Calcium stearate is a highly regarded compound known for its safety and insolubility in most solvents. It exhibits solubility only in heated aromatic compounds, chlorinated hydrocarbons, and certain vegetable and mineral oils and waxes. The plastic industry extensively relies on calcium stearate as a lubricant, mold release agent, and acid breaker. In pharmaceutical and cosmetic applications, it serves as an anti-caking additive for powders and granules, as well as a compressing aid for tablets. Furthermore, the construction industry utilizes calcium stearate as a hydrophobic agent to protect buildings and structures from moisture absorption. It is commonly used alongside other stearate salts, such as zinc stearate and barium stearate, as a stabilizer for PVC. Within the rubber industry, it acts as a lubricant, release agent, and softening agent. In the realm of abrasive paper, calcium stearate functions as a lubricant and sanding sealer. Additionally, it finds application as a food additive, feed additive, and cosmetic ingredient.
