Dodecylguanidine hydrochloride

Dodecylguanidine hydrochloride (CAS 13590-97-1), sold commercially as Metasol DGH, is a cationic biocide with broad-spectrum antimicrobial activity against bacteria, fungi, and algae. It is used across industrial and agricultural applications where microbial control in aqueous systems or on treated surfaces is required. In agriculture, it functions as an active ingredient in fungicidal formulations.

These formulations target post-harvest pathogens and soil-borne disease in crop protection programs. Water treatment operations use it to control algae and bacterial growth in cooling towers and industrial process water. It is also effective in recirculating systems. In textile and leather processing, it is applied as a preservative treatment to inhibit microbial degradation during wet processing and storage.

Paper and pulp manufacturers incorporate it into slimicide programs to prevent biofilm formation. This prevents biofilms that cause sheet defects and equipment fouling in the manufacturing process. Dodecylguanidine hydrochloride is typically supplied as an aqueous solution, with concentration levels varying by supplier and end-use specification. Technical grade is the standard commercial form.

Buyers should confirm active content and formulation compatibility when evaluating supply sources. Solution strength directly affects dosing calculations and handling requirements for industrial applications.
