Aqueous glyphosate formulations are described which comprise a surfactant derived from feed feeds of metatized natural oil; In one aspect, the compositions comprise a glyphosate salt, water, and a surfactant derived from a C10-C17 monounsaturated acid derived from metathesis, octadecene-1,18-dioic acid, or its ester derivatives; The surfactant is selected from C10 or C12 amine oxides, C10 or C12 cuats, C10 C12, or C16 amidoamines, C10 or C12 amidoamine oxides, C10 imidazoline cuats, C10 or C12 amidoamine cuats, betaines of C10, C12, or C16, C16 amidoamine betaines, C18 diamidoamines, C18 diamidoamine oxides, C18 diamidoamine dicuats, C18 diamidoamine oxide cuats, C18 diamidoamine betaine oxide, C18 diabemidoamine monohydrates of diamidoamine C18 monobetaines, C18 amidoamine ester cuats, and amidoamines and their oxidized or quaternized derivatives formed from the self-metathesis or cross-metathesis of palm or soybean oil; The surfactant indicated above imparts substantial stability to highly concentrated formulations of glyphosate at, above, and below room temperature and performs as well or better than commercial alternatives. |
