FAQs – Benzalkonium Chloride :


Q1: What is Didecyl dimethyl ammonium chloride and how does it work?


A: Didecyl dimethyl ammonium chloride (CAS 7173-51-5), SINOSURF® DDAC, is a powerful twin-chain quaternary ammonium biocide. Unlike single-chain disinfectants, its double-hydrophobic carbon chains allow it to disrupt cell membranes of microorganisms much more aggressively. This unique structure makes it a top-tier disinfectant raw material globally.


Q2: What are the main common uses of DDAC in the chemical industry?


A: Its main uses focus on heavy-duty industrial defense. In water treatment, it kills algae and bio-slimes in cooling towers. In wood protection, it prevents outdoor logs and lumber from molding or rotting. In commercial cleaning, it acts as the primary active ingredient for concentrated agricultural and institutional sanitizers.


Q3: Where can I get live wholesale prices and samples for CAS 7173-51-5?
