Sourcing Benzalkonium Chloride (BKC)? ChemicalDekho connects you with specialized surfactant manufacturers like Galaxy Surfactants and Hikal. Secure high-purity quaternary ammonium compounds (QUATs) for hygiene and water treatment.
BKC (CAS 8001-54-5) is the most widely used cationic surfactant for disinfection. It destroys the cell walls of bacteria, fungi, and algae. It is the active ingredient in non-alcohol hand sanitizers, floor cleaners (Lysol type), and swimming pool algicides. It is also used as a wood preservative and in aquaculture to treat water.
Listings usually feature BKC 50% (Standard) and BKC 80% (Concentrate). Pharma grade (IP/USP) is available for ophthalmic and topical formulations.

Causes severe skin burns and eye damage. Harmful if swallowed. Very toxic to aquatic life. Do not mix with anionic surfactants (Soap) as it deactivates.
50% is the standard commercial strength, easier to handle. 80% is a thick concentrate used by formulators who want to save on transport costs and dilute it themselves.
NO! Soap is Anionic (Negative charge). BKC is Cationic (Positive charge). If you mix them, they neutralize each other and form a useless white sludge.
Concentrated BKC is corrosive. Diluted (0.1% - 0.2%) is safe and used in hand sanitizers and wet wipes.
Yes, it is excellent for swimming pools. It kills green algae and prevents it from returning, often used alongside chlorine.
