Dodecylguanidine Hydrochloride (DGH) - A unique active ingredient
Advantages of DGH
- Proven compatibility for water treatment, polymer emulsions and detergents*
- Broad pH application range (4-12)
- Chemically stable
- No formaldehyde, no AOX
- Within dosage recommendation completely soluble in water
- BfR approvals for applications with food contact (BfR XIV, BfR XXXVI)
- No sensitizer -> No H 317 limit
- Due to cationic nature of DGH the compatibility with anionic or non ionic chemicals should be tested
* We support the testing & development of DGH in other applications, such as Paints & Coatings or Glues. Please contact us!
- 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.
It can be used in two ways
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
