zinc oxide and 0% titanium dioxide at pH 6.5, with in-vitro SPF 70, in-vivo SPF 50+ and PA++++ results. The same base scales across SPF 15, 30, 50 and 70.
