Uses & Applications

Calcium stearate has many potential uses, including as a flow agent, stabilizing agent and surface conditioner in the production of certain foods — notably, many candies. It is used as a mold-release agent for pharmaceutical tablets and capsules, as an anti-caking agent in cosmetics and as a thickener in lubricants and greases. It is also a stabilizer found in many plastics and is used to process concrete and paper.
