It is a calcium salt of stearic acid, a long-chain fatty acid found in animal and vegetable fats. This compound exhibits unique properties that make it indispensable in industries such as ✔️ plastics, ✔️ rubber, ✔️ pharmaceuticals, ✔️ food, and ✔️ cosmetics.
👉 What is Calcium Stearate?
Calcium Stearate is a chemical compound that belongs to the category of metal stearates. It is the calcium salt of stearic acid, which is a long-chain saturated fatty acid.
Calcium stearate is a white, fine powder that is insoluble in water but soluble in organic solvents. This compound is widely used for its unique properties and versatile applications in various industries.
Calcium stearate is composed of calcium ions (Ca2+) and stearate ions, derived from stearic acid.
Chemical Formula: Ca(C18H35O2)2
👉 Production of Calcium Stearate
Calcium Stearate is typically produced by reacting stearic acid with calcium oxide (quicklime) or calcium hydroxide (hydrated lime). This reaction results in the formation of calcium stearate and water as a byproduct. The chemical equation for this reaction is as follows:
2C18H35COOH + CaO -> Ca(C18H35COO)2 + H2O
After the reaction, the calcium stearate is purified, dried, and processed into the desired form, such as a fine powder or pellets.
👉 Properties of Calcium Stearate
➡️ Lubricating and Emulsifying
Calcium Stearate is known for its lubricating properties, which make it effective in reducing friction and enhancing the flow of materials. It also has emulsifying properties that aid in mixing substances that would not normally dissolve in each other.
This compound is hydrophobic, meaning it repels water. This property makes it useful in applications where moisture resistance is required.
Calcium Stearate can withstand relatively high temperatures without decomposition, making it suitable for applications in industries where heat is involved.
➡️ Stabilizing and Binding
In various industries, Calcium Stearate acts as a stabilizer, ensuring consistent performance of products, and as a binder, helping ingredients stick together in formulations.
