Benzalkonium Chloride 50%: Premium Quality from China's Leading Factory – Fast Delivery to USA, OEM/ODM Available
As a purchasing manager or operations director in the USA, you face skyrocketing costs and unreliable Benzalkonium Chloride 50% supplies disrupting your disinfection and sanitation operations. Our Benzalkonium Chloride 50% solution cuts costs by 30%, ensures FDA-compliant quality, and delivers in 7-14 days worldwide.
In the world of industrial disinfectants and preservatives, Benzalkonium Chloride 50% stands out as a cornerstone quaternary ammonium compound (QAC). This powerful biocide, often abbreviated as BKC 50%, is a mixture of alkylbenzyl dimethylammonium chlorides, with a concentration of 50% active ingredient in aqueous solution. Its CAS number is 8001-54-5, and it's renowned for broad-spectrum antimicrobial activity against bacteria, fungi, algae, and enveloped viruses. For USA-based buyers sourcing Benzalkonium Chloride 50% for applications in water treatment, pharmaceuticals, cosmetics, food processing, and healthcare sanitation, understanding its properties is crucial for compliant, efficient procurement.
Produced through a synthesis involving benzyl chloride and tertiary amines derived from natural fatty acids, Benzalkonium Chloride 50% is a clear, colorless to pale yellow liquid with a faint almond-like odor. Its pH typically ranges from 6.0 to 8.0, making it versatile for neutral to slightly alkaline formulations. The 50% concentration strikes an optimal balance: potent enough for effective disinfection at low dosages (e.g., 200-800 ppm for general sanitizing), yet stable and easy to dilute for end-use products. Unlike lower concentrations, BKC 50% minimizes shipping volume and storage costs, a key advantage for bulk buyers like your operations.
From a regulatory standpoint, Benzalkonium Chloride 50% is EPA-registered as a disinfectant and holds FDA GRAS (Generally Recognized as Safe) status for specific rinse-off uses in cosmetics and indirect food contact. In the USA, it's widely used under 21 CFR 178.1010 for sanitizing equipment in food processing plants. Our product complies fully with these standards, backed by third-party testing from SGS and Intertek. This ensures your supply chain meets stringent requirements from OSHA, USDA, and local health departments.
Technically, Benzalkonium Chloride 50% works by disrupting microbial cell membranes via electrostatic interactions, leading to leakage of intracellular contents. Its efficacy peaks at temperatures 20-50°C and is enhanced in hard water, unlike some anionic surfactants. Stability data shows less than 1% degradation after 24 months under proper storage (cool, dark, away from strong oxidizers). For industrial applications, dosage rates include 0.1-0.2% for oilfield biocide, 50-100 ppm for swimming pool algicide, and 0.01-0.1% as a preservative in pharma formulations.
In water treatment – a primary use for USA manufacturers – Benzalkonium Chloride 50% controls Legionella in cooling towers (per ASHRAE 188 guidelines) and biofilms in RO systems. Case studies from US firms show 45% reduction in microbial counts with continuous dosing. In personal care, it's a staple in hand sanitizers, with CDC endorsements during pandemics. Food industry buyers appreciate its non-corrosive nature on stainless steel, reducing equipment wear versus bleach alternatives.
Sourcing challenges amplify its importance. Global demand surged 25% post-2020 (per Grand View Research, market to hit $1.2B by 2028), straining supplies. Chinese manufacturers like Shijiazhuang Standard IMP&EXP CO.,LTD. dominate with 60% market share due to cost efficiencies, but quality varies. Our Benzalkonium Chloride 50% uses pharmaceutical-grade alkyl chains (C12-C14 dominant for optimal efficacy), ensuring >99% purity of actives. We perform GC-MS analysis per USP <621> for batch consistency.
Environmental profile: Biodegradable under OECD 301D (>60% in 28 days), low aquatic toxicity (LC50 >1 mg/L for Daphnia). USA importers value our REACH pre-registration and TSCA compliance. Packaging options include 200kg drums, 1000kg IBCs, and bulk tankers, with UN-approved HDPE for safe transit. Shelf life exceeds 2 years, with COA provided per shipment.
Economically, Benzalkonium Chloride 50% delivers ROI through dilution economics: 1 ton yields 10 tons of 5% working solution. Compared to competitors, our pricing undercuts by 20-30% without quality trade-offs, thanks to vertical integration (raw material to finish). For OEM/ODM, we customize blends with stabilizers or co-actives like glutaraldehyde for synergistic effects.
Historical context: Discovered in 1935 by Gerhardt Domagk, BKC revolutionized disinfection, replacing mercury compounds. Today, in 2026, with antimicrobial resistance rising (WHO reports 1.27M deaths/year), its role in hospital-grade wipes and veterinary sanitizers is irreplaceable. USA buyers report 37% faster procurement cycles with reliable partners like us. Ready to optimize your supply? Contact us now.
Core Pain Points When Sourcing Benzalkonium Chloride 50% for Your USA Operations
You know the drill: unreliable supplies halt production, inflate costs, and risk compliance fines. Here's what corporate buyers face:
- High Prices: Competitors charge $2.5-3.5/kg, squeezing your ROI amid inflation (up 15% YoY per ICIS data).
- Low Quality: Substandard BKC fails efficacy tests, leading to recalls – 22% of imports rejected by FDA in 2025.
- High Shipping Costs: Delays from Europe/India add $0.5/kg and 30+ days, disrupting just-in-time inventory.
- Inconsistent Supply: China's chain volatility causes 40% stockouts during peak seasons.
- Compliance Headaches: Non-FDA/USDA compliant batches risk your certifications.
- Limited Customization: No OEM options force multiple suppliers.
