Description

(Ethylbenzyl)Dimethyloctadecylammonium Chloride is a high-purity quaternary ammonium compound (quat) valued for its potent cationic surfactant and antimicrobial properties. This chemical is essential for formulators requiring a stable, long-chain benzyl quat with excellent surface activity and broad-spectrum efficacy. It serves as a critical raw material for manufacturers in the disinfectant, biocide, and specialty surfactant industries, where performance and supply chain reliability are paramount.

Application

• Disinfectant & Sanitizer Formulations: A key active ingredient in industrial, institutional, and agricultural disinfectants effective against bacteria, viruses, and fungi.
• Algaecides and Biocides: Used in water treatment systems, cooling towers, and recreational water to control microbial and algal growth.
• Fabric Softeners and Conditioners: Acts as a cationic softener, providing antistatic and softening properties to textiles.
• Personal Care Preservatives: Employed as a preservative agent in cosmetics and toiletries due to its antimicrobial action.
• Phase Transfer Catalyst: Facilitates reactions between reactants in immiscible phases in organic synthesis.
• Wood and Material Preservatives: Imparts antimicrobial protection to treated wood, paints, and coatings.
• Oilfield Chemicals: Used in drilling muds and completion fluids for its biocidal and surfactant properties.
