Description

Calcium Stearate Powder CAS NO 8000-75-7 is a fine, white, free-flowing powder widely recognized as a versatile metallic soap and lubricant. Its primary value lies in its excellent water-repellent, lubricating, and release properties, making it a critical processing aid and functional additive. This compound is essential for manufacturers in the plastics, rubber, pharmaceutical, food, and construction industries seeking to improve product flow, prevent sticking, and enhance stability.

Application

• Plastics & Polymers: Acts as an acid scavenger, lubricant, and release agent in PVC, polyolefins, and engineering plastics to improve processing and surface finish.
• Rubber Industry: Used as a dusting agent, mold release agent, and processing aid to prevent adhesion during calendering and extrusion.
• Pharmaceuticals & Cosmetics: Serves as a tablet and powder lubricant, glidant, and anti-caking agent in solid dosage forms and cosmetic powders.
• Food Industry (FCC Grade): Functions as an anti-caking agent, emulsifier, and binder in food powders, confectionery, and food supplements.
• Construction Materials: Imparts water repellency and workability in concrete, cement, and gypsum plaster formulations.
• Paints & Coatings: Used as a flatting agent and suspending aid to control gloss and prevent pigment settling.
• Paper Production: Employed as a lubricant and sizing agent to improve paper smoothness and water resistance.
• Personal Care: Functions in pressed powders, deodorants, and soaps as a binder and texture enhancer.

Quality Control

Our Calcium Stearate Powder is manufactured under strict quality management systems. Each batch is tested to ensure it meets specifications for key parameters such as calcium content, free fatty acids, moisture, and particle size distribution. We offer grades compliant with Food Chemicals Codex (FCC), National Formulary (NF), and other relevant industrial standards. A Certificate of Analysis (COA) is provided with every shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to atmospheric moisture. Keep away from strong acids and oxidizing agents.
