Science
Mechanism of Action
As an organically modified clay, Stearalkonium Bentonite functions by forming a gel structure within cosmetic emulsions, thereby increasing viscosity and conferring a rich, luxurious texture. Its stabilizing properties are crucial for preventing phase separation in complex formulations. Furthermore, its inherent absorbent capabilities make it beneficial for formulations targeting oil control, while its rheology-modifying action ensures improved spreadability and application consistency on the skin.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed alkonium clays, including Stearalkonium Bentonite, safe for cosmetic use when formulated to be non-irritating. While a severe ocular irritant at 100% concentration, it was not irritating to intact or abraded rabbit skin at 100% nor to guinea pig skin at 60%. Patch testing is advisable for initial use, particularly for individuals with sensitive skin.
