Description

Diisooctadecyldimethylammonium Chloride is a high-purity, dialkyl quaternary ammonium salt valued for its excellent cationic surfactant properties and stability. This compound is essential for formulating products requiring strong emulsification, antistatic effects, and surface modification. It is a critical raw material for manufacturers in the personal care, textile, industrial cleaning, and polymer processing sectors seeking reliable performance and consistent quality.

Application

• Fabric Softeners & Textile Auxiliaries: Primary cationic agent for imparting softness, antistatic properties, and lubricity to fibers and fabrics.
• Hair Conditioners & Personal Care: Key ingredient in rinse-off conditioners and cream rinses for detangling, smoothness, and manageability.
• Industrial & Institutional Cleaners: Used as an emulsifier, dispersant, and sanitizing agent in hard surface cleaners and disinfectant formulations.
• Asphalt & Bitumen Emulsions: Acts as a cationic emulsifier to stabilize asphalt emulsions for road construction and maintenance.
• Paper & Pulp Processing: Employed as a retention aid, drainage aid, and softening agent in paper manufacturing.
• Mineral Processing & Ore Flotation: Serves as a collector and frothing agent in the flotation separation of minerals.
• Polymer & Rubber Additives: Functions as an internal/external antistatic agent and processing aid for plastics and synthetic rubbers.
• Agricultural Adjuvants: Used in pesticide and herbicide formulations to enhance spreading, adhesion, and penetration on plant surfaces.

Quality Control

Our Diisooctadecyldimethylammonium Chloride is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, composition, and performance. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed parameters. We support our global clients with documentation relevant to REACH, GMP, and ISO 9001 standards as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality. Keep away from strong oxidizing agents.
