Question 1

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

Accepted Answer

This ingredient is used as a water-repellent film-former, skin-conditioning agent, and surface treatment for pigments and powders. It helps improve slip, reduce tack, and make mineral colorants disperse more evenly.

Question 2

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

Accepted Answer

This ingredient has clean-standard friction because many retailer and certification programs flag persistent synthetic organosilicon materials, even though skin irritation potential is generally low. It is mainly a standards and environmental persistence issue rather than a common sensitizer issue.

Question 3

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

Accepted Answer

This material is made through mineral-derived silicon chemistry with fossil-derived organic inputs, not renewable plant feedstocks. It is not considered readily biodegradable and can persist in aquatic and sediment environments.

Question 4

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

Accepted Answer

It is not permitted under COSMOS-natural or COSMOS-organic because synthetic organosilicon polymers are outside the allowed ingredient scope. Its Green Chemistry fit is weak because it relies on nonrenewable inputs and has limited biodegradability.

Question 5

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

Accepted Answer

The molecule is a low- to medium-molecular-weight organosilicon polymer with a silicon oxygen backbone, methyl substitution, and some silicon hydrogen functionality that can react with hydroxylated mineral surfaces. It is typically used at low levels as a pigment treatment or sensory film former, and it is stable across normal cosmetic pH ranges when properly formulated.
