Question 1

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

Accepted Answer

This ingredient is a white opacifying pigment used to brighten, lighten, and increase coverage in color cosmetics and skin care. In regulated sunscreen formulas, it can also function as a mineral UV filter.

Question 2

Is \ +/- May Contain: Ci 77891 / Titanium Dioxide clean?

Accepted Answer

From a clean-beauty perspective, it is broadly accepted in creams, pressed powders, and color cosmetics, with more scrutiny for respirable loose powders, sprays, and nano-scale grades. It is generally low-irritation on skin, but clean standards often ask for particle-size transparency and appropriate surface coatings.

Question 3

Is \ +/- May Contain: Ci 77891 / Titanium Dioxide sustainable?

Accepted Answer

This material is mineral-derived, so its footprint is tied to mining, purification, and energy-intensive processing rather than agricultural sourcing. It is not biodegradable because it is inorganic, but it is insoluble and not expected to bioaccumulate like persistent organic compounds.

Question 4

Is \ +/- May Contain: Ci 77891 / Titanium Dioxide COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic standards as an allowed mineral-derived colorant or functional mineral ingredient, subject to grade, coating, and nano-material rules. Its Green Chemistry profile is mixed, with good stability and low skin reactivity, but non-renewable sourcing and processing intensity keep it from being a perfect fit.

Question 5

How does \ +/- May Contain: Ci 77891 / Titanium Dioxide work chemically?

Accepted Answer

The molecule is an inorganic oxide used for very high refractive index, opacity, and light scattering, with rutile and anatase crystal forms and common surface treatments to improve dispersion. Typical use can range from below 1% for shade adjustment to several percent for coverage, and up to regulated sunscreen-use ranges where permitted, with rutile and coated grades preferred for lower photocatalytic activity.
