The synergistic effect of isothiazolinone in terms of its bactericidal efficacy and its alignment with industrial demands

19-03-2026

In the field of industrial anti-corrosion, traditional preservatives such as formaldehyde releasers and phenolic compounds are gradually being replaced by new technologies due to their toxicity risks and environmental burdens. Isothiazolinone, as a new generation of broad-spectrum fungicides, with its high efficiency, low toxicity and environmentally friendly characteristics, has become the core solution to replace traditional preservatives. Dalian Tianwei Chemical Enterprise, through technological innovation, has deeply integrated the bactericidal efficacy of isothiazolinone with industrial demands, promoting the industry to develop in a safer and more sustainable direction.

Technical core: Targeted destruction of microbial DNA


The bactericidal mechanism of isothiazolinone is based on its unique molecular structure. This compound forms covalent bonds with the DNA bases within the microbial cells through the active chlorine and sulfur atoms on the heterocyclic ring, directly destroying the DNA double helix structure, preventing the microorganisms from replicating their genetic material. This "irreversible inhibition" mechanism enables isothiazolinone to achieve a killing rate of over 99.9% against bacteria, fungi, algae, and other microorganisms, and the effect is visible within just a few minutes. For example, in the paper industry, the isothiazolinone product from Dalian Tianwei Chemical can inhibit the reproduction of sulfate-reducing bacteria in the pulp, avoiding the corrosion of equipment caused by the sulfur hydrogen produced by microbial metabolism.
