Titanium Dioxide
What is Titanium Dioxide?
Titanium dioxide is a naturally occurring inorganic compound, an oxide of titanium extracted from mineral ores like rutile and anatase, appearing as a bright white powder. In cosmetic products such as sunscreens, foundations, moisturizers, and lotions, it belongs to physical UV filters, pigments, and texturizers. It works by scattering and reflecting ultraviolet light across UVA and UVB spectra due to its high refractive index, creating a barrier on the skin surface. As a colorant, it delivers pure whiteness and coverage; as an opacifier, it imparts a creamy, non-transparent finish that hides imperfections and stabilizes visuals. Finely milled or nano forms improve blendability and reduce visible residue, maintaining product integrity without chemical reactivity.
