Question 1

What does MAY CONTAIN \ +/- SILICA do in a cosmetic formula?

Accepted Answer

This ingredient is typically used as an absorbent, texture modifier, anti-caking agent, and soft-focus powder in makeup and skin-care formulas. It can improve slip, reduce shine, and help pigments disperse more evenly.

Question 2

Is MAY CONTAIN \ +/- SILICA clean?

Accepted Answer

From a clean-beauty perspective, it is generally well tolerated on skin and not a major restricted-list concern in pressed or liquid formats. Loose, respirable powders and impurity control matter, so brands usually rely on cosmetic-grade material with appropriate particle-size and purity specifications.

Question 3

Is MAY CONTAIN \ +/- SILICA sustainable?

Accepted Answer

This material is mineral-derived or synthetically made from abundant inorganic feedstocks, so it does not rely on petrochemical farming inputs or threatened botanical supply chains. It is not biodegradable in the usual organic sense, but it is environmentally inert and not considered bioaccumulative.

Question 4

Is MAY CONTAIN \ +/- SILICA COSMOS-approved?

Accepted Answer

It is generally permitted under COSMOS when it is a compliant mineral or nature-identical grade that meets purity requirements, while nano or respirable-powder considerations may require additional scrutiny. Its Green Chemistry profile is strongest on inertness and low reactivity, and weaker on renewability and biodegradability.

Question 5

How does MAY CONTAIN \ +/- SILICA work chemically?

Accepted Answer

The molecule is an inorganic amorphous network solid built from silicon and oxygen tetrahedra, with surface hydroxyl groups that can bind water and oil at the particle surface. Use levels vary widely by product type, from low single digits for slip and oil control to much higher levels in powders, and it is broadly stable across normal cosmetic pH ranges.
