Benzalkonium Chloride for Food & Beverage CIP / COP Sanitation
Benzalkonium Chloride (BKC) is a no-rinse food-contact sanitiser used in dairy plants, breweries, soft-drink bottlers and meat/poultry processors for clean-in-place (CIP) and clean-out-of-place (COP) cycles. Vasudev Chemo Pharma supplies BKC 50% and 80% grades for food-safety sanitiser formulators.

Food-contact limits and efficacy
For no-rinse food-contact surfaces, BKC is approved up to 200 ppm active quat under FDA 21 CFR 178.1010 — do not exceed this. Non-food-contact zones (drains, walls, equipment exteriors) typically use 1,000–2,000 ppm. BKC is effective against the main food pathogens: Listeria monocytogenes, Salmonella, E. coli O157:H7 and Pseudomonas spp.
Use in CIP sequences
BKC sanitising is applied after the alkaline (caustic) and acid CIP steps, commonly at 60–70 °C. It is compatible with typical alkaline CIP chemistries when dosed as a separate sanitising step. Blenders formulate from BKC 80% concentrate; verify hardness tolerance and use soft/demineralised water to maintain activity.
Frequently asked questions
What is the maximum BKC concentration for no-rinse food contact?+
200 ppm active quat under FDA 21 CFR 178.1010. Higher concentrations require a potable-water rinse or are limited to non-food-contact surfaces.
Which pathogens does BKC control in food plants?+
Listeria monocytogenes, Salmonella, E. coli O157:H7 and Pseudomonas species, among others.
Where does BKC fit in a CIP cycle?+
As the sanitising step after caustic and acid cleaning, typically at 60–70 °C, using soft or demineralised water.
