Titanium Oxide ●
TL;DR. It is primarily a white mineral pigment and opacifier, adding opacity, brightness, and coverage. In sunscreens, selected coated grades also function as inorganic UV filters.
What does Titanium Oxide do in a cosmetic formula?
It is primarily a white mineral pigment and opacifier, adding opacity, brightness, and coverage. In sunscreens, selected coated grades also function as inorganic UV filters.
Is Titanium Oxide clean?
It is broadly accepted in clean-beauty frameworks, especially in non-nano, well-dispersed, surface-treated grades. The main friction is format-specific, with tighter scrutiny for inhalable loose powders and sprays, plus disclosure expectations for nano-sized particles.
Is Titanium Oxide sustainable?
This material comes from mined mineral feedstocks and requires energy-intensive refining. It is not biodegradable, but it is highly insoluble and generally behaves as an inert particulate, with the footprint driven mostly by mining, processing, particle size, and surface coating choices.
Is Titanium Oxide COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets mineral-origin, purity, and particle-size requirements, with nano use subject to specific assessment and labeling. Its Green Chemistry fit is mixed, with abundant mineral origin and strong stability balanced against mining impacts, refining energy, and no biodegradation pathway.
How does Titanium Oxide work chemically?
The molecule is an insoluble inorganic mineral lattice with a very high refractive index, which explains its strong whitening, coverage, and UV-scattering behavior. Typical use ranges from below 1% for opacity adjustment to regulated sunscreen-active levels up to about 25%, and performance depends heavily on dispersion quality, particle size, and surface coatings such as silica, alumina, fatty acids, or silicone materials.
