Description

Sodium Isooctadecanoate is a versatile sodium salt of a branched-chain fatty acid, valued for its surfactant and emulsifying properties. This compound is essential for creating stable formulations and modifying surface characteristics in various industrial processes. It is particularly sought after by manufacturers in the personal care, lubricant, and polymer industries for its performance as a soap, thickener, and processing aid.

Application

• Personal Care & Cosmetics: Acts as a primary surfactant and emulsifier in soaps, creams, lotions, and shaving products.
• Industrial Lubricants & Greases: Functions as a thickening agent and soap base in calcium and lithium complex greases.
• Polymer & Plastic Additives: Serves as an internal or external lubricant and processing aid in PVC and other polymer formulations.
• Textile Processing: Used as a softening agent, lubricant, and anti-static agent in fiber production and fabric treatment.
• Metalworking Fluids: Employed as a corrosion inhibitor and emulsifier in synthetic and semi-synthetic cutting and grinding fluids.
• Detergents & Cleaning Agents: Provides cleaning and foaming properties in industrial and institutional cleaning formulations.

Quality Control

Our Sodium Isooctadecanoate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, identification, and impurity profile analysis. A Certificate of Analysis (COA) documenting all critical parameters is provided with every shipment to support your quality assurance protocols.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance.
