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. There are many variations available of our Bardac® 22 product, including:

The Bardac® 22 product line shows a broad spectrum of activity against both gram-positive and gram-negative bacteria and is also effective on fungi and viruses, including those that are enveloped. Showing a high tolerance to hard water (above 350ppm), it remains active in the presence of heavy organic soiling. Its impressive surfactant and wetting properties make it one of the multipurpose biocides of choice for cooling systems and swimming pool water treatment as part of formulations.
