Abstract:
1. A stable herbicidal formulation which comprises at least one herbicidally active compound and at least one adjuvant surfactant, wherein said surfactant comprises an ethoxylated alkyl(ether)amine with peaked distribution, said ethoxylated alkyl(ether)amine with peaked distribution characterized by a degree of peaking that is at least 5% higher than that of the conventional non-peaked ethoxylated alkyl(ether)amines having the same carbon-chain length and average EO chain length prepared via conventional base catalysis, wherein conventional base catalysis comprises NaOH-catalyzed reaction of RNH 2 with alkylene oxide conducted entirely under autogenous pressure up to 90 psig (621 kPa) at a catalyst concentration of 0.2 wt. % and a temperature between 160° and 180° C.
