Calcium stearate is carboxylate of

calcium that is found in some lubricants and surfactants. It is a white waxy

powder.

Production and occurrence

Calcium stearate is produced by

heating stearic acid, a fatty acid, and calcium oxide:

 2 C17H35COOH + CaO ? (C17H35COO)2Ca + H2O

It is also the main component of

soap scum, a white solid that forms when soap is mixed with hard water.[2] Unlike soaps containing sodium and potassium, calcium

stearate is insoluble in water and does not lather well.[citation needed]

Commercially it is sold as a 50% dispersion in water or as a spray dried powder. As a food additive it is known by the generic E number E470.

Applications

 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.[4]

 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.

Calcium stearate is a non-toxic,

white powdery substance. It is a calcium salt derived from stearic acid and is

widely used in cosmetics, plastics, and pharmaceuticals. This salt is used as a

plasticizer, stabilizer, and surfactant. It is a substance that the U.S. Food

and Drug Administration has generally recognized as safe when used as a food

additive.

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.

This substance is frequently found

in cosmetics, however, especially aerosol hair styling products. It is also

found in cosmetic powders, ointments, and packaging. Despite a very low risk

for dermal irritation, topical contact may cause redness, itching, and eye

irritation.

Calcium Stearate is an insoluble

salt of calcium, stearic acid and palmatic acid. In hard water, when soap of

calcium ions is mixed, the scum that is formed is calcium stearate. Calcium

stearate is non-toxic and has many applications as stabilizer and lubricant.

Besides water, it is insoluble in water, ether, chloroform, acetone, cold

alcohol as well. However, it is slightly soluble when dissolved in hot alcohol,

hot vegetable and mineral oil. It shows good solublity in hot pyridine.

The use of calcium stearate is

seen widely as a stabilizer for PVC resins and lubricant for plastic moulding

powders or tablets. Its use is recommended also in emulsions, cements, pencils,

construction chemicals, paint flattening agent, resin coated sands and foundry

chemicals, decaking agent in food items like onions and cosmetics. Use of

calcium stearate is seen as a lubricating agent in paper and paperboard coating

compositions, iron wire drawing and leather cloth manufacturing as well. Its

use has been extended as a neutralizer, colour stabilizer, reducer of fiber

breakage and de-agglomerator in PP and HDPE applications.

Calcium stearate is also known as

octadecanoic acid calcium salt, stearic acid calcium salt.

Also available as Granular powder

and Coarse powder. Butyl stearate is used as a flow agent in powders including

some foods, a waterproofing agent for fabrics, and a lubricant in pencils and

crayons. The concrete industry uses calcium stearate for efflorescence control

of cementious products used in the production of concrete masonry units i.e.

paver and block, as well as waterproofing. In the paper industry, 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, a lubricant and a release agent. Applications in the personnal

care and pharmaceutical industry include tablet mold release, anti-tack agent

and gelling agent.

Suggested Application

?As a stabilizer & lubricant

in rigid PVC processing, PVC compounding & moulding, in Leather cloth

manufacturing etc.

? As a lubricant  in iron wire drawing.

? As an anti caking agent in

Detergent Cakes.

? In cosmetics.
