Method of applying magnesium-rich calcium montmorillonite to skin for oil and organic compound sorption

摘要

A method of increasing the bulk density and improving the water- dispersibility, oil sorption capacity, and body dirt and oil removability by compacting and/or shearing a magnesium rich calcium montmorillonite clay. In an optional embodiment of the present invention, silica gel, sodium silicate, acrylic polymers and copolymers, carboxy methyl cellulose, or other materials capable of providing lubricity to the surface of the clay crystals is added to the clay, prior to shearing, to enhance the compaction and/or shearing process and further increase the bulk density of the clay. The clay is sheared in an extruder, pug mill or California-type pellet mill when the clay includes about 20% to about 45%, preferably about 25% to about 40% by weight water, based on the dry weight of the clay.
