Description

Bisarachidic Acid Zinc Salt is a specialized metal soap compound, also known as zinc behenate, valued for its role as a versatile lubricant and release agent. Its primary commercial significance lies in its ability to provide excellent slip and anti-blocking properties in polymer processing and coating applications. This product is essential for manufacturers in the plastics, rubber, and personal care industries seeking to improve product performance and processing efficiency.

Application

• Polymer Additive: Acts as an internal and external lubricant and release agent in PVC, polyolefins, and engineering plastics to enhance flow and prevent sticking during molding and extrusion.
• Rubber Industry: Used as a processing aid and dusting agent to improve mold release and surface finish in rubber products.
• Cosmetics & Personal Care: Functions as a texture enhancer, opacifier, and viscosity modifier in products like powders, creams, and stick formulations (e.g., deodorants).
• Coatings & Inks: Serves as a flatting and sanding agent to improve the matting and smoothness of surface coatings and printing inks.
• Pharmaceuticals: Employed as a tablet and capsule lubricant to ensure efficient manufacturing and consistent drug release profiles.
• General Industry: Used as a water-repellent agent and stabilizer in various industrial formulations.

Quality Control

Our Bisarachidic Acid Zinc Salt is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, metal content, and physical properties. Certificates of Analysis (COA) are provided with every shipment, documenting compliance with agreed-upon standards. We support customer-specific quality requirements and can provide material tailored to industrial, cosmetic, or pharmaceutical grade specifications upon request.

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 affect product performance.
