BYK Laponite® XLG Synthetic Layered Silicate
Categories:	Ceramic; Clay
Material Notes:	Description: LAPONITE XLG is a synthetic layered silicate with a low heavy metals content. It is insoluble in water but hydrates and swells to give clear and colourless colloidal dispersions in water or aqueous solutions of alcohols. At concentrations of 2% or greater in water, highly thixotropic gels are obtained. Application: Used for imparting a shear sensitive structure to a wide range of personal care products. For formulation information refer to Laponite Technical Bulletin L211/97/d Information provided by Southern Clay Products
