Calcium stearate is non-toxic white, fine powder, insoluble in water. When mixed with hot, strong mineral acids, they decomposed into stearic acid and corresponding calcium salts. When certain types of fatty acids are heated with an alkaline substance, the resulting salt is known as soap. Stearic acid is one of the most widely used components of soaps. Calcium stearate is a synthetic ingredient formed through a reaction when stearic acid and calcium oxide are heated together. It is the most important type of calcium salt, but due to its lack of solubility, it is not commonly used in soap in modern times, having been replaced by synthetic substances that are water soluble. Calcium stearate is widely used in cosmetics, plastics, and pharmaceuticals. This salt is used as a plasticizer, stabilizer, and surfactant.

Calcium stearate applicaton
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.Â
Calcium Stearate used as an internal Lubricant and helping
dispersion in Masterbatch.
In paper production, calcium stearate is used as a lubricant to
provide good gloss, preventing dusting and fold cracking in paper
and paperboard making.
Calcium Stearate is very compatible for all plastic
application,
Calcium Stearate used Coatings application and especially for Paint
Industry.
Calcium stearate used as a lubricant for styrene resin, phenol
resin, amino resin,
Calcium stearateis generally used as a PVC heat stabilizer.
Calcium Stearate used as a lubricant for Polyolefin
Calcium Stearate used as a hydrophobic agent for construction
chemicalsÂ
In plastics, it can act as an acid scavenger or neutralizer at
concentrations up to ***0ppm, 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.
Calcium stearate is a component in some types of defoamers.
Used as a stabilizing agent in the forming of jawbreakers.
Calcium stearate is produced by heating stearic acid and calcium
oxide:
2 C*7H*5COOH + CaO → (C*7H*5COO)2Ca + H2O
Also, Calcium stearate (CAS NO.********0) is made by the action of
the sodium salts of the acids on a soluble calcium salt such as
calcium chloride (CaCl2).
