Science
Mechanism of Action
Operating as a 'molecular sponge,' Attapulgite utilizes a needle-like crystalline network to create a physical trap on the skin's surface. This three-dimensional lattice physically adsorbs excess sebum, environmental toxins, and bacterial matter into its internal voids, allowing for their mechanical removal and providing an immediate mattifying effect.

Key findings
- 01 A 6-week clinical trial utilizing palygorskite masks 2-3 times weekly demonstrated a significant reduction in inflammatory acne lesions, including papules and pustules.
- 02 Research indicates that a 5% concentration effectively manages moisture and exudate in compromised skin barriers due to high liquid-binding capacity.
- 03 Concentrations between 2-5% have been validated to serve as both effective oil adsorbents and stable emulsion stabilizers.
Transparency
Dusting Analysis
To achieve measurable oil-adsorption and anti-acne benefits, Attapulgite must typically be present at 2% or higher; concentrations below 1% suggest it is being used merely for bulk or claim-substantiation rather than functional skin performance.
The Formula
Formulation
Stability
Physically and chemically stable across diverse temperatures; can be 'heat-activated' to enhance adsorption capacity. It naturally yields an alkaline pH in aqueous suspension.
Synergies
- Non-ionic surfactants
- Other mineral adsorbents (Kaolin/Bentonite)
- Glycerin
Conflicts
- Cationic surfactants
- Hydrocortisone
Safety
Safety Profile
Safety is conditional on the delivery method; it is restricted in sprayable products to prevent the inhalation of fine crystalline dust.
