Description

Benzyl(Hexadecyl)Dimethylammonium α-Phenyl-p-Cresolate CAS NO 85851-69-0 is a quaternary ammonium compound with a cresolate counterion, representing a specialized class of cationic surfactants and antimicrobial agents. This unique structure provides a powerful combination of surface activity and biocidal efficacy, making it a critical functional ingredient in demanding industrial and institutional formulations. It is primarily utilized by manufacturers in the disinfectant, preservative, and specialty chemical sectors seeking high-performance, broad-spectrum antimicrobial activity.

Application

• Industrial and Institutional (I&I) Disinfectants & Sanitizers: A key active ingredient in formulations for hard surface disinfection in healthcare, food processing, and commercial facilities.
• Algaecides and Biocides for Cooling Water Systems: Used to control microbial growth, biofilm formation, and algae in industrial water cooling towers and recirculating systems.
• Wood Preservatives and Fungicides: Provides protection against mold, mildew, and wood-decaying fungi in treated lumber and composite materials.
• Oilfield and Drilling Fluid Additives: Acts as a biocide to prevent bacterial contamination and souring in drilling muds and production fluids.
• Textile and Leather Processing: Serves as a preservative and antimicrobial treatment for fibers, fabrics, and hides during manufacturing and storage.
• Paint and Coating Preservatives: Incorporated into water-based formulations to provide in-can preservation against spoilage microorganisms.
