Properties:
Diotyl Dimethyl Ammonium Chloride (DDAC) is a twin-chain quaternary ammonium compound that provides controlled foam biocidal action. It has been found to exhibit low, fast-breaking foam with exceptional dynamic, controlled foam performance in FIFRA1-registered hard surface disinfectants, sanitizers, and certain types of water treatment formulations. DDAC delivers potent germicidal action against a broad spectrum of microbial organisms, including bacteria, fungi, viruses, and algae, even under heavy organic soil loads and complex water conditions.
Usage:
Diotyl Dimethyl Ammonium Chloride (DDAC) is a quaternary ammonium-based antimicrobial used as a bacteriostat, disinfectant, or micro biocide. It is ideal for recirculation water systems where control of undesirable microbes without excessive foam is essential.
DDAC has been found to be effective in a variety of fields, including injection water treatment in oilfields and industrial circulating cooling systems, fungi, and bacteria disinfection, wood preservative agents, and textile moth-proofing agents. Additionally, it can also be used with chlorine dioxide when treating hard surfaces to eliminate bacteria.
Package and Storage:
Diotyl Dimethyl Ammonium Chloride (DDAC, D0821) should be stored in original containers in a dry and well-ventilated area away from extreme temperatures. It is recommended to keep the product sealed and out of direct sunlight as high temperatures can degrade its efficacy. When handling DDAC, protective clothing such as gloves, face shields, respirators, boots, and chemical-resistant aprons are recommended.200L plastic drum, IBC(1000L), customers’ requirement—storage for one year in a shady room and dry place.
