Ingredients Details
Bentonite
Common Name(s): Montmorillonite,volcanic ash clay,swelling clay
CAS Number: 1302-78-9
DESCRIPTION
What It Does: Provides thixotropic clay gellation and deep oil absorption from swelling smectite clay.
Why It's Used: Strongest adsorbing clay for deep cleansing masks โ bentonite's high cation exchange capacity and swelling capacity provide the deepest oil and toxin adsorption of common cosmetic clays.
How It Works: Montmorillonite 2:1 layered silicate swells up to 15ร in water via interlayer water absorption. very high cation exchange capacity (cec: 80-150 meq/100g) provides exceptional adsorption of cations, oils, and toxins. thixotropic gel provides 'mask that hardens' sensory experience.
Typically Found In: Clay masks,deep cleansing products,detoxifying formulas

SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.

Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Bentonite's extraordinary swelling (up to 15ร dry volume) arises from its 2:1 layer structure: sodium bentonite's inter-layer sodium cations attract very thick water shells, forcing the silicate layers apart by electrostatic repulsion. calcium bentonite swells only 2-3ร by comparison, explaining why sodium-exchanged bentonite is the industrial standard for swelling applications.
