What is calcium stearate made of?
stearic acid
Calcium stearate, the calcium salt of stearic acid derived from animal fats & oils or vegetable oils, with the chemical formula Ca(C18H35O2)2.
What is E470a?
E470a, the E number for the sodium, potassium or calcium salts of fatty acids.
How do you make calcium stearate?
the preparation technology of a high purity calcium stearate is characterized in that, high-purity stearic acid and calcium hydroxide are dropped into reactor in mass ratio at 85: 15, add an amount of water, stir and heat up, under 100 ℃ of conditions, react 90min, then through dehydration, dry, pulverizing, get …
What is the formula of stearic acid?
C18H36O2
Stearic acid/Formula
How much calcium is in calcium stearate?
The finished product is composed of calcium with variable proportions of stearic and palmitic acids, and contains the equivalent of 9-10.5% calcium oxide (Osol and Hoover 1975).
How do you dissolve calcium stearate?
Calcium Stearate will react with the HCL, hydrolyzing the metal salt into calcium chloride and fatty acid. To dissolve calcium stearate, you need a co-solvent system with polar and non-polar features. The ratio of the two is proportionate to the ratio of Ca to Stearate…or 10% MEK plus 90% Xylenes. Heat and stir.
Is calcium stearate dairy?
You can rest assured that the calcium stearate is plant derived, and that no animal products were used in the processing of our candy’s ingredients…
Is calcium stearate organic or inorganic?
Calcium stearate is a metallic, water soluble stearate. It is a compound of calcium with a mixture of solid organic acids obtained from edible sources, and consists chiefly of variable proportions of calcium stearate and calcium palmitate (NAS 1996).
Is calcium stearate safe to eat?
Calcium stearate is also used in cosmetics and food products. Calcium stearate is used in oral drug formulations and is reported as nontoxic and nonirritant. It is listed on the FDA Generally Regarded as Safe database.

How is calcium stearate produced in the body?
Calcium stearate is produced by heating stearic acid and calcium oxide: 2 C 17 H 35 COOH + CaO → (C 17 H 35 COO) 2 Ca + H 2 O. 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.
Is it safe to put calcium stearate in 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.
What kind of soap is a calcium stearate?
Calcium stearate is a carboxylate of calcium, classified as a calcium soap.
What can calcium stearate be used for in plastics?
Applications. 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.
