Quaternium-90 Sepiolite ●
TL;DR. This ingredient is a rheology modifier and suspension stabilizer. It builds thixotropic structure in oils or anhydrous systems, helping keep pigments, minerals, and powders evenly dispersed.
What does Quaternium-90 Sepiolite do in a cosmetic formula?
This ingredient is a rheology modifier and suspension stabilizer. It builds thixotropic structure in oils or anhydrous systems, helping keep pigments, minerals, and powders evenly dispersed.
Is Quaternium-90 Sepiolite clean?
From a clean-beauty perspective, it has friction because it is a synthetically surface-treated mineral rather than a simple natural clay. Dermal irritation is usually low at cosmetic use levels, but some standards scrutinize cationically modified materials.
Is Quaternium-90 Sepiolite sustainable?
This material comes from a mined mineral that is chemically modified, with at least part of the modification typically derived from synthetic feedstocks. It is not readily biodegradable, and its footprint is tied to mining, processing, and the persistence of inert mineral particles.
Is Quaternium-90 Sepiolite COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic because the synthetic cationic modification does not fit the standard’s allowed treatment of mineral ingredients. Its Green Chemistry fit is mixed, since it can support low-solvent anhydrous formulas, but it relies on nonrenewable mineral sourcing and a non-biodegradable inorganic backbone.
How does Quaternium-90 Sepiolite work chemically?
This material is an organophilic, cationically modified fibrous magnesium silicate that forms a shear-dependent particle network rather than dissolving. Typical use is often around 0.5% to 5%, with performance shaped by shear, oil polarity, and the presence of activators or dispersing aids.
