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
TECHNICAL DETAILS
Primary Category: Functional ingredient โ swelling clay mineral
Secondary Functions: Skin conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 1%โ25%
SOURCING & ETHICS
Vegan Status: Yes โ natural mineral
Halal Status: Yes
Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 โ very low
Comedogenicity Rating: 0/5 โ non-comedogenic
Sensitivity Concerns: Well-tolerated by most skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Good safety profile at recommended concentrations. ewg score: 1โ2.
Works Well With: Standard skincare actives
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.

Hydroxyethyl Acrylate/sodium Acryloyldimethyl Taurate Copolymer
Common Name(s): Hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer
DESCRIPTION
What It Does: Provides antioxidant protection, soothing anti-inflammatory effects, and skin-conditioning benefits through plant-derived polyphenols and phytochemicals.
Why It's Used: Plant extracts concentrate bioactive phytochemicals evolved for environmental protection โ uv, microbial, and oxidative stressors โ that translate to skin benefits.
How It Works: Polyphenols (flavonoids, phenolic acids) inhibit nf-ฮบb-mediated inflammatory signaling, scavenge reactive oxygen species through electron donation, and chelate pro-oxidant metal ions to reduce oxidative skin damage.
Typically Found In: Lotions,creams,serums,masks
TECHNICAL DETAILS
Primary Category: Minerals
Secondary Functions: Skin-conditioning
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1โ10%
SOURCING & ETHICS
Vegan Status: Yes
Halal Status: Yes
Source Notes: Mineral-derived ingredient; no biological origin.
SKIN COMPATIBILITY
Irritancy Rating: 1
Comedogenicity Rating: 0
Sensitivity Concerns: Low sensitization potential at recommended use concentrations.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Well-characterized cosmetic ingredient with established safety profile. generally non-irritating at typical use concentrations. suitable for leave-on and rinse-off cosmetics.
Works Well With: Plant extracts,peptides,vitamins
Avoid Combining With: Strong chelating agents (reduce mineral availability)
SCIENTIFIC NOTE
Plant secondary metabolites (flavonoids, terpenes, phenolic acids) are biosynthesized as defense compounds against uv, herbivores, and pathogens. their anti-inflammatory activity typically derives from competitive inhibition of cox-2 and 5-lox enzymes (ic50 1โ50 ยตm), while antioxidant activity involves single electron transfer (set) and hydrogen atom transfer (hat) mechanisms with structure-dependent rate constants.
