Description

Fatty Acids, Tallow, Guerbet Reaction Products, Sodium Salts are a specialized class of anionic surfactants derived from the Guerbet reaction of tallow fatty acids. This synthesis yields highly branched, high molecular weight sodium carboxylates, which are valued for their excellent emulsifying, wetting, and lubricating properties. These salts are particularly sought after by formulators in the personal care, industrial lubricant, and textile processing industries for creating stable, high-performance products. Their unique branched-chain structure provides superior solubility and surface activity compared to their linear counterparts.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and surfactant in creams, lotions, and hair conditioners, providing rich texture and stability.
• Industrial Lubricants & Metalworking Fluids: Serves as an effective emulsifier and corrosion inhibitor in soluble oils and synthetic coolants.
• Textile Processing: Used as a lubricant, softener, and anti-static agent in fiber spinning and fabric finishing.
• Leather Processing: Functions as a fatliquoring agent to soften and waterproof leather.
• Paint & Coating Additives: Employed as a dispersing and wetting agent for pigments and fillers.
• Agricultural Adjuvants: Enhances the spreading and adhesion of pesticides and herbicides on plant surfaces.

Quality Control

Our Fatty Acids, Tallow, Guerbet Reaction Products, Sodium Salts are manufactured under a strict quality management system. Each batch is tested to ensure consistent performance and meets specifications for key parameters such as active matter content, free fatty acid/alkali, moisture, and ionic character. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance with your formulation requirements.

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 container tightly sealed when not in use to prevent caking or absorption of atmospheric moisture. Keep away from strong acids.
