Science
Mechanism of Action
This synthetic layered silicate primarily controls viscosity by forming unique quick-breaking (thixotropic) gels when concentrations exceed 2% in water, which contributes to a luxurious, smooth skin feel. It significantly improves the structural integrity and stability of formulations by enhancing emulsion stability and effectively preventing the settling of particles, pigments, and active ingredients. Additionally, it can impart a matt, soft-focus appearance, accelerate drying times in film-forming products, and in certain applications, provide a mild abrasive or polishing effect to aid in skin surface cleansing.
