Description

Zinc Bis[12-Hydroxyoctadecanoate] is a metal soap derived from 12-hydroxystearic acid, functioning as a versatile multi-purpose additive. This compound is valued for its ability to act as a stabilizer, thickener, and lubricant in various formulations, enhancing product performance and shelf life. It is primarily needed by manufacturers in the plastics, rubber, coatings, and personal care industries seeking to improve the rheological and thermal properties of their products.

Application

• PVC Stabilizer & Lubricant: Acts as a highly effective heat stabilizer and internal/external lubricant in rigid and flexible PVC formulations, improving processing and product clarity.
• Rubber Industry: Used as a processing aid and release agent in rubber compounding, facilitating mold release and reducing sticking.
• Grease & Lubricant Thickener: Serves as a gelling agent and thickener in the production of lithium complex and other specialty greases, providing excellent water resistance and stability.
• Coatings & Inks: Functions as a flatting and matting agent, as well as a rheology modifier, to control gloss and prevent sagging in paints and printing inks.
• Cosmetics & Personal Care: Employed as a viscosity modifier, emulsion stabilizer, and opacifying agent in creams, lotions, and deodorant sticks.
• Polymer Processing Aid: Enhances the dispersion of pigments and fillers in polymer melts, improving color distribution and reducing processing defects.

Quality Control

Our Zinc Bis[12-Hydroxyoctadecanoate] is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. Quality is verified through comprehensive analytical testing, including assay, metal content, and impurity profile analysis. A Certificate of Analysis (COA) detailing purity, physical characteristics, and compliance with agreed specifications 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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
