Quaternium-90 Bentonite ●
TL;DR. This ingredient is a rheology modifier and suspending agent, used to thicken anhydrous systems and help keep pigments or powders evenly dispersed.
What does Quaternium-90 Bentonite do in a cosmetic formula?
This ingredient is a rheology modifier and suspending agent, used to thicken anhydrous systems and help keep pigments or powders evenly dispersed.
Is Quaternium-90 Bentonite clean?
From a clean-beauty perspective, it has friction because it is a synthetically modified mineral rather than a simple untreated mineral. Finished-product skin irritation is usually low, but raw-material dust control and trace free cationic residues are relevant quality checks.
Is Quaternium-90 Bentonite sustainable?
This material starts with a mined mineral substrate and is altered with a synthetic cationic treatment, so it is not a strongly renewable ingredient. The mineral portion does not biodegrade, and the organic treatment is less aligned with readily biodegradable ingredient choices.
Is Quaternium-90 Bentonite COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic as a synthetically surface-modified mineral. Its Green Chemistry fit is limited by mining, synthetic modification, and weak biodegradability, even though it can improve formula stability at low use levels.
How does Quaternium-90 Bentonite work chemically?
The molecule system is a layered aluminosilicate mineral whose surface is modified to become more compatible with oils, waxes, and solvents. Typical use is often in the low single digits for viscosity building or suspension, and performance depends on shear, proper wetting, and activation by the surrounding oil phase.
