Description

C12-14-Alkyldimethyl(Ethylbenzyl)Ammonium Chloride is a high-purity quaternary ammonium compound (quat) widely valued for its potent antimicrobial and surfactant properties. This versatile chemical is essential for formulating effective disinfectants, sanitizers, and industrial biocides that require broad-spectrum efficacy and stability. It is a critical raw material for manufacturers in the hygiene, institutional cleaning, water treatment, and oilfield chemical industries seeking reliable, high-performance active ingredients.

Application

• Disinfectant & Sanitizer Formulations: A key active ingredient in hospital-grade disinfectants, surface cleaners, food contact sanitizers, and algaecides.
• Water Treatment: Used as a biocide and slimicide in industrial cooling towers, pulp and paper mills, and recreational water systems.
• Oilfield Chemicals: Employed as a bactericide in drilling fluids, fracturing fluids, and produced water treatment to control sulfate-reducing bacteria (SRB).
• Personal Care & Cosmetics: Functions as a preservative and conditioning agent in hair care products and certain rinse-off formulations.
• Textile & Leather Processing: Acts as a softener, antistatic agent, and biostatic finish for fabrics and hides.
• Industrial & Institutional (I&I) Cleaning: A component in floor cleaners, dairy cleaners, and other hard surface cleaners requiring disinfecting power.
