Hectorite is a trioctahedral clay mineral with surface reactivity and adsorption, cation exchange capacity. It can interact between organic molecules with the active sites of the interlayer, surface, edge and inter-particle via ion exchange, intercalation and grafting. In recent years, the clay minerals-microbes interaction has been investigated, which represents microbial bioremediation and biodegradation of pollutants. In this work, we obtained fermented hectorite of the reaction with Lactobacillus plantarum as a chemical modifier to provide morphological properties. We demonstrated that the interaction of hectorite with Lactobacillus ferment enhanced the dispersion stability by preventing aggregation and promoting its diffusion without any pressure, and improved removal efficiency for particular pollutant by wedge film formation. Thus, the study suggested that the fermented hectorite may have a promising potential for use as a novel cosmetic ingredient.
