What is BKC (Benzalkonium Chloride)?
BKC (Benzalkonium Chloride) is a quaternary ammonium compound (quat) widely used as a broad-spectrum antimicrobial and disinfectant agent. It is a cationic surfactant that disrupts microbial cell membranes, providing effective antibacterial, antifungal, and antiviral activity. BKC is supplied as an aqueous solution at varying active concentrations, with 50% and 80% being among the most common commercial grades used as concentrates for dilution into finished disinfectant and sanitiser products.
Polychem Industries supplies BKC in both 50% and 80% active concentrations to disinfectant manufacturers, sanitiser producers, agricultural companies, and water treatment facilities across India and internationally. Its proven antimicrobial efficacy, combined with good stability and compatibility with various formulation types, makes it one of the most widely used active ingredients in the global disinfectant and sanitation industry.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| BKC 50% (Technical/Industrial Grade) | Colourless to pale yellow liquid | 50% active / 80% active (w/w) | Industrial / Disinfectant | Surface disinfectants, sanitisers, agriculture, water treatment |
| BKC 80% (Concentrate Grade) | Colourless to pale yellow viscous liquid | 80% active | Industrial / Disinfectant | Concentrated disinfectant formulations, dilution-ready stock |
Applications & Uses
Hand Sanitisers & Surface Disinfectants
One of the most significant applications. BKC is used as the active antimicrobial ingredient in hand sanitisers, surface disinfectant sprays, and wipes, providing effective broad-spectrum antimicrobial action against bacteria, fungi, and certain viruses.
Healthcare & Institutional Disinfection
Used in hospital-grade disinfectants and institutional cleaning products for disinfecting surfaces, equipment, and instruments in healthcare, hospitality, and food service environments where stringent hygiene standards are required.
Agricultural & Veterinary Applications
Used as a disinfectant in agricultural settings including livestock facilities, poultry housing, and farm equipment sanitation, helping control pathogen spread and maintain biosecurity in animal production environments.
Water Treatment
Used as a biocide in certain water treatment applications including cooling tower water treatment and other industrial water systems to control microbial growth and biofilm formation.
Household & Institutional Cleaning Products
Used as the active disinfecting ingredient in household and institutional hard-surface cleaners, toilet cleaners, and multi-purpose disinfectant cleaning products.
Swimming Pool & Recreational Water
Used in certain recreational water treatment applications as an algaecide and biocide, helping control microbial and algal growth in swimming pools and other recreational water facilities.
