Calcium Stearate

shutterstock_519137797Calcium stearate is a fine, white powder. It is an insoluble salt of calcium, stearic acid, and palmitic acid.

Calcium stearate, which is recognized as physiologically safe, has become increasingly important in recent years. Calcium stearate is insoluble in most solvents. It dissolves only slightly when heated in aromatic compounds, chlorinated hydrocarbons or vegetable and mineral oils and waxes.

Calcium stearate is primarily used as a release agent, lubricant and acid scavenger by the rubber and tire industry.
