Calcium Stearate is a calcium-based substance containing a combination of solid organic acids derived from dietary sources.Because of its lubricating and water-repelling characteristics, it is commonly employed as an anti-caking agent in food, cosmetics, and medicines.Cosmetics and culinary items include this chemical. This is safe to use. Calcium Stearateis a benign and non-irritant ingredient included in oral medication formulations.Its most commonly employed as a solid-phase lubricant to minimize friction between particles in the substance to which its introduced.
Calcium Stearate Properties:

12. Miscibility: Insoluble in polar solvents like water, but soluble in nonpolar solvents like mineral oils, vegetable oils, and organic solvents (e.g., ethanol, benzene)
13. Hygroscopicity: Low to moderate (absorbs moisture from the atmosphere but not as much as some other compounds)
14. Surface Tension: Calcium stearate can reduce the surface tension of liquids, which aids in their wetting and spreading properties.
Frequently Asked Questions:
Q: What is calcium stearate?
A: Calcium stearate is a chemical compound derived from stearic acid. It is a white, waxy powder that is insoluble in water. It is commonly used as a lubricant, stabilizer, and anti-caking agent in various industries.
Q: What are the uses of calcium stearate?
A: Calcium stearate has a wide range of applications. It is commonly used as a release agent in the production of plastics, rubber, and polyolefin resins. It also serves as a lubricant in the manufacturing of cosmetics, pharmaceuticals, and personal care products. Additionally, it can be found in food products as an anticaking agent and stabilizer.
Q: How does calcium stearate function as a lubricant?
A: Calcium stearate functions as a lubricant by reducing friction between particles or surfaces. When added to a material, it forms a thin layer that separates the particles, preventing them from sticking together and improving the flow properties of the substance.
Q: What are the benefits of using calcium stearate as a release agent?
A: As a release agent, calcium stearate prevents materials from sticking to molds, dies, or processing equipment during manufacturing. It facilitates the easy removal of finished products from molds and helps achieve smooth and defect-free surfaces.
Q: Is calcium stearate safe for consumption?
A: Yes, calcium stearate is generally recognized as safe for consumption by regulatory authorities such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). It is commonly used as a food additive, where it acts as an anticaking agent and stabilizer.
Q: Can calcium stearate be used in pharmaceutical applications?
A: Yes, calcium stearate is commonly used in the pharmaceutical industry. It serves as a lubricant in tablet manufacturing, where it helps improve the flowability of powders, prevents sticking to punches and dies, and facilitates the ejection of tablets from molds.
Q: Does calcium stearate have any environmental impacts?
A: Calcium stearate is generally considered safe for the environment. It is non-toxic and has low aquatic toxicity. However, excessive amounts released into water bodies may have an impact on aquatic life, so proper disposal and waste management practices should be followed.
Q: Can calcium stearate be used in cosmetics?
A: Yes, calcium stearate is commonly used in cosmetic formulations. It functions as a lubricant, thickening agent, and emulsion stabilizer. It helps improve the texture and spreadability of cosmetics and contributes to the stability of emulsions.
Q: Are there any known health risks associated with calcium stearate?
A: Calcium stearate is considered safe for use in normal conditions. However, like any chemical substance, exposure to high concentrations or prolonged inhalation of its dust may cause respiratory irritation. It is important to follow proper handling and safety guidelines when working with calcium stearate.
