Description

Diisodecyldimethylammonium Chloride is a quaternary ammonium compound (quat) valued for its potent antimicrobial and surfactant properties. This chemical is a key ingredient in the formulation of disinfectants, sanitizers, and fabric softeners, offering excellent biocidal efficacy and surface activity. It is essential for manufacturers in the hygiene, water treatment, textile, and oilfield chemical industries seeking reliable and effective cationic agents.

Application

• Primary active ingredient in industrial and institutional disinfectants and sanitizers.
• Fabric softener and antistatic agent in textile and laundry care formulations.
• Biocide and algicide in industrial water treatment and cooling tower systems.
• Emulsifier and phase transfer catalyst in specialty chemical synthesis.
• Additive in oilfield chemicals for its corrosion inhibition and biocidal properties.
• Component in wood preservatives and antimicrobial coatings.
