BKC 50% / 80% (Benzalkonium Chloride)
Cationic quaternary ammonium microbicide with dual biocidal and surfactant properties. Effectively lyses microbial cell membranes and strips stubborn green and blue-green algae films in cooling towers and swimming pools.
Technical Specification Target
Algae Lysis & Bio-dispersancy
BKC adsorbs rapidly onto negatively charged cell membranes of green and blue-green algae, disrupting the semi-permeable lipid bilayer and causing cell death within 4 to 8 hours of shock application.
Its wetting and surfactant action strips old dead slime patches from cooling tower timber and PVC fills, ensuring clean heat exchange surfaces.

Frequently Asked Questions: BKC 50% / 80% (Benzalkonium Chloride)
Expert technical answers on dosing, chemistry, handling, and application performance.
Q1. What is Benzalkonium Chloride (BKC 50% / 80%) and how does it act?
BKC (CAS 8001-54-5) is a cationic quaternary ammonium surfactant biocide that penetrates and destabilizes microbial cell membranes, eradicating green, black, and mustard algae and bacterial slime.
Q2. What is the recommended dosage of BKC in cooling towers and pools?
For cooling tower shock slug dosing, apply 20.0 to 80.0 ppm active. For swimming pool preventative algae control, 5.0 to 10.0 ppm weekly is standard.
Q3. What grades and concentrations of BKC does ZEEL PRODUCT manufacture?
ZEEL PRODUCT manufactures both BKC 50% aqueous solution and BKC 80% concentrated alcoholic/aqueous grades.
