DDAC 50 is a twin chain quaternary ammonium. It is a modern and safe biocide. It features broad spectrum activity against both gram positive and gram negative bacteria, fungicide and mildewcide, active against enveloped viruses (e.g. Hepatitis B, HIV), tolerance for anionic contaminants, high tolerance to hard water, maintains efficacy in presence of heavy organic soiling such as blood and protein, good surfactant and wetting properties. It has an amine content of approximately 1.5%.

DDAC50 is a strongly cationic product and therefore incompatible with formulations containing anionic components. It may, however, be used with other cationic or non-ionic compounds. Users are therefore strongly advised to carry out their compatibility tests prior to initial application.
Please note that the pH of DDAC50 on production is in the range 6.5 – 8.0 (2% aqueous solution) but this may drift downwards with time. Such variation has no effect on the product’s biocidal properties
PLEASE NOTE: This product is not for human or animal consumption.
The active agent of DDAC50 typically exhibits the highest biocidal efficacy of all quaternary compounds. The performance advantage is especially evident in the presence of hard water and organic soiling, compared with simple Benzalkonium chloride quaternaries. Given below are examples of relevant organisms against which it is particularly effective:
