For chemical buyers and R&D professionals, a thorough understanding of a product's chemical properties and handling requirements is crucial for successful integration into manufacturing processes. Calcium Stearate, a widely used industrial additive, possesses distinct characteristics that dictate its application and safety protocols. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated supplier, provides insights into these essential aspects.

Chemical Composition and Solubility

Calcium Stearate is the calcium salt of stearic acid, a long-chain saturated fatty acid. Chemically, it is often represented as Ca(C₁₇H₃₅COO)₂. It typically appears as a fine, white, waxy powder. Its solubility profile is noteworthy: it is insoluble in water, cold ethanol, and ether but exhibits solubility in hot benzene, turpentine, and other organic solvents. This limited solubility in water makes it an excellent choice for applications where water resistance is required, such as in waterproofing agents for textiles or concrete. When purchasing Calcium Stearate, consider your specific solvent compatibility needs.

Thermal Stability and Decomposition

A key advantage of Calcium Stearate is its commendable thermal stability. It remains stable under normal temperatures and pressures. When heated to approximately 400°C, it begins to decompose slowly. In the presence of strong acids, it can decompose into stearic acid and corresponding calcium salts. Its relatively high melting point, typically in the range of 147-149°C, contributes to its effectiveness in high-temperature processing applications, particularly in plastics. For manufacturers demanding consistent performance at elevated temperatures, sourcing our high-purity Calcium Stearate is a strategic choice.

Handling and Storage Best Practices

While generally considered non-toxic, proper handling and storage of Calcium Stearate are essential to maintain its quality and ensure workplace safety. It is hygroscopic, meaning it can absorb moisture from the air, which can affect its flowability and performance. Therefore, it should be stored in tightly sealed containers in a cool, dry, and well-ventilated area. When handling the powder, it is advisable to wear appropriate personal protective equipment (PPE), such as dust masks, safety goggles, and gloves, to avoid inhalation or skin contact. As a reliable Calcium Stearate supplier, we emphasize the importance of adhering to these guidelines.
