Cetalkonium chloride

Cetalkonium chloride (CAS 122-18-9), also known as CKC and commercially as Banicol, is a quaternary ammonium compound used across pharmaceutical, personal care, and industrial sectors. Its cationic character enables it to bind to negatively charged surfaces. This chemical acts as a broad-spectrum antimicrobial and surface-active agent, making it effective for both preservation and surface modification applications. In ophthalmic and topical pharmaceutical formulations, CKC functions as a preservative at low concentrations.

It is essential for preventing microbial contamination in multi-dose products. Personal care manufacturers incorporate it into hair conditioning products and rinse-off treatments where it imparts antistatic properties and improves wet combability. By adsorbing onto hair fiber surfaces, it enhances the overall texture and manageability of the hair. Textile and leather processors use it as a softening and finishing agent, modifying surface feel and providing durable antimicrobial protection.

In paper manufacturing, it supports wet-end chemistry as a biocidal additive to control microbial growth in process water and slurries. This ensures the integrity of the production process and the quality of the final paper products. Cetalkonium chloride is supplied as an aqueous solution, typically at concentrations of 25% or 50% active content. Technical and pharmaceutical-grade material is available to meet the quality requirements of industrial and regulated end-use markets.

Buyers should confirm purity specifications and counterion content when sourcing for pharmaceutical or personal care applications. Ensuring the correct grade is vital for maintaining safety and efficacy in sensitive consumer formulations.
