What is Dodecylguanidine hydrochloride?
Dodecylguanidine hydrochloride (CAS 13590-97-1) is a cationic biocide with broad-spectrum antimicrobial activity against bacteria, fungi, and algae. Also marketed as Metasol DGH.
Where is Dodecylguanidine hydrochloride used?
- Agriculture: active ingredient in fungicidal formulations targeting post-harvest pathogens and soil-borne disease
- Water treatment: controls algae and bacterial growth in cooling towers and industrial process water
- Textile and leather processing: preservative treatment inhibiting microbial degradation during wet processing and storage
- Paper and pulp: slimicide programs prevent biofilm formation that causes sheet defects and equipment fouling
- It is also effective in recirculating systems.
Good to know: Buyers should confirm active content and formulation compatibility when evaluating supply sources; solution strength affects dosing calculations and handling requirements.
