  • Synthetic layered silicate exhibiting tolerance to electrolytes in applications thereof
    Publication number: 20030077337
    Abstract: A synthetic layered silicate material may be produced which exhibits tolerance to high levels of electrolytes and surfactants as measured by viscosity, hydration rate and clarity. The synthetic layered silicate material may produce similar or improved rheological properties when compared to natural hectorite at comparable or lower addition rates in select aqueous systems.
