C12-14-alkyldimethyl(ethylbenzyl)ammonium chloride

C12-14-alkyldimethyl(ethylbenzyl)ammonium chloride (CAS 85409-23-0), also recognized commercially as alkylbenzyldimethylammonium chloride, is a quaternary ammonium compound used as a broad-spectrum biocide.

Its antimicrobial action and surface-active behavior make it a functional ingredient in disinfection, preservation, and cleaning formulations across industrial and institutional markets.

In home care and industrial cleaning, it is formulated into hard surface disinfectants, sanitizers, and institutional cleaners where both microbial kill and detergency are required in a single active.

Water treatment operations use it to control microbial growth in cooling towers, industrial water systems, and process water circuits to ensure operational efficiency and safety.

Personal care manufacturers incorporate it into preservative systems for rinse-off and leave-on products where low-level antimicrobial protection is needed for product stability.

It also functions as an emulsifying and dispersing agent in formulations requiring stable delivery of active ingredients across varied pH conditions and chemical environments.

The product is supplied as an aqueous solution, typically at concentrations of 50% or 80% active content. Technical grade is the standard commercial offering for these applications.

Supply specifications are aligned to industrial and institutional end-use requirements. Bulk liquid supply in IBCs and drums is the norm for large-volume procurement and logistics.
