Question 1

What does [+/- May Contain / Peut Contenir: Ci 77891 / Titanium Dioxide do in a cosmetic formula?

Accepted Answer

This ingredient is used mainly as a white pigment and opacifier, adding coverage, brightness, and opacity to color cosmetics and complexion products. In sunscreens, it can also serve as a mineral UV filter.

Question 2

Is [+/- May Contain / Peut Contenir: Ci 77891 / Titanium Dioxide clean?

Accepted Answer

From a clean-beauty perspective, it is broadly accepted in creams, lotions, and pressed or non-aerosol color products, with the main scrutiny focused on inhalable powders, sprays, and nano-scale forms. It is generally low-irritation on skin and is often used in products for sensitive skin.

Question 3

Is [+/- May Contain / Peut Contenir: Ci 77891 / Titanium Dioxide sustainable?

Accepted Answer

This material is mineral-derived, so it is not renewable and depends on mining and mineral refining. It is inorganic and not biodegradable, but it is also chemically stable and not expected to bioaccumulate in the way many persistent organic compounds can.

Question 4

Is [+/- May Contain / Peut Contenir: Ci 77891 / Titanium Dioxide COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic standards as an approved mineral colorant or filter when relevant purity and form restrictions are met. Its Green Chemistry profile is mixed, with good stability and low skin reactivity, but nonrenewable sourcing and limited biodegradability.

Question 5

How does [+/- May Contain / Peut Contenir: Ci 77891 / Titanium Dioxide work chemically?

Accepted Answer

The molecule is an inorganic metal oxide used as fine particles that scatter visible light strongly, which explains its opacity, whitening effect, and coverage in formulas. It is stable across typical cosmetic pH ranges, insoluble in water and oils, and often surface-treated to improve dispersion, reduce clumping, or improve compatibility with emulsions and anhydrous systems.
