Titanium Dioxide (Titanium Dioxide)

Titanium Dioxide is a widely used inorganic mineral ingredient valued in cosmetic formulations as a UV filter and opacifying/coloring agent. In sunscreens and daily photoprotection products, it functions as a physical UV filter by scattering and absorbing UV radiation, contributing primarily to UVB and short-wavelength UVA protection depending on grade, particle size, and surface treatment. In color cosmetics and personal care, it provides whiteness, opacity, and brightness, improving coverage and visual uniformity in foundations, concealers, powders, and skincare with tone-correcting or blurring claims. Titanium Dioxide is available in pigmentary and micronized/nano grades, and performance is strongly influenced by dispersion quality, coatings, and the overall vehicle; these factors also affect sensory feel and the potential for whitening/white cast. It is commonly incorporated into sunscreens, tinted moisturizers, primers, makeup, deodorants, and powders, with formulation strategies focused on stability, even application, and regulatory compliance for the intended use and market.
