DDAC (Didecyl Dimethyl Ammonium Chloride) is a cationic surfactant and non-oxidizing biocide offering broad-spectrum microbial control in both industrial and institutional environments. It kills microorganisms by disrupting their cell membranes and denaturing proteins. DDAC is stable over a wide range of pH and temperatures, and it is especially effective in environments where continuous protection is needed. Its low-foaming nature and compatibility with hard water make it ideal for surface disinfection, biofilm control, and formulation into multipurpose disinfectants.
Rapid Broad-Spectrum Action – Eliminates bacteria, fungi, viruses, and algae
Long Residual Activity – Maintains microbial control even after drying
Low Toxicity & Non-Corrosive – Safe on metals, plastics, and rubber
Hard Water Tolerant – Performs well in presence of salts and organic loads
Low-Foaming Profile – Suitable for spray, soak, and CIP applications
pH & Temperature Stable – Effective across wide environmental conditions
Healthcare & Sanitation – Surface and equipment disinfection in hospitals and clinics
Food & Beverage Industry – Sanitization of processing areas, utensils, and pipelines
Livestock & Poultry Hygiene – Disinfection of farms, hatcheries, and dairy operations
Water Treatment – Biofilm and algae control in industrial and commercial systems
Agricultural Sprays – Used in greenhouse and post-harvest disinfection
Cleaners & Disinfectant Formulations – Key ingredient in multipurpose biocidal products
