Abstract
Aqueous glyphosate formulations comprising a surfactant derived from metathesized natural oil feedstocks are disclosed. The formulations comprise a glyphosate salt, water, and a surfactant derived from a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives. The surfactant is selected from C10 or C12 amine oxides, C10 or C12 quats, C10, C12, or C16 amidoamines, C10 or C12 amidoamine oxides, C10 imidazoline quats, C10 or C12 amidoamine quats, C10, C12, or C16 betaines, C16 amidoamine betaines, C18 diamidoamines, C18 diamidoamine oxides, C18 diamidoamine diquats, C18 diamidoamine oxide quats, C18 diamidoamine oxide betaines, Cis diamidoamine monobetaines, C18 diamidoamine monobetaine quats, C18 ester amidoamine quats, and amidoamines and their oxidized or quaternized derivatives made from self- or cross-metathesized palm or soybean oil. The surfactants noted above impart substantial stability to highly concentrated glyphosate formulations at, above, and below room temperature and perform as well or better than commercial alternatives.
