Calcium stearate is carboxylate of calcium that is found in some lubricants and surfactants. It is a white waxy powder. Calcium stearate is used as a flow agent in powders including some foods (such as Smarties), a surface conditioner in hard candies such as Sprees, a waterproofing agent for fabrics, a lubricant in pencils and crayons. The concrete industry uses calcium stearate for efflorescence control of cementitious products used in the production of concrete masonry units i.e. paver and block, as well as waterproofing. In paper production, calcium stearate is used as a lubricant to provide good gloss, preventing dusting and fold cracking in paper and paperboard making. In plastics, it can act as an acid scavenger or neutralizer at concentrations up to 1000ppm, a lubricant and a release agent. It may be used in plastic colorant concentrates to improve pigment wetting. In rigid PVC, it can accelerate fusion, improve flow, and reduce die swell. Applications in the personal care and pharmaceutical industry include tablet mold release, anti-tack agent, and gelling agent. Calcium stearate is a component in some types of defoamers.
Cosmetics
Calcium stearate is generally used for its lubricating properties. It maintains emulsions from separating into oil and water phases in cosmetics and personal care products.
Pharmaceuticals
Calcium stearate is an excipient that can be used as a mold-release agent (to help machines run fast) in the manufacturing of pharmaceutical tablets and capsules.
Plastics
Calcium stearate is used as a lubricant, stabilizer release agent and an acid scavenger in the manufacturing of plastics, such as PVC and PE.
Food
It can be used as a solid-phase lubricant to prevent ingredients and finished products from sticking caused by absorbing
moisture.In bread, it is a dough conditioner that functions as a free-flowing agent, and is commonly used together with other dough softeners such as mono- and diglycerides.
