P.A.T Calcium Stearate is a fine, white powder. It is an insoluble salt of calcium, stearic acid, and palmitic acid. Recognized as physiologically safe, calcium stearate has gained increasing importance in recent years. This substance remains insoluble in most solvents. While it dissolves only slightly when heated in aromatic compounds, chlorinated hydrocarbons, or vegetable and mineral oils and waxes,
