Calcium Stearate

Cas No: 1592-23-0

Calcium stearate is carboxylate of calcium that is found

in some lubricants and surfactants. It is a white waxy

powder.

Calcium stearate is produced by heating stearic acid, a

fatty acid, and calcium oxide:

It is also the main component of soap scum, a white

solid that forms when soap is mixed with hard water.

Unlike soaps containing sodium and potassium, calcium

stearate is insoluble in water and does not lather well.

Commercially it is sold as a 50% dispersion in water or as

a spray dried powder.
