BIT- 20 is a low-toxicity biocide in propylene glycol/glycerine solution for
protection against yeast, bacterial and fungal growth in the wet state. It is stable over a broad
pH range of 4 – 12, and a broad temperature range.


BIT 20 can be used to control the growth of a wide spectrum of microorganisms – bacteria,
mould fungi and yeasts, in emulsion paints, adhesives concrete additives and other water
treatment formulations.
It is easy to formulate BIT 20 into many products, as it is miscible with water in any ratio.
Moreover, BIT 20 has a good thermal stability and low volatility, it can also be added at a very
early phase in the production process without affecting the active content during the higher
temperature process. BIT 20 is stable over a wide pH range of pH 4 – 12. All in all, it can be used
in a wide scope of anti-microbial applications.
Also available is BIT 10 (10% active content) and BIT 33 (33% active content)
