What is Zinc Oxide?
Zinc Oxide (INCI: Zinc Oxide) is a mineral UV filter and skin protectant. It provides broad-spectrum protection against UVA and UVB, and is also used in barrier creams, diaper creams and soothing ointments for its mild anti-inflammatory and astringent properties.
How It Works
Zinc oxide reflects and scatters UV radiation across the UVA-UVB range, acting as a physical sunscreen. On irritated skin it forms a soothing barrier that helps retain moisture and calm redness, which is why it appears in both sun care and barrier-repair formulations.
Market Context for Brand Owners
Zinc oxide cream is a top Amazon US search at roughly 90,000 monthly searches, driven by mineral sunscreen demand plus diaper and barrier cream use. Clean-beauty preference for mineral filters keeps it a high-volume private-label category.
Formulation & Manufacturing Notes
Zinc oxide is oil-dispersible and requires good dispersion to avoid whitening. Micronized or coated grades reduce the white cast. It is compatible with most oils, butters and emollients; avoid combining with strong acids that can release free zinc ions.
Regulatory Status
Zinc oxide is a permitted mineral UV filter in the US (OTC sunscreen monograph), EU and Korea at regulated concentrations. Sunscreen products must follow local labeling and claim rules (e.g., SPF testing).
