Sericite Mica ●
TL;DR. This ingredient is a mineral filler and texture modifier that adds slip, soft-focus diffusion, and a smooth powder feel. It is common in pressed powders, loose powders, eye products, foundations, and creams where glide and optical blurring matter.
What does Sericite Mica do in a cosmetic formula?
This ingredient is a mineral filler and texture modifier that adds slip, soft-focus diffusion, and a smooth powder feel. It is common in pressed powders, loose powders, eye products, foundations, and creams where glide and optical blurring matter.
Is Sericite Mica clean?
From a clean-beauty perspective, it is generally inert on skin and not a common sensitizer, but loose airborne particles can be a practical concern for inhalation during application or manufacturing. Clean standards usually focus on particle-size control, trace heavy-metal testing, and responsible sourcing documentation.
Is Sericite Mica sustainable?
This material is mined, so it is nonrenewable and depends heavily on traceable extraction and labor practices. It is environmentally persistent as an inert mineral, but it is not expected to bioaccumulate or break down into reactive byproducts.
Is Sericite Mica COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic frameworks when sourced as an allowed mineral and processed with accepted physical methods. Its Green Chemistry profile is mixed, with low chemical transformation and high stability, but nonrenewable sourcing and lack of biodegradability limit alignment.
How does Sericite Mica work chemically?
The molecule is a layered aluminosilicate mineral with platy particles that reflect and scatter light while improving slip between skin and pigment particles. Use levels vary widely, from low single digits in emulsions to much higher levels in powder color cosmetics, and it is broadly pH-stable and oxidation-resistant under normal cosmetic conditions.
