Description

Dihexadecyl Dimethyl Ammonium Chloride is a high-purity, dialkyl quaternary ammonium compound 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 serves as a critical raw material for manufacturers in the personal care, textile, and industrial biocides sectors seeking reliable performance and supply chain consistency.

Application

• Primary emulsifier and softener in fabric conditioners and textile auxiliaries.
• Key cationic surfactant in hair conditioners and cream rinses for the personal care industry.
• Antistatic agent for plastics and synthetic fibers.
• Emulsifier and dispersant in industrial and institutional cleaning formulations.
• Intermediate for the synthesis of other specialty quaternary ammonium compounds.
• Component in organoclay production for oil-based drilling fluids and paints.
• Biocide and preservative in select industrial water treatment applications.
