Description

9,12-Octadecadienoic Acid (Z,Z)-, Dimer, Diammonium Salt is a high-purity, water-soluble ammonium salt derived from the dimerization of linoleic acid. This specialized chemical is valued for its excellent emulsifying, dispersing, and surface-active properties in demanding industrial formulations. It serves as a critical functional additive for manufacturers in the coatings, lubricants, and personal care industries seeking enhanced performance and stability.

Application

• Coatings & Inks: Acts as a highly effective dispersing and wetting agent for pigments and fillers in water-based systems, improving color development and stability.
• Metalworking Fluids: Functions as a key emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and lubricants.
• Personal Care & Cosmetics: Used as a mild surfactant and emulsifier in skin creams, lotions, and hair care products, providing stable emulsions.
• Textile Processing: Serves as a lubricant and softening agent in fiber processing and finishing baths.
• Adhesives & Sealants: Enhances the dispersion of components and improves the rheological properties of water-based adhesive formulations.
• Agricultural Formulations: Utilized as an emulsifier and adjuvant in pesticide and herbicide concentrates to improve sprayability and plant coverage.

Quality Control

Our production of 9,12-Octadecadienoic Acid (Z,Z)-, Dimer, Diammonium Salt adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure consistent purity, composition, and performance. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, amine value, acid value, and moisture content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
