Manufacturers, Exporters and Suppliers of DDAC 80% – Didecyl Dimethyl Ammonium Chloride for Broad-Spectrum Disinfection & Water Treatment in Bihar

Innova Corporate (India) supplies DDAC (Didecyl Dimethyl Ammonium Chloride) – a high-performance quaternary ammonium compound (quat) offered as an 80% active concentrate, specifically for Bihar's industrial sanitization and algaecide applications. DDAC is a dialkyl quat with two decyl (C10) chains, giving it stronger biocidal activity than conventional benzalkonium chloride (BKC), particularly against fungi, biofilms, and algae. For Bihar's cooling towers – which face severe algal growth during monsoon (June-September, high humidity) and biofilm issues year-round – DDAC provides long-lasting control at 2-5 ppm continuous or 10-20 ppm shock dose. It also acts as a slime dispersant by breaking down EPS matrix, making it synergistic with other biocides. For sugar mills, DDAC is used as a sanitizer for evaporator surfaces and juice storage tanks (200-400 ppm) to prevent microbial growth that causes sugar inversion. For rice mills and food processing, it is used as a sanitizer for equipment and floors – effective against bacteria, yeast, and mold. For textile and handloom units, DDAC is used as a bacteriostat in fabric finishing (e.g., antimicrobial fabrics). The product is very stable in storage (2+ years) and has low volatility. It is compatible with non-ionic surfactants but incompatible with anionic polymers (like polyacrylates, lignosulfonates) – they will form precipitates. The product is biodegradable (60% in 28 days) but toxic to fish – do not discharge undiluted; send to CETP where dilution and biological degradation occur. For dairy and fruit processing units, we offer a food-grade DDAC formulation with NSF certification for indirect food contact. Supplied as an 80% active liquid (viscous, pale yellow), it must be diluted before use (forms a clear solution at 5-10% dilution). For cooling tower dosing, we recommend a diluted stock solution (10-20%) fed via metering pump. Available in 200L drums and 25L carboys. We also provide blends of DDAC with glutaraldehyde (e.g., 10% DDAC + 20% glutaraldehyde) for enhanced biofilm control in Bihar's industrial cooling loops – the blend is synergistic because glutaraldehyde kills rapidly while DDAC provides residual film and penetrates biofilm. Technical support includes quat test strips (for DDAC/BKC) and on-site compatibility testing.
