Introduction

Calcium stearate is a versatile compound with significant applications across various industries. It is predominantly used as a stabilizer, lubricant, and release agent. In this article, the multifaceted uses of calcium stearate will be detailed, including its industrial, pharmaceutical, and food industry applications.

Calcium Stearate Overview

Calcium stearate is a white, wax-like powder derived from the salt of stearic acid and calcium. It is insoluble in water but has a range of solubility in organic solvents. Its chemical formula is C_36H_70CaO_4, and it exhibits a melting point between 149°C and 160°C.

Industrial Applications

The industrial sector utilizes calcium stearate extensively as a stabilizer and lubricant in the production of plastics, particularly in PVC manufacturing. It acts as an effective heat stabilizer, improving the material's durability and longevity. Furthermore, it serves as a release agent in rubber and paper production, facilitating the effortless release of products from molds.

Pharmaceutical Use

In the pharmaceutical industry, calcium stearate performs critical functions as a lubricant and an anti-caking agent. It is instrumental in tablet manufacturing, ensuring the smooth ejection of tablets from molds and preventing sticking. It is typically used at concentrations ranging from 0.5 to 2.0% of the formulation.

Food Industry Applications

Calcium stearate is recognized as a safe food additive, often utilized as an anti-caking agent and emulsifier. It contributes to the free-flowing nature of spices and powdered products. Regulatory bodies such as the FDA have approved its use within specific limits, generally not exceeding 2% in final food products.
