Description

Hexamethyloctamethylenebisammoniumchloride is a quaternary ammonium compound (QAC) with a long-chain alkyl structure, valued for its potent cationic surfactant properties. This chemical is a highly effective biocide and phase transfer catalyst, offering superior performance in formulations requiring antimicrobial action and surface activity. It is essential for manufacturers in the water treatment, personal care, textile processing, and oilfield chemical industries seeking reliable and efficient active ingredients.

Application

• Industrial Biocide & Disinfectant: A key active ingredient in formulations for cooling water systems, paper mills, and surface disinfectants.
• Personal Care Preservative: Used in shampoos, conditioners, and lotions to inhibit microbial growth and extend product shelf life.
• Textile Softener & Antimicrobial Agent: Imparts a soft hand feel and provides durable antimicrobial protection to fabrics.
• Oilfield Chemicals: Functions as a bactericide in drilling fluids and production systems to control sulfate-reducing bacteria (SRB).
• Phase Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases in organic synthesis.
• Algaecide & Slimicide: Effective in controlling algal and slime formation in industrial water circuits and recreational water.
