Organic biocides In paper industry biocides are often categorised into two groups, oxidising and organic (= non-oxidising) biocides. Chapter Oxidising biocides describes the differences between these two groups. In short, oxidising biocides react non-specifically with plurality of cell components, whereas organic biocides usually react with more specific target molecules in a microbial cell. Common for

Organic biocides
After reading this article you will..
- understand that organic biocides are a heterogeneous group of biocide molecules with varying mechanisms of action.
- know that organic biocides contain both quick-killing and slow-acting = preservative chemicals.
- understand that the choice of biocide depends on nature of the treated material and on performance target of the treatment, but also on regulatory requirements of the biocide use and possible food-contact compliance requirements of the produced paper/board grade.
