Didecyldimethylammonium chloride (DDAC) is used for various purposes, such as a fungicide for coolants, an antiseptic for wood, and disinfectant for cleaning. Disinfectants are the chemical agents that either inhibit microbial activities and growth or are lethal and kill the microorganisms. In man’s struggle to control the microbes responsible for disease and illness many organic and inorganic chemicals have been found to be toxic to microorganisms.

Bardac® 22 Antimicrobials contain the active substance Didecyldimethyl ammonium chloride (DDAC). The active is a cationic molecule offering good surfactant properties and can be formulated to- gether with non- ionic and/or amphoteric surfactants. DDAC has a broad antimicrobial efficacy against gram-positive and gram-negative bacteria, yeast, and enveloped viruses. High antimicrobial efficacy is maintained even at low temperatures and in the presence of organic soil, such as blood and protein. In formulated products, DDAC is stable over a wide range of pH levels and is used in a number of applications such as food processing, institutional, veterinary, healthcare areas and medical devices. Single-active DDAC products are available at different active concentrations and solvent combinations.

Applications
• Cooling Water
• Disinfection Control
• Non-oxidising biocides are used across industry to control microbiological activity in a wide range of water systems, often in rotation with oxidising biocides. Biocidal performance is concentration dependant, so it is essential to monitor the activity levels closely in any system to ensure microbiological control.
• The Bardac 22 non-oxidising biocide test kits are based on novel colorimetric or titrimetric procedures and are designed for use by non technical persons as a site-based aid. Accurate biocide levels can be measured in minutes to ensure continued system control.
• There is it non-oxidising biocide test kits provide a simple solution to ensure bleed concentrations are in line with environmental consents.

Didecyldimethylammonium chloride (DDAC) is an antiseptic/disinfectant that is used in many biocidal applications. It causes disruption of intermolecular interactions and dissociation of lipid bilayers. It is a broad spectrum bactericidal and fungicidal and can be used as disinfectant cleaner for linen, recommended for use in hospitals, hotels and industries. It is also used in gynaecology, surgery, ophthalmology, pediatrics, OT, and for the sterilization of surgical instruments, endoscopes and surface disinfection.
Didecyl dimethyl ammonium chloride is a clear, yellow liquid, yellowish powder or colorless crystals. It has a mushroom-like odor. It is moderately soluble in water.

Sewer and Wastewater Treatment
Disinfectants used to treat sewage and wastewater include chlorine, chlorine dioxide, ozone, sulfur dioxide, hydrogen peroxide, and 1,3-dichloro-5,5-dimethylhydantoin. Products of decay include hydrogen sulfide, methane, nitrogen, carbon dioxide, and ammonia. Faulty equipment can generate dangerous levels of carbon monoxide.
Applying Wood Preservatives
Railroad ties, marine pilings, fence posts, and telephone poles may be pressure treated with creosote, pentachlorophenol, and ammoniacal copper arsenate (ACA) or chromated copper arsenate (CCA). [ILO Encyclo: Major Sectors and Processes: Occupational Hazards and Controls] Pentachlorophenol, creosote, and chromated copper arsenate were banned for sale in the United States to consumers as wood preservatives. CCA is still used commercially as a wood preservative.
Using Disinfectants or Biocides
Disinfectants are chemicals used to inhibit or kill microorganisms. Disinfectants are also called antiseptics or biocides. Disinfectants are generally used in physical media (solutions or on surfaces) while antiseptics are applied to skin or other living tissue. Some of these agents are also used as preservatives for food, drugs, and other domestic and industrial products. Many of these chemicals are skin and respiratory sensitizers. The following can cause occupational asthma: glutaraldehyde, formaldehyde, sodium bisulfite, chloramine T, hexachlorophene, chlorohexidine, benzalkonium chloride, isononanoyl oxybenzene sulfonate, lauryl dimethyl benzyl ammonium chloride, and isothiazolinones. A study of 175 workers exposed to chloramines, aldehydes, and quaternary ammonium disinfectants in the food industry showed increased acute irritation symptoms but not chronic respiratory symptoms.
