This product is insoluble in water, ethanol or ether, and is mainly used as a lubricant, anti-adherent, and flow aid. It is particularly suitable for the granulation of oils and extracts, and the resulting granules have good fluidity and compressibility. Used as a flow aid in direct tableting. It can also be used as a filter aid, clarifier and defoamer, as well as suspending agent and thickener for liquid preparations.
