Calcium Stearate is a versatile and widely used compound with a diverse range of applications across various industries.

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.

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

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.

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.

In various industries, Calcium Stearate acts as a stabilizer, ensuring consistent performance of products, and as a binder, helping ingredients stick together in formulations.

Calcium stearate finds a wide range of applications across various industries worldwide, owing to its unique properties and characteristics. Some of its key applications are following:

One of the most significant applications of Calcium Stearate is in the plastics and polymers industry. It acts as a lubricant and release agent during processing, preventing sticking to equipment surfaces and improving the flow of the material. It is commonly used in PVC and other polymer processing.

In the rubber industry, Calcium Stearate is used as a stabilizer and processing aid. It assists in the dispersion of fillers, reduces stickiness during processing, and enhances the overall quality of rubber products.

In cosmetics and personal care products, Calcium Stearate functions as an emulsifier, stabilizer, and thickening agent. It contributes to the texture and consistency of creams, lotions, and makeup products.

Calcium Stearate is used in the pharmaceutical industry as a tablet disintegrant, binder, and flow enhancer. It ensures that tablet formulations disintegrate properly and have consistent properties.

Calcium Stearate is used as a water repellent and release agent in the production of construction materials such as concrete, ensuring easy release from molds and improving surface finish.

Calcium stearate is considered safe for use in food and food packaging. It is used as an anti-caking agent in powdered food products to prevent clumping and improve flowability.

Calcium stearate is used in the paints and coatings industry as a flatting agent to reduce gloss and enhance the matting effect of coatings.

Industries such as plastics, rubber, pharmaceuticals, and construction have been expanding in India. As a result, the demand for calcium stearate, which has diverse applications in these industries, has also been increasing. As industries become more regulated and quality-conscious, there has been a growing emphasis on using high-quality additives like calcium stearate. Manufacturers and producers are looking for suppliers that can provide consistent and compliant products.

As a buyer, understanding its properties, applications, and factors to consider will empower you to make informed decisions when purchasing calcium stearate for your specific needs. Choose a reputable supplier that offers high-quality products and excellent customer support to ensure the success of your projects and applications.
