Titanium Dioxide ●
TL;DR. This ingredient is a mineral UV filter, opacifier, and white colorant. In sunscreens, it helps provide broad-spectrum UV coverage when evenly dispersed and properly coated.
What does Titanium Dioxide do in a cosmetic formula?
This ingredient is a mineral UV filter, opacifier, and white colorant. In sunscreens, it helps provide broad-spectrum UV coverage when evenly dispersed and properly coated.
Is Titanium Dioxide clean?
Clean-beauty frameworks generally accept it in lotions, creams, and pressed formats, with extra scrutiny for nanoscale grades and inhalable powders or sprays. It is usually low-irritation on skin, but particle size, coating, and product format matter.
Is Titanium Dioxide sustainable?
This material comes from mined mineral feedstocks and requires energy-intensive refining and particle processing. It is inorganic and not biodegradable, but it is generally inert in finished products, with environmental questions centered on ultrafine particle release.
Is Titanium Dioxide COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets the standard’s criteria, including documentation for particle size and any surface treatments. From a Green Chemistry view, it is durable and low-reactivity, but it is mineral-derived, non-renewable, and not biodegradable.
How does Titanium Dioxide work chemically?
The molecule is an insoluble inorganic metal oxide used in micronized or pigmentary particle form, with performance driven by particle size, crystal form, dispersion quality, and surface coatings such as silica, alumina, or fatty acids. In sunscreens, levels commonly range from about 2% to 25%, and coated grades are preferred to improve dispersion, reduce photocatalytic reactivity, and maintain stability across typical cosmetic pH ranges.
