Calcium Stearate CAS 1592-23-0 Powder Granular Flake

Product Overview

Calcium Stearate is a high-performance organic metallic stearate widely utilized in global industrial production. With CAS 1592-23-0, it is commercially available in three standard forms including powder, granular andflake, matching diverse industrial processing and feeding requirements.

Full common aliases of Calcium Stearate include Calcium Octadecanoate, Calcium Distearate, Stearic Acid Calcium Salt, Octadecanoic Acid Calcium Salt, and food grade additive code E470a. This organic fatty acid calcium salt features stable chemical structure, excellent lubricity, anti-caking and thermal stabilization properties. It holds valid REACH registration for EU market compliance, and MSDS download is accessible for global trade clearance and industrial safety assessment.

Typical Product Specifications (Industrial Grade)

Below is the standard industrial grade index of Calcium Stearate, which is the most commonly used grade for bulk export and industrial processing:

Physical Properties & Characteristics

Calcium Stearate is an odorless, white solid with fine, smooth and waxy texture. It exhibits unique physical solubility characteristics, being insoluble in cold water and only slightly soluble in hot ethanol and partial organic solvents. The material possesses outstanding thermal stability, low volatility and excellent dispersion and water-repellent performance under conventional processing conditions. It undergoes chemical decomposition when exposed to strong acid, producing stearic acid and calcium salts. Classified as non-toxic and environmentally friendly, it ensures safe application across multiple industries. Variable physical forms of powder, granular and flake effectively reduce dust generation and enhance feeding stability for automated production lines.

Main Applications

Calcium Stearate is a multi-functional industrial additive extensively applied in plastic processing, rubber manufacturing, coating production, papermaking, cosmetics and food processing industries. It acts as a criticalheat stabilizer and internal lubricant for PVC and polymer materials, optimizing melt fluidity and inhibiting high-temperature material degradation during extrusion and molding processes. Serving as a high-efficiency mold release agent, it delivers smooth demolding effects and improves surface finish of finished products. As a reliable anti-caking agent, it maintains the loose state of powdered and granular industrial materials. Additionally, it functions as a flatting agent and water repellent in coating and paper industries, providing stable and efficient auxiliary effects for industrial manufacturing.
