Silica. May Contain: CI 77491 ●
TL;DR. This ingredient is used as an absorbent, opacifier, texture modifier, anti-caking agent, and mild abrasive in powders, makeup, skin care, and toothpaste. It can reduce greasiness, improve slip, and help suspend or mattify formulas.
What does Silica. May Contain: CI 77491 do in a cosmetic formula?
This ingredient is used as an absorbent, opacifier, texture modifier, anti-caking agent, and mild abrasive in powders, makeup, skin care, and toothpaste. It can reduce greasiness, improve slip, and help suspend or mattify formulas.
Is Silica. May Contain: CI 77491 clean?
From a clean-beauty perspective, this ingredient is broadly accepted and usually low-irritation on skin when used in cosmetic grades. The main caveat is inhalation exposure in loose powders, where particle size and dust control matter.
Is Silica. May Contain: CI 77491 sustainable?
This material is mineral-derived, abundant, and not associated with bioaccumulation. It is not biodegradable in the organic sense because it is inorganic, but it is generally inert in the environment, with mining and processing energy as the main sustainability considerations.
Is Silica. May Contain: CI 77491 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets mineral-origin and processing requirements. Its Green Chemistry profile is solid for inertness and low reactivity, though it is nonrenewable and does not offer a biodegradability advantage.
How does Silica. May Contain: CI 77491 work chemically?
This compound is an inorganic network built from silicon and oxygen, typically used as an amorphous cosmetic-grade powder rather than a crystalline respirable material. Use levels commonly range from below 1% for flow and sensory adjustment to 5% to 30% in powders or abrasive systems, and it is insoluble, oxidation-stable, and compatible across a broad pH range.
