Inquiry now Professional-grade dichlor chlorine granule formulations engineered for powerful surface disinfection across healthcare, food processing, hospitality, and industrial environments.
Dichlor chlorine granules — most commonly referring to Sodium Dichloroisocyanurate (SDIC) and Trichloroisocyanuric Acid (TCCA) — are highly effective chlorine-based disinfectants in granular form. When dissolved in water, they release active chlorine (HOCl) that rapidly destroys bacteria, viruses, fungi, and algae on contact.
These granules are prized for their high stability, ease of handling, long shelf life, and broad-spectrum antimicrobial activity. Unlike liquid chlorine, dichlor granules are non-corrosive to packaging, easy to measure, and safe to transport, making them the preferred choice for surface disinfection in commercial and industrial settings.
SDIC 56% granules release chlorine at a controlled rate, ideal for preparing disinfectant solutions for floor mopping, equipment wipe-downs, and surface spraying. TCCA 90% granules offer higher active chlorine content, suited for high-load disinfection tasks such as industrial plant sanitation, large-area surface treatment, and emergency epidemic control.
Compared to liquid bleach or powder formulations, dichlor chlorine granules offer several decisive advantages for surface disinfection applications. Their low moisture content ensures extended shelf life — typically 2–3 years when stored correctly — without significant loss of active chlorine. The granular form dissolves rapidly in water, allowing operators to prepare precise concentrations on-demand.
The pH-neutral to mildly acidic nature of SDIC solutions means they are gentler on treated surfaces compared to caustic soda-based disinfectants, reducing damage to floors, countertops, and equipment surfaces. In food-grade environments, this is a critical compliance requirement.
⚡ Key Performance Advantage: At a concentration of just 200–500 ppm active chlorine, SDIC granule solutions achieve >99.9% kill rates against common pathogens including E. coli, Salmonella, Norovirus, and MRSA within 30 seconds of contact — a benchmark that few competing disinfectants can match at equivalent cost.
From healthcare facilities to food factories, dichlor chlorine granules set the global benchmark for surface disinfection performance, safety, and cost-efficiency.

The global chlorine-based disinfectant market is experiencing robust growth, driven by heightened hygiene standards post-pandemic, stricter food safety regulations, and rapid expansion of healthcare infrastructure in emerging markets.
Post-Pandemic Hygiene Normalization: Since 2020, surface disinfection protocols have been permanently elevated across virtually every commercial sector. Hospitals, schools, offices, transit hubs, and retail spaces now maintain daily or multi-daily disinfection schedules that were previously reserved for outbreak scenarios. This structural shift has created sustained, predictable demand for bulk dichlor granules.
Food Safety Regulation Tightening: The FDA Food Safety Modernization Act (FSMA), EU Regulation 852/2004, and equivalent frameworks in Asia-Pacific now mandate documented surface disinfection programs for all food processing facilities. SDIC granules, with their food-safe profile and easy audit documentation, have become the default choice for HACCP-compliant operations.
Healthcare-Associated Infection (HAI) Prevention: HAIs affect approximately 1 in 31 hospitalized patients globally (WHO data). Surface disinfection with chlorine-releasing agents is a cornerstone of HAI prevention protocols endorsed by the CDC, WHO, and ECDC. Dichlor granules are widely specified in terminal cleaning and outbreak response procedures.
Automated Dilution & Dispensing Systems: Modern commercial kitchens, hospitals, and industrial plants increasingly deploy automated chemical dispensing systems. Dichlor granules are now formulated for compatibility with these systems, enabling touchless, precise preparation of disinfectant solutions at point-of-use.
Smart Disinfection Monitoring: IoT-enabled chlorine sensors are being integrated into surface disinfection workflows, allowing real-time verification that active chlorine concentrations meet target levels. Granule-based systems are particularly well-suited to this approach due to their consistent dissolution profiles.
Sustainable Packaging Innovations: Leading suppliers including Hebei Liuhe are transitioning to recyclable HDPE drums and biodegradable inner liners, responding to procurement policies that require suppliers to demonstrate reduced plastic waste and lower carbon footprints across the supply chain.
Customized Formulations: Buyers increasingly demand granules co-formulated with corrosion inhibitors, surfactants, or stabilizers for specific surface types — stainless steel, ceramic tile, food-contact plastics — driving growth in specialty dichlor products beyond standard SDIC and TCCA grades.
Dichlor chlorine granules serve as the disinfection backbone across a remarkably diverse range of commercial and industrial environments. Here we examine the most critical use cases in detail.
ICU floors, surgical suite surfaces, patient bed rails, and medical equipment contact points require disinfectants with verified virucidal and sporicidal activity. SDIC 56% granule solutions at 1,000 ppm are WHO-recommended for terminal cleaning of Clostridioides difficile-contaminated surfaces. Hospitals in Europe, the Middle East, and Southeast Asia rely on bulk SDIC granule supply for cost-effective infection control programs.
Slaughterhouses, seafood processing plants, dairy facilities, and ready-to-eat food manufacturers apply SDIC granule solutions to conveyor belts, cutting boards, processing tables, and drainage channels. The food-safe, non-tainting profile of SDIC at approved concentrations meets USDA, EU, and Codex Alimentarius requirements for food-contact surface sanitizers.
High-touch surfaces — door handles, desks, restroom fixtures, playground equipment — in schools and public buildings are primary vectors for respiratory and gastrointestinal illness transmission. Pre-dissolved SDIC granule solutions (200–500 ppm) are safe for routine use on these surfaces, providing effective protection without harsh residues that could affect children or sensitive occupants.
Hotels, cruise ships, airports, and convention centers require disinfection at scale. TCCA 90% granules offer the highest active chlorine density, reducing storage space requirements for large facilities. Professional cleaning contractors increasingly specify granule-based systems over liquid bleach for their superior shelf life, reduced VOC emissions, and easier staff handling.
Animal housing surfaces, milking equipment, and veterinary clinic floors must be disinfected to prevent zoonotic disease transmission and antibiotic resistance spread. TCCA 90% granules are approved for use in livestock environments and are highly effective against Foot-and-Mouth Disease Virus, Avian Influenza, and African Swine Fever Virus on hard surfaces.
Chemical plants, pharmaceutical manufacturing cleanrooms, and electronics assembly facilities use dichlor granule solutions for periodic deep disinfection of floors, walls, and non-product-contact equipment surfaces. The ability to achieve validated log-reduction kill rates is essential for GMP compliance and regulatory inspection readiness.
During disease outbreak events — cholera, Ebola, COVID-19 — health authorities deploy large quantities of SDIC granules for rapid, large-scale surface decontamination of affected buildings, vehicles, and public spaces. The ease of air-freight transport and rapid dissolution of granules makes them uniquely suited to emergency logistics scenarios.
Fish farm tanks, hatchery surfaces, boat hulls, and aquaculture equipment are treated with SDIC granule solutions to eliminate pathogenic bacteria and parasites. The residue-free profile after chlorine dissipation ensures no harm to aquatic organisms once treated surfaces are rinsed and re-introduced to the aquatic environment.
Airports, railway stations, bus terminals, and cargo warehouses require frequent surface disinfection of high-contact zones. Portable granule dosing kits enable cleaning teams to prepare fresh disinfectant solutions on-site without the need for pre-mixed liquid storage, reducing chemical waste and improving operational flexibility.
