  • Publication number: 20230018007
    Abstract: Agricultural compositions that employ structured surfactant systems to suspend water-insoluble or sparingly soluble agricultural actives and/or adjuvants are disclosed. Also disclosed are agricultural compositions that combine structured surfactant systems with electrolytes to form structured electrolyte compositions. The structured surfactant systems, both with and without electrolyte, suspend one or more agricultural actives and/or crop oil and non-aqueous adjuvants to provide agricultural compositions that can combine combinations of actives in a single, stable composition.

  • Patent number: 10694743
    Abstract: Agricultural compositions having reduced aquatic toxicity are disclosed. The compositions comprise an agricultural active, a monounsaturated C10-C12 fatty amine ethoxylate, and optionally water. The compositions may further comprise an auxiliary surfactant, a solvent, or both. In certain preferred aspects, the agricultural active is a glyphosate salt. Agricultural compositions comprising a monounsaturated C10-C12 fatty amine ethoxylate have good herbicidal efficacy. Unexpectedly, the monounsaturated C10-C12 fatty amine ethoxylates have reduced aquatic toxicity when compared with their saturated analogs.

  • Patent number: 10322994
    Abstract: Fatty amide compositions and their derivatives are disclosed. The fatty amides comprise a reaction product of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with a primary or secondary amine. Derivatives made by reducing, quaternizing, sulfonating, alkoxylating, sulfating, and sulfitating the fatty amide are also included. The amine reactant can be diethylenetriamine or (2-aminoethyl)ethanolamine, which provide imidazoline amides or esters, respectively. In one aspect, the ester derivative of the C10-C17 monounsaturated acid or octadecene-1,18-dioic acid is a lower alkyl ester. In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin. The compositions are valuable for cleaners, fabric treatment, hair conditioning, personal care, antimicrobial compositions, agricultural uses, and oil field applications.
