Tin Oxide

What Tin Oxide is & what it does

A mineral used to enhance the sparkle and pearl effect of mica-based pigments and to improve their adhesion. It refines the look of shimmer.

What is Tin Oxide and what does it do in sunscreen?

Tin Oxide is a mineral used mainly with mica-based pigments to enhance their sparkle and pearl effect and help them stick better. In a tinted or glow sunscreen it refines the look of the shimmer and color rather than adding sun protection. It is a cosmetic colorant and finish ingredient.

Is Tin Oxide a UV filter?

No. Despite being a mineral oxide like zinc oxide and titanium dioxide, Tin Oxide is not a sunscreen filter and does not block UV. It is used to improve the appearance of pigments and shimmer. The actual sun protection in these products comes from the listed UV filters.

Is Tin Oxide safe?

Yes. Tin Oxide is an inert mineral used as a cosmetic colorant and is considered safe as used. It sits on the surface within the pigment system rather than penetrating the skin, and reactions are uncommon. It is generally suitable for sensitive skin.

Does Tin Oxide clog pores?

No. It is an inert mineral powder used in small amounts to refine pigments, not an oil or wax, so it is not considered comedogenic. It is an unlikely cause of breakouts. Any clogging concern with a tinted product is more likely from the emollient base than from the mineral colorants.

Is Tin Oxide natural or synthetic?

It is a mineral oxide, processed for cosmetic use. The raw material is mineral in origin, then purified and milled to the fine, consistent powder needed to work with mica and pigments. So it is mineral-based rather than plant-based or animal-derived.
