Abstract: The invention is a herbicidal composition containing an alkanolamine salt of an dicamba capable of remaining as a single phase liquid over a period of at least 1 week and containing low amounts of water and high loadings of the salt. Such herbicidal compositions are capable of remaining liquid in the absence of high amounts of water, thereby enhancing their capacity to remain liquid over an extended period of time when exposed to environmental conditions to improve their effectiveness to transport the active salt through a leafy substrate and can reduce transportation costs by increasing the salt loading without compromising the stability of the composition.

Abstract: The invention generally involves combining specialty amines with herbicidal carboxylic acids to form a new generation of salts with improved characteristics. The salts contain a cation of an amine and an anion of a carboxylic acid herbicide. The amine is advantageously selected from mono-isobutylamine (MIBA), N-methylaminoethanol (MMEA), dimethylaminopropylamine (DMAPA), 2-dimethylaminoethanol (DMAE), methyldiethanolamine (MDEA), and 1,2-diaminopropane (1,2-DAP). The amine-herbicide combinations may possess one or more improved characteristics, including maximum loading, wettability, drift, viscosity, and volatilization.

Abstract: A process is described for obtaining free flowable, carrier free powders from aqueous solutions of deliquescent quaternary ammonium compounds in a two step process, comprising a drying and a powder mixing step. The excellent free-flowing and stability characteristics of the final product could only be obtained when among possible other additives at least one univalent metal fatty acid salt is added to the liquid phase in the drying step and at least one multivalent metal fatty acid salt in the powder mixing step. A surprising synergy was observed between these additives when applied as described in the present invention.
