Description

Octadecyl/Behenyl Dimethylamines is a high-purity tertiary amine blend, primarily composed of C18 and C22 alkyl dimethylamine homologues. This versatile chemical intermediate is valued for its role in synthesizing quaternary ammonium compounds (quats) and amine oxides, which are essential for creating effective surfactants and conditioning agents. It is a critical raw material for manufacturers in the personal care, home care, textile, and industrial surfactant sectors seeking to produce high-performance cationic formulations.

Application

• Surfactant Synthesis: Primary intermediate for the production of dialkyl dimethyl ammonium chloride (DADMAC) and other quaternary ammonium compounds used as fabric softeners, antistatic agents, and disinfectants.
• Personal Care Ingredients: Key precursor for manufacturing behentrimonium chloride and other conditioning agents in hair care products (conditioners, shampoos) and skin care formulations.
• Industrial & Institutional Cleaners: Used to synthesize cationic surfactants for car wash soaps, industrial cleaners, and sanitizers where surface activity and microbial control are required.
• Textile & Fiber Treatment: Imparts softness, lubricity, and antistatic properties to natural and synthetic fibers during processing.
• Oilfield Chemicals: Serves as a chemical building block for formulating corrosion inhibitors, demulsifiers, and other specialty additives.
• Asphalt & Road Chemicals: Used in the production of asphalt emulsifiers and adhesion promoters.
• Agricultural Adjuvants: Intermediate for creating cationic surfactants used in pesticide and herbicide formulations to improve adhesion and spreading.

Quality Control

Our Octadecyl/Behenyl Dimethylamines are manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance. Key parameters such as amine value, alkyl chain distribution, and color are monitored. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and acids. Under these conditions, the product has excellent shelf stability.
