Description

Calcium Palmitate CAS NO 542-42-7 is a white, fine powder classified as a metallic soap or calcium salt of palmitic acid. This compound serves as a highly effective and versatile multi-functional additive, primarily valued for its lubricating, stabilizing, and water-repellent properties. It is an essential material for manufacturers in the plastics, polymer, food, and pharmaceutical industries seeking to improve product performance and processing efficiency.

Application

• Plastics & Polymer Processing: Acts as an internal/external lubricant and acid scavenger (stabilizer) in PVC, polyolefins, and engineering plastics to enhance flow, prevent sticking, and improve surface finish.
• Food Industry Additive: Used as an anti-caking agent, emulsifier, and stabilizer (e.g., E470a) in powdered food products, dairy analogs, and edible coatings.
• Pharmaceutical & Cosmetic Formulations: Functions as a tablet lubricant, glidant, and hydrophobic agent in solid dosage forms, and as an opacifier or viscosity modifier in creams.
• Construction Materials: Imparts water repellency and workability as a hydrophobic agent in concrete, plasters, and cement-based products.
• Paper & Cardboard Coating: Serves as a lubricant and water-resistant sizing agent to improve machinability and moisture barrier properties.
• Textile & Fiber Treatment: Applied as a softening agent and water repellent finish for natural and synthetic fibers.
• Grease & Lubricant Thickener: Functions as a component in the formulation of certain calcium-based greases.
• Personal Care Products: Used in powders (e.g., talcum) as a binder and anti-caking agent.

Quality Control

Our Calcium Palmitate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and performance. We can supply material compliant with relevant standards such as FCC (Food Chemicals Codex) for food-grade applications. A comprehensive Certificate of Analysis (COA) documenting all critical parameters is provided with every shipment.

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 absorption of atmospheric moisture, which can lead to caking and reduced performance.
