TIN OXIDE

Safety grade: A**

Tin oxide is a fine mineral powder derived from tin that adds texture and smoothness to cosmetic products. It helps create a lighter, more refined feel in powders and other formulations.

Tin oxide is used in cosmetics as a gentle abrasive for exfoliation, as a thickening agent to improve product texture, to make products more opaque and light-reflective, and to control how thick or thin the product feels.
