Description

N,n-Dimethyl-n-Octadecylbenzylammonium is a high-purity quaternary ammonium compound (QAC) widely recognized for its potent surfactant and antimicrobial properties. This versatile chemical is essential for formulating effective biocides, phase transfer catalysts, and cationic surfactants. It serves critical functions across the industrial, pharmaceutical, and personal care sectors, where reliable performance and consistent quality are paramount.

Application

• Industrial Biocide & Disinfectant: A key active ingredient in formulations for water treatment, surface sanitizers, and algicides.
• Phase Transfer Catalyst (PTC): Facilitates reactions between reactants in immiscible phases, crucial in organic synthesis and polymer manufacturing.
• Cationic Surfactant: Used in fabric softeners, hair conditioners, and antistatic agents due to its excellent substantivity to negatively charged surfaces.
• Emulsifier & Dispersant: Stabilizes emulsions and suspensions in agrochemicals, coatings, and specialty chemical preparations.
• Pharmaceutical Intermediate: Employed in the synthesis of certain antiseptic and preservative agents.
• Oilfield Chemical: Acts as a corrosion inhibitor and biocide in drilling and production fluids.
