TitaniumDioxide ●
TL;DR. This ingredient functions as a white pigment, opacifier, and mineral UV filter. It adds opacity, coverage, and UV attenuation in sunscreens, makeup, and complexion products.
What does TitaniumDioxide do in a cosmetic formula?
This ingredient functions as a white pigment, opacifier, and mineral UV filter. It adds opacity, coverage, and UV attenuation in sunscreens, makeup, and complexion products.
Is TitaniumDioxide clean?
From a clean beauty perspective, it is generally well tolerated on skin and has low sensitization potential. The main scrutiny is format-related, especially inhalable loose powders or sprays, plus nano-particle disclosure and particle coating choices.
Is TitaniumDioxide sustainable?
This material is mineral-derived, then purified, milled, and often surface-treated for cosmetic use. It is not renewable or biodegradable in the organic sense, and environmental questions are more relevant for very small particle forms released into waterways.
Is TitaniumDioxide COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets mineral, purity, and processing requirements, with nano forms and UV-filter uses subject to standard-specific and regional regulatory conditions. Its Green Chemistry fit is partial, with abundant mineral sourcing and strong stability balanced against mining, refining energy, and nonrenewable feedstock.
How does TitaniumDioxide work chemically?
This compound is an inorganic metal oxide with a high refractive index, which explains its strong visible-light opacity and UV attenuation. Cosmetic grades are often coated with silica, alumina, or fatty acids to improve dispersion and reduce photocatalytic activity, with typical use ranging from about 1 to 25% in sunscreens and about 0.1 to 10% as a pigment or opacifier.
