Question 1

What does SILICA. [+/- MAY CONTAIN / PEUT CONTENIR: CI 77491 do in a cosmetic formula?

Accepted Answer

This ingredient is a mineral absorbent, opacifier, texture modifier, and soft-focus powder used to reduce shine, improve slip, and help suspend pigments in makeup and skin care.

Question 2

Is SILICA. [+/- MAY CONTAIN / PEUT CONTENIR: CI 77491 clean?

Accepted Answer

Cosmetic-grade amorphous material is broadly accepted in clean-beauty frameworks and is generally well tolerated on skin. The main scrutiny is particle size and inhalation exposure in loose powders, plus control of respirable crystalline mineral impurities.

Question 3

Is SILICA. [+/- MAY CONTAIN / PEUT CONTENIR: CI 77491 sustainable?

Accepted Answer

This material is mineral-derived, abundant, and non-bioaccumulative, but it is non-renewable and does not biodegrade because it is inorganic. Its environmental profile is mainly tied to mining, purification, and dust control rather than aquatic persistence.

Question 4

Is SILICA. [+/- MAY CONTAIN / PEUT CONTENIR: CI 77491 COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic when it meets mineral-origin and purity requirements. From a Green Chemistry view, it scores well for inertness and low reactivity, with weaker alignment on renewability and biodegradability.

Question 5

How does SILICA. [+/- MAY CONTAIN / PEUT CONTENIR: CI 77491 work chemically?

Accepted Answer

This compound is an inorganic network solid made of silicon and oxygen atoms, typically used as porous amorphous particles with high surface area for oil absorption and sensory modification. Use levels vary widely by format, from low single digits in emulsions to much higher levels in powders, and it is stable across normal cosmetic pH and heat-processing conditions.
