Description

Zinc Palmitate is a white, fine powder belonging to the class of metallic soaps or carboxylates. This compound serves as a versatile and effective functional additive, primarily valued for its hydrophobic, lubricating, and stabilizing properties. It is a critical material for formulators and manufacturers in the plastics, personal care, and coatings industries seeking to improve product performance and processing characteristics.

Application

• Plastics & Polymer Processing: Acts as an internal/external lubricant and release agent in PVC, polyolefins, and engineering plastics to enhance flow, reduce sticking, and improve surface finish.
• Cosmetics & Personal Care: Used as a texture modifier, opacifying agent, and viscosity regulator in products like powders, foundations, and creams to provide a smooth, silky feel.
• Paints & Coatings: Functions as a flatting (matting) agent and sanding aid to reduce gloss and improve sandability in wood coatings and industrial finishes.
• Rubber Industry: Employed as a processing aid and mold release agent to facilitate mixing, extrusion, and demolding of rubber compounds.
• Pharmaceuticals: Utilized as a tablet and capsule lubricant to prevent sticking during the manufacturing process.
• Textile & Fiber: Serves as a water-repellent finish and softening agent for fabrics and non-woven materials.
• Grease & Lubricant Formulation: Acts as a thickener and stabilizer in specialty grease formulations.

Quality Control

Our Zinc Palmitate is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. We offer grades suitable for industrial, cosmetic, and pharmaceutical applications. Product quality is verified against stringent in-house specifications, and a Certificate of Analysis (COA) detailing key parameters such as assay, heavy metal content, and physical properties is provided with each 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 to prevent absorption of atmospheric moisture, which can lead to caking and performance degradation.
