DTEA as Biocide

DTEA Original - Dow Chemical

The chemistry is from a family of known mineral flotation chemicals and corrosion inhibitors.

It was designed as an alkaline stable broad spectrum biocide and algaecide replacement which penetrated biofilm and also removed and tore off layered biofilm. Dow dropped the product in about 1999 at about the time it purchased the Angus and Union Carbide biocide lines. Original strategy called for marketing to Nalco, Betz, Calgon, Buckman, and related companies.  AWT, small, and medium companies were to buy through distributors. (The new chemistry is called DTEA II™ and is available on a near exclusive basis to AWT. small, and medium companies.)

TODAY - AMSA DTEA II™

IT IS the Swiss army knife of water treatment:

  • sold by AMSA, Inc. as an OEM product for private labeling
  • sold direct or through Bio-Source and Telomer to water treatment companies
  • an organic penetrant
  • water based in formula
  • stable and persistent at all pH levels
  • compatible with corrosion inhibitors
  • low foaming and controlled foam formulation (AMSA DTEA II™ F11)
  • protective of bare metal in water, thus prevents sludge build-up
  • not affected by oils, organics, or processed stream leaks
  • dislodges and converts sludge to water slurry
  • does not react with ammonia or hydrogen sulfide

Original Dow DTEA Cleaner (see improved DTEA IITM)

The original Dow DTEA Cleaner was made with 15% decylthioethylamine, propylene glycol, water, and propionic acid. The chemical make up was identical to the biocide formula. The cleaner formula could not be used or claimed for biocidal purposes.

Original Dow Antimicrobial DTEA Biocide

The original formula DTEA Biocide was EPA registered in 1993 by Dow Chemical. This included registration for use in key states, such as California. In addition, no UN Placard was needed and was shipped non-hazardous class.

The main use was as a quick kill biocide, as listed below, that also removed and prevented biofilm.

  • Sulfate reducers
  • Nitrifying bacteria
  • Fungi
  • Algae
