There are two important applications for DMSO in the agrichemical applications. DMSO is used as a liquid solvent to formulate agricultural chemicals and as a solvent for the synthesis of agrichemical actives.
The powerful solvent properties of DMSO allow for high actives loading, resulting in highly concentrated formulations. In agrichemical formulations, DMSO has the ability to dissolve highly insoluble active ingredients. It provides an alternative to more hazardous dipolar aprotic solvents which are being regulated out of agrichemical applications – particularly N-Methyl Pyrollidone (NMP). DMSO is completely miscible in water and is naturally biodegradable.
DMSO is a safe and effective liquid formulation solvent for a range of active ingredients used in herbicide, insecticides and fungicide formulations including propiconazole, pinoxaden, pyroxasulfone, mentaconazole, imazethaphyr, imazamethabenz-methyl, trubupirimphos, cyfluthrin, glysophate and imidacloprid. Single or combined active ingredient formulations have widely been formulated with DMSO.
