Caprylisononyldimethylammonium chloride

Caprylisononyldimethylammonium chloride (CAS 138698-36-9), commercially known as Bardac 2170 and Bardac 21, is a quaternary ammonium compound used as an active biocidal ingredient.

Its cationic charge enables strong adsorption onto negatively charged surfaces, supporting both antimicrobial performance and soil removal in formulated products across industrial and institutional cleaning markets.

In home care and institutional cleaning, it functions as the active quat in disinfectant concentrates, hard surface sanitizers, and no-rinse floor cleaners where microbial control is required.

Personal care formulators incorporate it into conditioning rinses and leave-on treatments where surface deposition on hair or skin is the target outcome for the final consumer product.

Textile and leather processors use it as a softening and antistatic agent applied during finishing stages to modify surface feel and reduce static charge buildup on various materials.

In paper manufacturing, it supports surface sizing and wet-end chemistry where cationic charge aids fiber retention and surface treatment adhesion during the production process.

The material is supplied as an aqueous solution, with Bardac 2170 representing a 70% active concentrate. Technical grade is the standard offering for industrial formulation volumes.

Supply quantities range from drums to IBC totes suited to large scale manufacturing. This chemical ensures high performance in diverse applications requiring surface-active properties.
