1. Dodecylguanidine Hydrochloride is used for the control of algae, bacteria, fungi. 

2. Dodecylguanidine Hydrochloride is used in a wide range of industrial process waters, air washing systems, industrial recalculating water cooling towers, oil field water systems, oil recovery drilling fluids, sewage disposal lagoons and pulp & paper mill systems.

3. Dodecylguanidine Hydrochloride can also be used for material preservation such as adhesive systems (non­food contact), paints, coatings & stains, pigments, dyes & filler suspensions, polymer dispersions & emulsions,pulp & paper mill processing and food packaging.


Strong against biofilm, sulfate reducing bacteria and Legionella

Non-oxidizing agent

Compatible with chlorine and typical active ingredients in water treatment

DGH has a double mode of action. It breaks up the biofilm and kills isolated bacteria by membrane disruption.


1.  Everyday biocide

    DGH can be used as regular biocide to effectively control microbial growth

    Comparable treatment costs to CMIT/MIT

    Can be combined with other biocide for increased efficacy spectrum

2.  Specialty biocide

    Use as add-on to your regular biocidal program, e.g. for

    Highly contaminated systems

    Weekly system clean-up
