Benzalkonium Chloride (BKC/BAC/BAK)


What is Benzalkonium Chloride?

Benzalkonium Chloride is a powerful antiseptic and a cationic surfactant. Benzalkonium Chloride is also known as BZK, BKC, BAK, alkyl dimethyl benzyl ammonium chloride and ADBAC.

Our FeF Benzalkonium Chloride products have proven efficacy against a broad spectrum of microorganisms (gram + and – & acid fast bacteria, yeasts, moulds and enveloped vira such as HIV, herpes and corona). They are effective through a wide pH range, are surface active/adhesive cationic agents and do not add unpleasant odour/colour to finished formulations.
