Benzalkonium chloride is a member of the quaternary ammonium class of biocides, recognised for its dual biocidal and detergency properties. Its biocidal efficacy depends on its capacity to act as a cationic surfactant in binding to and disrupting cellular and intracellular membranes, and associated biochemical processes. Functions such as cell adhesion, cell signaling, selective permeability to ions and nutritional organic molecules ensure cellular survival through its ability to interact with and respond effectively to environmental stimuli. Disruption of these processes ensures a high level of activity against bacteria, algae, fungi and enveloped viruses at exceptionally low concentrations. BC50 passes stringent BS EN 1276 microbicidal testing (high organic contamination, hard water conditions) at a dilution of 1:1250, giving a 5-log kill (1:100,000 bacterial survival) against a range of the most problematic organisms.

For very heavily coverd areas use a dilution rate of 1:20. For lightly covered areas use 1:40. It is very effective and economic. ## Frequently Bought Together - BAC 50 Benzalkonium Chloride 50% – Powerful Algaecide & Fungicide – Removes Algae, Moss & Bacteria – Industrial-Strength Biocide for Hard Surfaces, Pools & Water Treatment – 5 Litres (5L) - Spear & Jackson 5LPAPS 5 Litre Pump Action Pressure Sprayer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/229801076-bac-50-benzalkonium-chloride-50-powerful-algaecide-and-fungicide-removes](https://www.desertcart.vn/products/229801076-bac-50-benzalkonium-chloride-50-powerful-algaecide-and-fungicide-removes) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-15*
