Kaolin Clay ●
TL;DR. This ingredient primarily functions as an absorbent, opacifier, texture modifier, and mild polishing agent. It helps manage shine, add slip in powders, and give masks or cleansers a soft, paste-like feel.
What does Kaolin Clay do in a cosmetic formula?
This ingredient primarily functions as an absorbent, opacifier, texture modifier, and mild polishing agent. It helps manage shine, add slip in powders, and give masks or cleansers a soft, paste-like feel.
Is Kaolin Clay clean?
From a clean-beauty perspective, this ingredient is generally well tolerated and has little restricted-list friction when used in standard cosmetic formats. The main practical concern is airborne powder exposure during manufacturing or loose-powder use, where good particle-size control and dust management matter.
Is Kaolin Clay sustainable?
This material is a naturally mined mineral, so its footprint depends on quarry practices, land management, and transport distance. It is inert in the environment rather than biodegradable, and it does not rely on petrochemical or palm-based feedstocks.
Is Kaolin Clay COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic frameworks when sourced and processed as an allowed mineral ingredient. Its Green Chemistry fit is strongest on low chemical transformation and simple physical processing, with the main limitation being nonrenewable mineral sourcing.
How does Kaolin Clay work chemically?
This material is a layered mineral with plate-like particles and surface hydroxyl groups, which explains its absorbency, opacity, and soft tactile feel. Typical use ranges run from about 1 to 10% in cleansers or powders and higher in rinse-off masks, often 10 to 40%, with broad pH stability but a need for good dispersion to limit settling or grittiness.
